About Casio

Casio logo

In 1946, Tadao Kashio founded a company called Kashio Seisakujo, in Mitaka, Tokyo. One of his earliest innovations was some kind of ring that held a cigarette, allowing its wearer to smoke the cigarette until its very end – with Japan impoverished from WWII, this innovation was quite a success. Tadao Kashio, now joined by his brothers Toshio, Kazuo and Yukio, would go on and invest the proceeds … in the development of electronic calculators, of which the first prototype was shown by in 1954. In 1957 the first commercially available electronic calculator was introduced by the company, at which time Casio Computer Co., Ltd. is established.
