Toshiba began life in 1875 as Tanaka Seizo-sho, Japan’s first manufacturer of telegraphic equipment.
Founded by Hisashige Tanaka, the company went on to pioneering ground breaking electric and electronic products which were widely known as first of their kinds, not only in Japan but worldwide.
In 1890, Hakunetsu-sha & Co., Ltd. was established as Japan's first plant for electric incandescent lamps and evolved as a manufacturer of consumer products. In 1899, the company was renamed Tokyo Denki and in 1939, the two companies merged to form an integrated electric equipment manufacturer, Tokyo Shibaura Denki (Tokyo Shibaura Electric Co., Ltd.). The company was soon well known as 'Toshiba,' which became its official name in 1978
