Tezuka Productions
In 1961, Osamu Tezuka established Osamu Tezuka Mushi Production as a video and animation production unit. It was officially incorporated as Mushi Productions Co., Ltd., the following year. Tezuka served as acting director of the company until 1968, when he left to start another animation studio, Tezuka Productions Co., Ltd., as a spun-off division of Mushi Productions dedicated to manga production and copyright management.
