Company history

Mitsubishi Electric did not begin as a startup reaching for an outside market; it was carved out of the Mitsubishi zaibatsu. Electric-machinery work had started in 1905 inside the Kobe shipyard of Mitsubishi’s shipbuilding arm — the yard completed Japan’s first domestically built turbine generator in 1908 — and in January 1921 that electrical division was spun off as an independent company, Mitsubishi Electric. Its first assets were the technology and the captive demand it inherited from within the group.

From a new Kobe Works it started with the basics — transformers, motors, electric fans — then widened fast: a Nagasaki plant in 1923 for turbine generators and marine machinery, and a Nagoya works in 1924 for standard motors and home appliances. Across those three sites the company set, from its earliest years, the shape it would keep — a heavy-electric core for the Mitsubishi group that also kept one foot in consumer goods.

War demand then swelled it quickly. Through the first half of the 1940s Mitsubishi Electric threw up plant after plant — Osaka (today’s Itami) in 1940, four works in 1943 alone, Himeji in 1944 — dispersing production into the provinces until it held more than ten domestic works, and in 1944 it raised its head-office research section to a full laboratory. The company that would rebuild after the war as a full-line electrical maker was, in outline, already there.

The postwar breakup of the zaibatsu forced Mitsubishi Electric to stand on its own. It listed on the Tokyo Stock Exchange in May 1949, revived its technical and capital tie-up with Westinghouse — royalties in exchange for years of accumulated American know-how, judged well worth the cost in quality and price — and turned toward civilian demand, opening a radio-equipment works in 1953 and a refrigerator-and-air-conditioner plant in 1954.

Electronics was then layered onto the heavy-electric base. A dedicated semiconductor mass-production plant opened at Kitaitami in 1959, on the back of the power utilities’ generating boom, and the Kamakura Works followed in 1960 for radio, electronics and computers. In 1973 the company set up Mitsubishi Electric America and began building an overseas sales network directly. Yet when the long electrification boom ended in the mid-1960s, earnings drifted into decline, and the trade press chided the firm for a complacent, “lordly” style of management.

In 1977 Mitsubishi Electric adopted a business-headquarters (division) system — four HQs for heavy-electric, electronics, equipment and products — and pushed abroad (Singapore in 1977, Taiwan in 1978), so that overseas growth and a domestic culture of vertical, silo-by-silo management took shape at the same time. With heavy-electric demand at home stalled after the oil shock, Middle Eastern plant exports carried the load, reaching $380.8M (¥111bn) of orders in 1976; but electronics stayed weak, and the company’s chips drew the withering verdict that “Mitsubishi’s semiconductors are nothing to worry about.” By 1983 the four HQs had become six, and its place among Japan’s electrical majors was set.

Through the late 1980s and early 1990s the silos multiplied. Car electronics — navigation, engine control, alternators — was raised to its own business headquarters in 1989, and by 1993 the company ran nine business HQs in all, the vertical structure of a full-line maker at its widest. That nine-HQ shape would remain the basic form of the organization for the next three decades.

The counter-current was selection and concentration. In 1994 President Kitaoka Takashi invoked Jack Welch’s GE — make every business first-class or cut it, and “50,000 people on $24.5B (¥2.5tn) of sales is too extravagant” — and pressed to trim both businesses and headcount. In 1998 the company quit commodity DRAM, stepping off a pure cost race that Nikkei called the start of Japan’s semiconductor “age of selection.” Consolidated revenue nonetheless reached $29.1B (¥3.65tn) by the year to March 2002.

The pivot was then made explicit. In 2001 the group adopted the statement “Changes for the Better,” and in 2003 it became one of the earliest of Japan’s majors to move to committee-based governance, forming the industrial-systems venture TMEIC with Toshiba the same year and shifting its chip business from commodity memory toward power, high-frequency and optical devices. A run of emerging-market sales companies (India in 2010 through Russia in 2014) and the 2016 purchase of Italy’s DelClima carried it back to $38.3B (¥4.05tn) of revenue and $2.2B (¥235bn) of operating profit by the year to March 2014 — even as the works-based silos survived every reorganization intact.

In 2021 the silos exacted their price. At the Nagasaki Works, performance inspections of rail-car air-conditioning and other products were found to have been recorded for years against fabricated data. President Sugiyama Takeshi resigned that July, and senior executive vice-president Urutsuma Kei was elevated over more obvious candidates. He placed the cause not in faulty procedure but in a missing “sincerity toward quality” — an organization that would not surface inconvenient facts — and stood up a quality-reform headquarters in October. It was a heavy blow to a major’s earnings base, and it laid the company’s governance weakness bare.

Reorganization followed at speed. In 2022 the firm collapsed its many HQs into four Business Areas — Infrastructure, Industry & Mobility, Life, and Business Platform — and in 2023 pulled the semiconductor business back out of that structure to report directly to the CEO, while renaming its electronics-systems HQ “Defense & Space” and pouring investment into it. In 2024 it spun the car-equipment business off as Mitsubishi Electric Mobility. Revenue climbed from $35.6B (¥5tn) in the year to March 2023 to $36.9B (¥5.52tn) two years later, a succession of records.

The recovery became a platform for something more deliberate. Operating profit hit a record $2.6B (¥392bn) in the year to March 2025, and at an IR Day that May, CEO Urutsuma set out a turn toward a “circular digital-engineering company” built on a digital platform called Serendie, tagged some $12.7B (¥1.9tn) of businesses as “value-recapture” candidates to wind down or fix, framed a three-year $6.7B (¥1tn) envelope for acquisitions, and committed to a total-return ratio above 50% and a record $668.2M (¥100bn) buyback. A company long known for cautious, stability-first management was, plainly, choosing to institutionalize both structural change and shareholder returns.
