Hisashige Tanaka (1799-1881) was a clockmaker and mechanical inventor known for his karakuri automata and the Myriad Year Clock.

Hisashige Tanaka opened Tanaka Seisakusho in Tokyo in July 1875 to make telegraph equipment, the date Toshiba uses as its founding. The business later became Shibaura Seisakusho, a heavy electrical machinery maker. In 1939 it merged with Tokyo Electric, the successor to Hakunetsusha, to form Tokyo Shibaura Electric.
