Mitsubishi Electric: The 100-Year Electrification Giant
I. Introduction & Episode Roadmap
On a muggy summer morning in 1921, workers at Mitsubishi Shipbuilding's Kobe yard watched as engineers hoisted a massive marine electric motor destined for an ocean-going vessel. That year, the electrical machinery manufacturing division was spun off from Mitsubishi Shipbuilding at the Kobe Shipyard to become Mitsubishi Electric Corporation—a moment that would birth one of the world's most diversified electronics conglomerates.
Today, Mitsubishi Electric commands a market capitalization of approximately $57.6 billion and generates trailing twelve-month revenue exceeding $37 billion. In fiscal year 2025, both revenue and operating profit reached record highs, driven by increases in the Infrastructure and Life segments, as well as an improvement in the Semiconductor & Device segment. But behind these impressive figures lies a story of zaibatsu DNA, decades of diversification mastery, a devastating quality scandal, and an ongoing transformation toward what management calls "Circular Digital-Engineering."
How did a marine electric motor factory evolve into a global powerhouse spanning factory automation, air conditioning, satellites, and spiral escalators? How did the company survive three decades of systematic quality fraud that forced the resignation of its CEO and chairman? And can Mitsubishi Electric position itself for the AI and decarbonization era while recovering stakeholder trust?
This deep dive explores the strategic arc of a company that mirrors Japan's own industrial transformation—from shipbuilder to technological diversifier, from wartime manufacturer to global electronics giant, and now from scandal-plagued legacy player to aspiring digital solutions leader.
The story touches three major themes: the enduring power and complexity of Japan's keiretsu networks, the strategic logic behind extreme diversification, and the cultural dynamics that allowed quality failures to persist for decades. For investors, the Mitsubishi Electric case offers lessons about the durability of embedded industrial relationships, the challenges of corporate transformation in Japanese conglomerates, and the tensions between decentralized operations and accountability.
II. The Mitsubishi Zaibatsu Origins
Picture the chaos of Japan in 1870: the Tokugawa Shogunate had just collapsed, samurai were losing their traditional roles, and a new Meiji government was desperately seeking to modernize the nation. Into this tumult stepped a brash young man named Yatarō Iwasaki, born on January 9, 1835, in Aki, Tosa Province—now Kōchi Prefecture—into a provincial farming family.
Iwasaki's family had been members of the samurai warrior nobility, but his great-great-grandfather had sold off the family's samurai status in obligation of debts during the Great Tenmei famine. This fall from grace shaped the young Yatarō. He was brilliant but volatile—ambitious yet lacking the patience for conventional advancement.
Iwasaki left for Edo (Tokyo) at age nineteen for his education, but his studies were interrupted a year later when his father was seriously injured in a dispute with the village headman. Iwasaki accused the local magistrate of corruption for refusing to hear his case, and was subsequently sent to prison for seven months. This early brush with injustice didn't break him—it hardened his resolve.
After his release, Iwasaki returned to Edo, where he socialized with political activists and studied under Yoshida TĹŤyĹŤ, a reformist and modernization advocate from Tosa Province. Yoshida was employed by Yamauchi Toyoshige, the daimyĹŤ of the Tosa Domain, and he influenced Iwasaki with ideas of opening and developing the then-closed Japan through industry and foreign trade.
The company was established as a shipping firm by Iwasaki YatarĹŤ in 1870 under the name "Tsukumo Shokai." In 1873, its name was changed to Mitsubishi Shokai; Mitsubishi consists of two parts: "mitsu" meaning "three" (as in the three oak leaves from the crest of the Yamauchi or Tosa family that ruled over YatarĹŤ's birthplace and employed him) and "hishi" meaning "water caltrop," and hence "rhombus," which is reflected in the company's logo.
The name itself tells the story: YatarĹŤ chose not to name the company after himself but created a symbol that merged his own family crest with that of the Tosa Clan. Yataro Iwasaki chose the three-diamond mark as the emblem for his company. The mark is suggestive of the three-leaf crest of the Tosa Clan, Yataro's first employer, and also of the three stacked rhombuses of the Iwasaki family crest.
From 1874 to 1875, Iwasaki was contracted by the Japanese government to transport Japanese soldiers and war materials. The Japanese government purchased a number of ships for the Japanese Expedition of 1874 to Taiwan against the Paiwan Aborigines, and these ships were later given to Mitsubishi after the expedition was finished in 1875. This created strong links between Mitsubishi and the Japanese government that ensured the new company's success.
This relationship between Mitsubishi and state power would define the zaibatsu model. IWASAKI Yataro built his fortune in the shipping industry, and he took advantage of the Taiwan Expedition in 1874 to rapidly grow his business, succeeding in establishing his position as a political merchant.
Diversification came naturally. Mitsubishi's diversification was mostly into related fields. It entered into coal-mining to gain the coal needed for ships, bought a shipbuilding yard from the government to repair the ships it used, founded an iron mill to supply iron to the shipbuilding yard, started a marine insurance business to cater for its shipping business. In 1881, the company bought into coal mining by acquiring the Takashima Mine, followed by Hashima Island in 1890, using the production to fuel their extensive steamship fleet.
Iwasaki died of stomach cancer on February 7, 1885, aged 50. He never saw the full flowering of his creation. But Hisaya was succeeded by his cousin Koyata in 1916, and during his time as president the group saw a significant expansion. In 1917, he funded the establishment of an optics company and became the majority shareholder, which later became Nikon.
Koyata, a graduate of Cambridge University, incorporated the divisions as semiautonomous companies. He steered Mitsubishi to leadership in such sectors as machinery, electrical equipment, and chemicals. This organizational model—semi-autonomous divisions under a family-controlled holding structure—would become the template for the modern Mitsubishi keiretsu.
For investors, the zaibatsu origins matter because they explain Mitsubishi Electric's DNA. The company inherited a culture of government relationships, vertical integration thinking, and diversification logic. But the zaibatsu structure also created challenges: siloed operations, diffuse accountability, and a culture where loyalty to the group sometimes overshadowed outside obligations—dynamics that would later contribute to the quality scandal.
III. Birth of Mitsubishi Electric & Early Growth (1921–1945)
Mitsubishi Electric Corporation was founded in 1921 when Mitsubishi Shipbuilding Co. (currently Mitsubishi Heavy Industries, Ltd.) spun off its marine electric motor factory in Kobe. The logic was straightforward: the parent company's electrical operations had grown substantial enough to warrant independence, and Koyata Iwasaki's strategy of semi-autonomous divisions demanded clear organizational boundaries.
Mitsubishi Electric originated in 1905 in the parent company's Kobe shipyard as a manufacturer of electrical equipment for ships and mining. Five years later, the division constructed a large-capacity induction motor (the first in Japan) and a turbine generator. By the time of the 1921 spin-off, the operation had sixteen years of accumulated expertise.
Shares in the new company, Mitsubishi Electric, were sold to investors, and the capital raised was used to acquire new manufacturing space and equipment. But the young company faced a challenge common to Japanese manufacturers of that era: technological inferiority to Western competitors.
Like NEC, which had negotiated an extensive cooperative agreement with Western Electric, Mitsubishi Electric became closely associated with another American electronics manufacturer, Westinghouse Electric. Their agreement, concluded in 1923, provided Mitsubishi Electric with Japanese marketing and licensing rights for a number of Westinghouse products and designs. As a result, Mitsubishi Electric successfully built a large 2300-kVA vertical-axis-type hydraulic generator.
This Westinghouse partnership shaped Mitsubishi Electric's development for decades. The company learned Western manufacturing methods, gained access to patents, and built the technical foundation that would later enable independent innovation. Between the 1930s and possibly 1970s, Mitsubishi Electric produced elevators under technical partnership with Westinghouse Electric Corp. of USA because Mitsubishi had signed a technical licensing agreement with Westinghouse in 1923.
Mitsubishi Electric remained the favored supplier of large and small electrical devices to all the various Mitsubishi companies while maintaining its expertise in maritime electronics and gaining new strengths in other fields like communication, power transmission, lighting, and consumer appliances. In 1931, Mitsubishi Electric began commercial production of passenger elevators and started exporting fans to China and Hong Kong. Two years later, reacting to greater domestic demand for home appliances, the company began marketing refrigerators.
The desk fan deserves special mention. In Japan's hot, humid climate, this humble appliance became Mitsubishi Electric's first commercial success. The revenue from desk fan sales funded the company's expansion into escalators, elevators, and televisions. Consumer products helped smooth revenue cycles that might otherwise have been dominated by lumpy industrial orders.
But the 1930s were a difficult period for Japan's zaibatsu conglomerates like Mitsubishi. The 12 major Japanese companies had become inextricably linked to the government through a 50-year industrial modernization program. But the government had recently been taken over by a quasi-fascist element in the military whose aim was to establish absolute Japanese supremacy in eastern Asia.
In their effort to modernize and arm Japan for war, the militarists called upon industrial concerns such as Mitsubishi Electric to provide a vast array of equipment. While Mitsubishi Heavy Industries eventually became the principal manufacturer of warplanes, particularly the notorious Zero, Mitsubishi Electric developed radio sets for the Zero and other aircraft.
With World War II well under way, Mitsubishi Electric came under increasingly strict control by the government. The company was compelled to follow all military directives and, as a result, in 1944 established a research laboratory whose goal was to develop new instruments for naval and aerial battle management. By August 1945, however, the war was lost, and Japan's battered industries came under the control of government agencies directed by the occupation authority.
The wartime period left ambiguous legacies. On one hand, military production forced rapid technological advancement—radar, communications, power systems. On the other, the zaibatsu-military nexus would make Mitsubishi Electric a target for postwar dissolution. The company emerged from the war with both enhanced capabilities and existential vulnerability.
IV. Post-War Dissolution, Reconstruction & Rise (1946–1990)
After the Second World War, under the Allied Occupation's policy to dissolve zaibatsu, the Mitsubishi conglomerate underwent significant restructuring. Until the Cold War made the Eastern Bloc more menacing than the possible revival of a strong Japan and Germany, the occupation forces' initial aim was to weaken the Japanese economy so that the country could never wage war against them. Under this policy, Mitsubishi as a group was dissolved.
On October 20, 1945, only two months following Japan's surrender to the Allied Forces, Japan was dealt a further economic hardship when the Allied Command ordered the disbanding of all zaibatsu. The order was given because Allied Command considered the military and the zaibatsu to have been ultimately responsible for driving Japan into the war.
Mitsubishi Heavy Industries and Mitsubishi Chemical were split into three separate entities. On his deathbed, Koyata Iwasaki staunchly defended his actions, asserting that he had done his utmost for his country and had nothing to be ashamed of. Despite his resistance, he could not defy the tide of the times.
Mitsubishi Electric survived the dissolution relatively intact—it didn't face the same fragmentation as Heavy Industries. But the company lost access to the zaibatsu coordination mechanisms that had funneled business its way.
Mitsubishi Electric began the enormous task of rebuilding its business after the war. Helped by reconstruction loans but impeded by difficult labor regulations, supply shortages, weak domestic demand, and the dissolution of the zaibatsu, Mitsubishi Electric struggled to survive. By 1948 the company had resumed production of consumer and some industrial items, including straight-tube fluorescent lamps. Military production, once the primary source of Mitsubishi's profits, had been banned by the occupation authority. Having reestablished marketing agreements with foreign manufacturers, Mitsubishi Electric began selling televisions in Japan in 1953.
The Korean War changed everything. After completing several successful industrial projects, Mitsubishi resumed foreign operations in 1954 with the completion of a power substation in India. As a result of the Korean War, the American government decided to end its extractive, punitive policies toward Japan.
In 1954, Mitsubishi Corporation was reformed, and the Mitsubishi Friday Club was established to foster camaraderie and information exchange among the chairpersons and presidents of major Mitsubishi companies. The Friday Club became the coordination mechanism for the modern keiretsu—an informal gathering where member companies shared information and arranged mutual support, all while maintaining formal independence.
Mitsubishi Electric became a leader in electrical machinery and in home appliances. The company rode Japan's postwar economic miracle, supplying power equipment for the nation's rebuilding, consumer appliances for newly prosperous households, and industrial automation for rapidly modernizing factories.
Key milestones marked the company's technological advance. By 1968, Mitsubishi Electric commercialized the first gas-insulated switchgear (GIS) in Japan and completed the first Mitsubishi nuclear power generator. By 1984, it became the first company in the world to achieve production of 10,000 gas circuit breakers.
Mitsubishi supplied and installed high speed elevators at the Yokohama Landmark Tower in Yokohama, Japan in 1993. With a speed of 12.5 meters per second, they were the fastest elevators in the world at the time of their completion and continued to hold such title until 2004 when it was surpassed by Taipei 101's high speed elevators.
The pattern that emerged—world-leading positions in niche industrial segments, combined with solid consumer appliance businesses—would define Mitsubishi Electric's strategic identity for decades.
For investors, the postwar reconstruction reveals how Mitsubishi Electric's competitive position depends on the broader keiretsu ecosystem. The Friday Club relationships, while legally informal, provide preferential access to contracts from fellow Mitsubishi companies and create barriers for outside competitors seeking to penetrate Japanese industrial markets.
V. Global Expansion & Diversification Era (1990–2010)
In March 1985, Mitsubishi Electric changed the very concept of escalators moving in a straight line, and the world's first escalator that goes up and down along a spiral curve, Mitsubishi Spiral Escalator was delivered in 2 units to the Tsukuba Creo Square Shopping Center in Japan. The spiral escalator is formed by bending a conventional straight escalator in an arc shape in order to respond to the demands of diversified building designs, and passengers can enjoy a wide-angle view inside the building as they move.
The world's first and only spiral escalators. Form and function combine to deliver a one-of-a-kind experience for customers. This is a people-moving solution designed to really move people. Mitsubishi Electric remains the only company to manufacture spiral escalators in the world.
This product illustrates Mitsubishi Electric's diversification strategy: find niches where engineering excellence creates monopoly-like positions. Spiral escalators aren't a mass market—perhaps a hundred installations globally—but they command premium prices and generate recurring service revenue while reinforcing the company's reputation for technical leadership.
Similar logic applied across segments. Mitsubishi started installing elevators in North America in 1985. In 1988, the company delivered the first overseas spiral escalator to the United States. Mitsubishi delivered the world's fastest passenger elevator at the time: 1230m/min (Shanghai Tower, China).
But not all diversification efforts succeeded. The company learned hard lessons about competing outside its core industrial strengths.
Mobile phones, from 1999 to 2008. Created for NTT Docomo. Mitsubishi Electric quit the mobile phone business in April 2008 after decrease in shipments. They estimated a temporary loss of 17 billion Yen in income before income taxes.
LCD TVs, starting in 2004 and ending in 2024. DLP High Definition TVs, until December 2012. Mitsubishi Electric then focused on professional and home theater DLP projection applications, and is no longer manufacturing televisions for the consumer market.
The consumer electronics exits underscore a strategic reality: Mitsubishi Electric thrives in B2B industrial segments where engineering depth matters more than consumer brand management or rapid product cycles. Mobile phones and televisions required different capabilities—fast fashion sensibilities, massive marketing budgets, consumer insight—that didn't align with the company's DNA.
Strategic acquisitions focused on core strengths. The company acquired Nihon Kentetsu, a Japanese home appliance manufacturer, in 2005. In 2015, Mitsubishi Electric acquired DeLclima, an Italian company that designs and produces HVAC and HPAC units, renamed Mitsubishi Electric Hydronics & IT Cooling Systems SpA in 2017.
Mitsubishi Electric's air conditioning and refrigeration systems business in the U.S. has been expanding rapidly since 1980. In 2018, Mitsubishi Electric's air conditioning and refrigeration systems business in the U.S. established a joint venture company with Trane Technologies plc, known as Mitsubishi Electric Trane HVAC US LLC.
This joint venture with Trane represented a different approach to the U.S. market: partnering with an established player rather than trying to build distribution alone. Mitsubishi has been the #1 selling ductless brand in the U.S. for years. The combination of Mitsubishi's ductless technology with Trane's distribution network and service capabilities created a formidable competitive position.
By the end of this era, Mitsubishi Electric had established itself as a diversified industrial electronics conglomerate with particular strength in factory automation, building systems (elevators/escalators), HVAC, automotive equipment, and power semiconductors. The portfolio seemed well-positioned for long-term growth. But beneath the surface, systemic problems were incubating that would explode into public view.
VI. The Quality Scandal Crisis (2021–2023) — A Major Inflection Point
In June 2021, a routine audit revealed something disturbing at Mitsubishi Electric's Nagasaki Works: the company had been performing fraudulent preshipment inspections on air conditioning equipment for trains. But this wasn't a recent slip. The company's then-President and CEO Takeshi Sugiyama quit over "three decades of systematic deceit," a period during which the electronics manufacturer faked inspection reports for air conditioners and brake compressors installed on trains.
The revelations cascaded. Mitsubishi Electric cheated on inspections and engaged in other bad behavior at 70% of its factories in Japan, according to the latest report in an ongoing investigation that points to deep-seated problems at one of the nation's leading industrial groups.
The reports detail a culture in which staff, and managers, often fudged test results to get products out the door. While the cheating did not see life-threatening flaws left in products, the investigation has found that lax quality control is pervasive across the company and its many subsidiaries. For example, the corporation's power distribution systems unit didn't properly conduct partial discharge tests—for 15 years, meaning 4,448 units went out the door in unknown condition. Tests to determine that units could withstand lightning strikes were skipped, too.
The latest investigation report found 101 new instances of cheating, taking the total to 148. The scope kept expanding. For transformer products, 8,363 products were shipped from 1982 to March 2022, and of these 3,384 were not tested properly—spanning 40 years. Approximately half were delivered within Japan and half shipped abroad.
In October 2021, former chairman Masaki Sakuyama resigned from Mitsubishi Electric following the release of an initial report on the quality control scandal. Two top executives gone in months.
What enabled such prolonged fraud? "Mitsubishi is a silo company, leaving experts to claim that the setting up of individual operations resulting in issues and scandals being easier to hide. The highly siloed organisation keeps divisions isolated from each other with problems often hidden from other layers of management. Individual business units are quite powerful at Mitsubishi Electric even compared with their competitors and that there are structural problems that top management can't see," said Hideki Wakabayashi, a professor at the technology management department of the Tokyo University of Science.
An investigation conducted after the 2018 scandal found that the problems were rooted in a lack of attention to quality due to insufficient training, along with weak quality control measures. At the time the Company said they would fix the problems yet despite this commitment by management, similar problems continued to emerge, raising doubts as to whether the probe and response did enough.
The pattern fit a troubling broader context. In 2016, Mitsubishi Motors—a sister company—came under fire for inaccurate fuel-economy test reports leading to resignations. In 2000, Mitsubishi admitted to a 30-year cover-up of auto defects and said it would recall a million cars. The Mitsubishi name, it seemed, carried not just prestige but also cultural problems that transcended individual companies.
The company is still waiting a final report on the full extent of the problems. In the meantime, a company task force is attempting to create a new corporate culture. The company has updated its internal corporate slogan—from "Changes for the Better"—to "Changes for the Better start with ME."
The ISO certifications that industrial customers rely on faced suspension. Multiple factory certifications were suspended, damaging the company's ability to win contracts requiring quality-system compliance.
For investors, the scandal revealed several critical dynamics. First, the silo structure that enabled decades of growth also enabled decades of hidden fraud. Second, weak corporate governance—with internal directors dominating the board—failed to surface problems. Third, the cultural dynamics of Japanese manufacturing—pressure to meet delivery schedules, deference to superiors, reluctance to surface problems—created the conditions for systematic failure.
The scandal also demonstrated durability: despite the revelations, Mitsubishi Electric's stock didn't collapse, its customers didn't flee en masse, and the business continued generating profits. This suggests either remarkable customer lock-in, limited alternatives, or patience awaiting reform. Understanding which explanation holds determines the investment thesis.
VII. Strategic Transformation & Medium-Term Plan (2021–Present)
Into this crisis stepped Kei Uruma, who was appointed President and CEO in 2021, taking on the responsibility of shaping the company's future on a global stage. A graduate of Waseda University, he is well-known for his sharp business acumen and thoughtful leadership. His vision continues to guide Mitsubishi Electric through a period of dynamic growth and transformation.
Kei Uruma began his career at Mitsubishi Electric after graduating in 1982. Over the years, he held key roles in factory automation, corporate strategy, and international operations, especially in Europe. His leadership as Executive Officer and head of Public Utility Systems positioned him as a forward-thinking strategist. Later, he led the Corporate Strategic Planning Division.
He became the CEO of Mitsubishi Electric following a significant scandal involving the falsification of inspection records. Appointed as a leader for reform, he has focused on rebuilding trust, enhancing transparency, and strengthening governance to restore the company's reputation and uphold its ethical standards.
The reform agenda attacked the silo problem directly. It has been three years since improper quality control practices came to light in June 2021. It is also the third year since the three key reforms (quality assurance, organizational culture, and governance) launched in response to these incidents entered the full-scale implementation phase. In fiscal 2025, the company is accelerating efforts to embed and promote the key measures implemented to date.
At Mitsubishi Electric, we have been working to strengthen corporate governance and enhance the effectiveness of the Board of Directors by ensuring that the majority of board members are outside directors starting from fiscal year 2022. This governance restructuring marked a significant departure from traditional Japanese corporate boards dominated by insiders.
The strategic vision evolved under Uruma's leadership. The company built Serendie as a new digital platform to facilitate unprecedented interactions between devices, systems and services in various fields, and the data and knowledge aggregated from these interactions. The name "Serendie" is a portmanteau of serendipity and digital engineering. As a digital platform, it is organized around a data analysis platform and a Web API integration system.
Management identified five Key Growth Businesses that can make major contributions to addressing social challenges in domains expected to grow at a high rate globally. The company committed to investing resources of ÂĄ2.8 trillion, up ÂĄ0.8 trillion from the previous medium-term management plan, centered on these Key Growth Businesses.
Digital transformation became central to the strategy. The company committed to investing ÂĄ130 billion in DX initiatives, expecting cost savings of ÂĄ190 billion cumulative for FY2024-FY2031.
Mitsubishi Electric Mobility commenced operations in April 2024. The company will continuously promote structural reform to enhance profitability of the automotive equipment business. This spinout of the automotive equipment business into a distinct entity reflected the portfolio management philosophy—isolating troubled segments for focused turnaround.
Financial results demonstrated that the reforms and strategic investments were gaining traction. Revenue increased by 254.2 billion yen year-on-year to 5,257.9 billion yen and operating profit increased by 66.1 billion yen to 328.5 billion yen, both reached new record highs in FY2024. All the sub-segments posted an operating surplus due to efforts to improve profitability and efficiency.
In FY25, revenue reached ¥5,521.7 billion (+¥263.7 billion YoY) and operating profit reached ¥391.8 billion (+¥63.3 billion YoY)—both revenue and operating profit reached record highs.
For FY26, the company forecasts revenue of ¥5,400.0 billion (-¥121.7 billion YoY) and operating profit of ¥430.0 billion (+¥38.1 billion YoY)—although a decrease in revenue YoY is expected mainly from the impact of the stronger yen, operating profit is expected to increase.
Mitsubishi Electric Group will continue to strongly promote its business portfolio strategy and initiatives for improving business structure, while consistently providing shareholder returns. Mitsubishi Electric Group has decided to repurchase shares of the company's stock (ÂĄ100.0 billion planned).
For investors, the transformation story presents a classic "show me" narrative. Management articulates compelling strategic logic. Financial results demonstrate execution. But the fundamental question remains: has the cultural change penetrated deeply enough to prevent future scandals? That question may take years to answer definitively.
VIII. Current Business Segments Deep Dive
Mitsubishi Electric's diversification creates a complex but defensible portfolio. Revenue breakdown reveals the company's true strategic priorities:
Air Conditioning Systems & Home Products leads with approximately $9.42 billion in revenue, representing the company's largest segment. Daikin has a larger market share in Europe, while Mitsubishi Electric has a larger market share in Japan and some other Asian markets. In sixth place globally in HVAC, Mitsubishi Electric has surpassed Johnson Controls by capturing mainly industrial needs.
Automotive Equipment follows at approximately $6.24 billion. This segment faced the most restructuring pressure, leading to the spinout of Mitsubishi Electric Mobility in April 2024. The automotive business serves a customer base in transition—internal combustion to electric vehicles—requiring significant capital expenditure to remain relevant.
Factory Automation Systems generates approximately $5.06 billion. The most popular PLC, according to market share, was the Siemens Simatic PLC. The second most popular PLC was Rockwell Automation Allen Bradley PLC. Followed by Mitsubishi Melsec PLC. Alongside Germany's Siemens and Rockwell Automation of the U.S., Mitsubishi Electric is one of the global leaders in PLCs.
Building Systems (elevators/escalators) contributes approximately $4.13 billion. Mitsubishi Electric Building Solutions Corporation manufactures elevators, escalators, moving walks, spiral escalators and dumbwaiters. It is the largest Japanese elevator manufacturer and is among the biggest elevator manufacturers in the world. It also has the largest international presence in elevator market from all Japanese companies.
Otis Elevator Company is the largest vendor in the global Elevator and Escalator Market. The company's strong presence in key regions, innovative product offerings, and a wide portfolio of services have helped it maintain its leadership position. Mitsubishi competes effectively against this global leader through technological differentiation—particularly the spiral escalator monopoly—and strong positions in Asian markets.
