Where it all started
The Four Kashio Brothers
The unique strengths of four people, united as one
Casio was founded by the four Kashio brothers: Tadao, Toshio, Kazuo, and Yukio.
Led by the second eldest, Toshio, the four brothers developed the 14-A, the world’s first compact all-electric calculator, and established Casio Computer Co., Ltd. in 1957. Each brother brought his unique specialty and strength: Tadao in finance, Toshio in development, Kazuo in sales, and Yukio in production. Taking on a specific role and working closely to complement each other, the brothers grew the new company together.
Origin of the CASIO company emblem
The company emblem is a design that encompasses and highlights the Casio trademark with a circle of four Ks, the initial letter in Kashio. The emblem symbolizes the strong ties among the four Kashio brothers that founded and developed their calculator business. Toshio Kashio, inventor of the Casio calculator, designed the emblem himself to embody their approach to the business.
Casio Philosophy
Casio's corporate creed is "creativity and contribution." It expresses the company's commitment to contributing to society by offering the kind of original, useful products that only Casio can.
Products with innovative functions assist people in their daily lives and keep society moving forward. They also bring joy to people and help to create a new culture. When even a single new product is widely adopted, whole new markets develop, and this, in turn, fosters growth in related industries. This is the story of Casio's contribution to society-innovative products enhancing people's lives.
