Japan's integrated electronics industry began with Meiji-era domestic heavy electrical manufacturing, with Hitachi, Toshiba, Mitsubishi Electric, Panasonic, and Sony driving postwar high growth as the 'Big Five.' The 'comprehensive' model spanning consumer electronics, heavy electrical, semiconductors, and telecom was long considered a strength, but profitability declined from the 2000s amid Korean and Chinese competition. Toshiba fell into crisis following its 2015 accounting scandal and massive nuclear losses, going private in 2023. Hitachi staged a revival by restructuring 22 listed subsidiaries and pivoting to DX through its 'Lumada' platform. Panasonic focused on EV batteries, supplying Tesla. Sony transformed from an electronics loss-maker into a conglomerate spanning gaming, music, film, and image sensors, achieving over $7 billion in operating profit.
Founded in 1912. Personally founded by Tokuji Hayakawa, the company led technological innovation in calculators and LCD displays. Its LCD panels from the Kameyama Plant took the market by storm, but large-scale investment failures plunged it into a management crisis, leading to a recapitalization by Hon Hai Precision to pursue restructuring.
Founded in 1947. Toshio Iue left Matsushita Electric to establish the company, which grew through radios and washing machines. While the company accumulated technical expertise through concentrated investment in rechargeable batteries, the drawbacks of family management combined with financial deterioration, and in 2011 Sanyo became a wholly owned subsidiary of Panasonic.
Founded in 1946. Ibuka Masaru and Morita Akio challenged the world with transistor radios, then created culture with the Walkman and PlayStation. Through acquisitions of CBS and Columbia, the company transformed into an entertainment enterprise and continues to grow through diversified management spanning image sensors and financial services.
Founded in 1910. Starting from a repair workshop at Hitachi Mine, the company grew into a comprehensive electrical manufacturer. After struggling with unprofitable semiconductor and consumer electronics businesses, Hitachi executed structural reforms to concentrate management resources on social infrastructure and IT, and transformed into a digital enterprise through the acquisitions of GlobalLogic and ABB's power grid business.
Founded in 1918. Konosuke Matsushita started the company as an electrical appliance workshop and built a home electronics empire through the divisional system and the 'tap water philosophy.' The company integrated Sanyo Electric and Panasonic Electric Works, and focused on Tesla batteries and automotive businesses. It transitioned to a holding company structure and pursued structural reform.