Public Utility Systems generates approximately $2.85 billion, serving railways, power utilities, and public infrastructure.
Energy Systems contributes approximately $2.29 billion, including power generation equipment, transformers, and switchgear—the segment where much of the quality scandal occurred.
Semiconductor & Device generates approximately $1.93 billion, focused primarily on power semiconductors for automotive and industrial applications.
Defense & Space Systems contributes approximately $1.71 billion, including satellite systems and defense electronics. The Smart Lander for Investigating Moon (SLIM), developed by the company under contract with the Japan Aerospace Exploration Agency (JAXA), successfully landed on the lunar surface on January 20, 2024. This is Japan's first lunar landing, making it the fifth country to safely land a spacecraft on the Moon.
Data collected by JAXA confirmed that the precision touchdown was just 55 meters east of the target landing point, a level of accuracy that far surpasses that of conventional lunar landings, which are typically within several kilometers of their targets, making this an unprecedented achievement.
The segment mix tells an important story: Mitsubishi Electric's three key top-line drivers—FA systems, automobile equipment, and air conditioning systems/home appliances—together make up about 60% of revenue. This concentration creates both opportunity (scale in growing markets) and risk (exposure to cyclical downturns in these sectors).
For investors, the diversification offers some protection against sector-specific shocks, but the businesses share common dependencies on manufacturing capital expenditure cycles and Asian economic growth. The portfolio isn't recession-proof—but it is more resilient than pure-play competitors.
IX. Recent Strategic Investments & Future Bets
Mitsubishi Electric's capital allocation reveals management's conviction about future growth drivers. Three major investment themes dominate: semiconductors, U.S. energy infrastructure, and HVAC localization.
Semiconductor Expansion
Mitsubishi Electric held a completion ceremony on October 1, 2025, for its new power semiconductor factory in Kumamoto Prefecture, Japan. The facility will produce silicon carbide (SiC) power semiconductors, primarily targeting the electric vehicle and industrial markets.
Mitsubishi Electric has successfully completed construction of its cutting-edge silicon carbide (SiC) power semiconductor manufacturing facility located in Kikuchi, Kumamoto Prefecture, Japan. The newly built six-story plant, spanning approximately 42,000 square meters, is part of the company's Shisui plant expansion and represents a significant $680 million investment in advanced semiconductor technology.
The new facility will start operations in November 2025, and the company will aim to start mass production in 2027. Power semiconductors, which control electric currents and voltages, are used in electric vehicles and home appliances.
The factory, originally scheduled to start operation in April 2026, will be put into production in November 2025, about 5 months ahead of schedule. The accelerated timeline suggests strong customer demand and execution capability.
The new facility will manufacture silicon carbide power semiconductors, for which EV-related demand is expected to grow in the medium-to-long term as they have a higher energy efficiency than silicon-based chips. The company has postponed parts of its equipment enhancement plan for the new facility to fiscal 2031 and beyond, due to a slower-than-expected increase in demand in the EV market. "We will decide how many production lines to install by examining market conditions and other factors," Mitsubishi Electric President Kei Uruma told reporters.
Mitsubishi Electric's goal is to increase the sales proportion of SiC in its power semiconductor business to over 30% by fiscal year 2030.
U.S. Energy Infrastructure
Mitsubishi Electric Power Products, Inc., in collaboration with its parent company Mitsubishi Electric Corporation in Japan, announced an $86 million investment in advanced switchgear production and power electronics in the U.S. This investment is driven by the increasing demand for transmission and distribution grid products as the U.S. moves toward renewable energy and decarbonization goals. Mitsubishi Electric Corporation's approval of the MEPPI investment represents a broader strategy to strengthen its production capabilities of energy systems both in Japan and overseas.
MEPPI will construct a new approximately 160,000 square foot Advanced Switchgear Factory in Western Pennsylvania, marking MEPPI's first new manufacturing facility in over a decade. Initially, the factory will focus on the production of both vacuum and gas circuit breakers.
The company, which is investing at least $86 million to construct a new advanced switchgear factory and expand its existing power electronics business in the Pittsburgh region, will create 200 new jobs and retain 806 existing jobs.
HVAC Manufacturing Localization
Mitsubishi Electric Corporation announced it will invest U.S.$143.5 million to retrofit a U.S.-based factory to make variable-speed compressors that are a key component of high-efficiency heat pumps. As part of Mitsubishi Electric US Holdings, Inc., the Maysville, Kentucky-based factory currently manufactures and sells automotive electrical equipment. Production of the compressors, targeted to start in October 2027, is expected to help the company meet growing demand in the United States for low-greenhouse-gas-impact and energy-efficient HVAC solutions. Initial estimated annual capacity will total 1,000,000 compressors. When complete, the revamped factory will represent the first time that variable-speed compressors using twin rotary technology for highly efficient ductless heat pumps will be manufactured in the United States.
A significant majority of these types of compressors are currently built in Asia. The U.S. subsidiary, MELCO HVAC US, Inc., is pleased to receive a $50 million award from the U.S. Department of Energy for the domestic production of high-efficiency heat pump technology.
The Kentucky investment serves multiple strategic objectives: it reduces supply chain risk from Asia-concentrated production, qualifies for U.S. government incentives supporting domestic clean energy manufacturing, and positions the company to serve the rapidly growing U.S. heat pump market as electrification accelerates.
