CASIO JAPAN DESIGN
Count on Casio calculators now and forever. For 60 years, Casio pocket calculators have been easy to read, easy to use and durable. Today, however, we are redesigning their core identity from scratch to create a new future for computing.
The History of Casio Calculators
Casio Computer Co., Ltd. was founded by the four Kashio brothers (Tadao, Toshio, Kazuo, and Yukio) in 1957. That same year, led by eldest brother Toshio, the company developed the "14-A", the world’s first fully electric compact calculator — operating solely on electric circuits rather than gears or motors.
The brothers combined their respective strengths to grow the company while living by their ideals of "creativity and contribution." Starting in 1965, 2025 marks the 60th anniversary of the "001," the world’s first electronic desktop calculator with memory functions. Let’s retrace this long and remarkable history:
