Brand History
Casio
Casio’s story begins with Tadao Kashio, born in 1917 in Kochi Prefecture, who later founded Kashio Seisakujo in 1946 after training as a skilled machinist. Together with his brothers, he developed inventive products such as the Yubiwa pipe before revolutionizing office technology with the 1957 release of the 14-A, the world’s first compact all-electric calculator. This milestone launched Casio Computer Co., Ltd., and set the foundation for a global legacy rooted in creativity, family, and innovation.