Innovation Leadership
The company maintains substantial R&D investment. In 2023, the World Intellectual Property Organization (WIPO) ranked Mitsubishi Electric's number of patent applications published under the PCT System as 4th in the world, with 2,152 patent applications.
For investors, these capital allocation decisions reveal management priorities: power semiconductors for electrification, energy infrastructure for grid modernization, and HVAC localization for market access and policy compliance. All three bets align with decarbonization mega-trends, suggesting coherent long-term positioning.
X. Porter's 5 Forces & Hamilton's 7 Powers Analysis
Porter's 5 Forces
Threat of New Entrants: LOW-MEDIUM
Barriers to entry remain substantial across Mitsubishi Electric's core segments. The extensive IP portfolio (4th globally in PCT applications) creates technology moats. High capital requirements for manufacturing at scale—the new SiC facility alone cost $680 million—deter casual entrants. Established relationships with railways, utilities, and building developers create sticky customer bases. Competition in these markets to sell automation systems is fierce, with Chinese robot makers a rising force in the industry. "The challenge is that everyone sees the same opportunity. Everyone sees India and Southeast Asia." Mitsubishi Electric "needs to improve its products and streamline its costs to make sure it is competitive against Siemens and ABB in those markets."
Bargaining Power of Suppliers: MEDIUM
Semiconductor supply chain dependencies create vulnerability. Rare earth materials for motors and electronics face concentrated supply. However, Mitsubishi Electric mitigates through vertical integration (the new SiC facility produces its own wafers) and multiple supplier relationships developed over decades.
Bargaining Power of Buyers: MEDIUM-HIGH
Large infrastructure customers—railways, utilities, major developers—wield significant negotiating power. Long procurement cycles with government entities mean delayed decisions and price pressure. Consumer segments (HVAC, home appliances) show more fragmented buyer bases with correspondingly less individual buyer power.
Threat of Substitutes: LOW-MEDIUM
Factory automation becomes increasingly essential as labor costs rise—it's not substitutable so much as deferrable. HVAC systems are necessity products in modern buildings. Some elevator/escalator competition exists from newer technologies, but installed base creates switching costs. Energy systems face transition risks as renewables grow—but Mitsubishi Electric positions in both legacy and renewable segments.
Industry Rivalry: HIGH
Competition intensity varies by segment. The key players in the factory automation market include ABB, Emerson Electric Co., Mitsubishi Electric Corporation, General Electric, Rockwell Automation, Inc., Omron Corporation, Honeywell International Inc., Schneider Electric SE, Siemens AG, Yokogawa Electric, Fanuc Corporation.
The global Elevator and Escalator Market is highly competitive, with key players including Mitsubishi Electric Corporation, Otis Elevator Company, Schindler Holding Ltd., Thyssenkrupp AG, KONE, Hitachi Ltd.
The Air Conditioning Equipment Market is expected to reach USD 125.71 billion in 2025. Daikin Industries, Ltd., Hitachi Ltd., Johnson Controls, Electrolux AB Corporation and Mitsubishi Electric Corporation are the major companies operating in this market.
Hamilton's 7 Powers
Scale Economies: STRONG
Employee count increased from 109,565 in 2010 to 149,134 in 2024. Global manufacturing footprint provides production cost advantages, particularly in Japan and Asia where labor and supply chain efficiencies compound. R&D spending spreads across multiple high-margin business lines, amortizing innovation costs.
Network Economies: MODERATE (GROWING)
Factory automation ecosystems create switching costs—once a customer deploys Mitsubishi PLCs, they're embedded in processes and trained staff. Integrated solutions across building systems (elevators, escalators, HVAC, building management) create interdependencies. The "Serendie" digital platform aims to strengthen network effects through IoT connectivity.
Counter-Positioning: MODERATE
The transformation to "Circular Digital-Engineering" represents potential counter-positioning against purely hardware-focused competitors. Sustainability focus differentiates from price-driven competitors. Environmental Plan 2025 aims for net-zero GHG emissions at factories and offices by March 31, 2031, and across its value chain by March 31, 2051.
Switching Costs: HIGH
Factory automation PLCs embed deeply in customer manufacturing processes—replacing them requires recoding, retraining, and risking production disruption. Train systems and infrastructure equipment have multi-decade lifecycles; once installed, they're rarely replaced before end-of-life. Elevator/escalator service contracts create long-term relationships that renew automatically absent explicit cancellation.
Branding: MODERATE-STRONG (RECOVERING)
The Mitsubishi brand carries trust in Japan and globally, though the quality scandal damaged this asset. Industrial B2B branding rests on reliability and technology leadership—attributes under reconstruction. Consumer branding in HVAC segments benefits from decades of product presence and service network investment. Recovery is in progress post-scandal, but full restoration requires years of clean execution.
Cornered Resource: MODERATE
Mitsubishi Electric provides the world's only spiral escalators. This monopoly position in spiral escalators, while a small segment, represents genuine cornered resource. Leading positions in certain power semiconductor technologies create capability advantages. Space and defense capabilities operate in restricted markets with limited competition.
