Toshiba

Toshiba Corporation is a Japanese multinational conglomerate headquartered in Tokyo. It traces its origins to 1875 with Tanaka Seisakusho, founded by Hisashige Tanaka, and later became Tokyo Shibaura Denki K.K. after a 1939 merger of Tanaka's company with Shibaura Seisaku-sho. The name Toshiba is a shortened form of Tokyo Shibaura Electric Co., Ltd. The company is one of Japan's oldest and most diversified electronics manufacturers.

Toshiba's operations span several business areas, including Infrastructure (power generation, transmission and distribution equipment, industrial systems), Electronic Devices (semiconductors and memory, sensors, displays), and Digital Solutions (IT services and software) with a global customer base. In memory, Toshiba Memory was spun off and sold to Bain Capital and became Kioxia in 2019. Toshiba Medical Systems, a medical-imaging unit, was sold to Canon and renamed Canon Medical Systems.

In the corporate history, Toshiba built a large portfolio of consumer electronics and industrial equipment and was a pioneer in nuclear energy through Westinghouse Electric Company, a U.S. subsidiary acquired in the 1960s. Westinghouse filed for bankruptcy in 2017 after cost overruns on nuclear projects, prompting restructuring within Toshiba. The company has since focused on core infrastructure and energy-related businesses and divested non-core assets.

Toshiba is a publicly traded corporation listed on the Tokyo Stock Exchange (and has had historical ADR listings). It maintains operations worldwide and remains one of the major legacy conglomerates of Japan, with ongoing emphasis on engineering and technology across its remaining segments.
