Casio
History
Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio (樫尾忠雄 1917–1993), an engineer specializing in fabrication technology. Kashio's first major product was the yubiwa pipe, a finger ring that would hold a cigarette, allowing the wearer to smoke the cigarette down to its nub while also leaving the wearer's hands-free. Japan was impoverished immediately following World War II, so cigarettes were valuable, and the invention was a success.