Process Power: MODERATE
Decades of manufacturing expertise, particularly in precision equipment for demanding applications (satellites, high-speed elevators, power semiconductors), create process advantages difficult to replicate. The Westinghouse partnership from 1923 onward built foundational capabilities that successive generations of engineers refined.
Key KPIs to Track
For long-term fundamental investors, two metrics matter most for monitoring Mitsubishi Electric's ongoing performance:
1. Operating Profit Margin (OPM)
Management has set FY2025 financial targets including 10% operating profit margin. In FY25, operating profit reached ¥391.8 billion on revenue of ¥5,521.7 billion—implying approximately 7.1% OPM. The gap between current performance and the 10% target measures progress on margin improvement initiatives. This metric captures both revenue quality (mix shift toward higher-margin segments) and cost efficiency (automation of operations, supply chain optimization).
2. Overseas Revenue Ratio
The ratio of overseas revenue to consolidated revenue was 51.3% in FY2024. This metric matters because it indicates geographic diversification away from the mature Japanese market. Growth in overseas revenue—particularly in the U.S. and emerging Asian markets—signals successful execution of global expansion strategies. Currency effects complicate interpretation, so tracking both nominal and constant-currency trends provides fuller insight.
These two KPIs—margin improvement and geographic expansion—capture the essence of Mitsubishi Electric's strategic transformation: becoming more profitable and more global simultaneously.
Bull Case vs. Bear Case
The Bull Case
Mitsubishi Electric sits at the intersection of three structural mega-trends: electrification, automation, and decarbonization. Factory automation demand accelerates as labor costs rise globally and manufacturers seek productivity gains. HVAC demand grows as climate change intensifies and heat pumps replace fossil-fuel heating systems. Power semiconductor demand expands as electric vehicles and renewable energy installations multiply.
The company's diversification provides multiple avenues for growth without excessive concentration risk. Unlike pure-play competitors vulnerable to single-segment downturns, Mitsubishi Electric can offset weakness in one area with strength in others. The Friday Club relationships within the Mitsubishi keiretsu provide preferential access to contracts and information that outside competitors can't match.
Post-scandal governance reforms—majority outside directors, enhanced quality control systems, cultural change initiatives—address the root causes of past failures. Record financial results in FY2024 and FY2025 demonstrate execution capability. Strategic investments in SiC semiconductors, U.S. manufacturing, and digital platforms position the company for future growth.
The valuation provides margin of safety. The stock trades at levels that don't fully reflect the company's market positions, recurring revenue characteristics, and growth potential.
The Bear Case
The quality scandal revealed cultural problems that may persist despite governance reforms. Siloed organizations don't transform quickly—the same dynamics that enabled three decades of fraud continue operating beneath surface changes. The Friday Club relationships that provide advantages also create insularity and resistance to outside perspectives.
Competition intensifies from all directions. Chinese robot makers are a rising force in the industry. Everyone sees the same opportunities in India and Southeast Asia. Siemens, ABB, Rockwell, and FANUC compete aggressively in factory automation. Daikin dominates HVAC globally. Otis leads elevators. In each segment, Mitsubishi Electric faces well-resourced competitors with comparable technology.
The semiconductor investment carries execution risk. The company has postponed parts of its equipment enhancement plan for the new SiC facility to fiscal 2031 and beyond, due to a slower-than-expected increase in demand in the EV market. If EV adoption disappoints further, the SiC investment becomes a burden rather than a growth engine.
Currency exposure creates earnings volatility. A strengthening yen—management's assumption for FY26—compresses overseas revenue when translated back to yen, offsetting operating improvements.
The automotive equipment segment faces structural challenges as the industry transitions to electric vehicles. Legacy Tier 1 suppliers like Mitsubishi Electric Mobility must transform or become obsolete—and transformation requires capital that dilutes returns from other segments.
Conclusion: The 100-Year Arc
From a marine electric motor factory in 1921 Kobe to a global conglomerate spanning satellites and spiral escalators, Mitsubishi Electric's century-long journey mirrors Japan's own industrial transformation. The company inherited the zaibatsu DNA of government relationships, vertical integration, and diversification. It survived postwar dissolution, rode the economic miracle, and built world-leading positions in multiple industrial niches.
But the quality scandal revealed the shadow side of this heritage: siloed operations that enabled decades of fraud, governance structures that failed to surface problems, and cultural dynamics that prioritized delivery over quality. The company's response—new leadership, governance reforms, cultural change initiatives—addresses symptoms but may not cure underlying conditions.
For investors, Mitsubishi Electric presents a classic transformation narrative. The strategic logic is compelling: position in growing markets (automation, electrification, decarbonization), leverage scale and technology advantages, and expand globally while defending Japanese strongholds. Financial results demonstrate execution. But the fundamental question—whether cultural change runs deep enough to prevent future scandals—may take years to answer.
The diversified portfolio provides stability but limits explosive growth. The company won't become the next high-growth darling, but it may compound steadily for decades as electrification and automation trends unfold. For patient investors with long horizons, the combination of market position, strategic investments, and transformation potential may offer attractive risk-adjusted returns.
The next chapter of the Mitsubishi Electric story depends on execution: can the company translate strategic vision into sustained performance? Can governance reforms prevent recurrence of quality failures? Can the digital transformation create genuine competitive advantages? The answers will determine whether the next century matches the first.
