Mizuno Corporation was founded in 1906 in Osaka by Rihachi Mizuno and his younger brother Rizo. The shop sold western products including baseball equipment. A year later it became a real sports brand. Mizuno began to sell order-made sportswear.

In 1910, the two brothers moved the shop to Umeda-Shinmichi. This is a commercial district in Osaka with many shops. The shop was named 'Mizuno Shop'. In 1913, the brand started to design and produce their own baseballs and baseball gloves.
