Casio is a Japanese multinational electronics company best known for its calculators, watches, electronic musical instruments, digital cameras (historically), and other consumer electronics. Founded in 1946, Casio has earned a global reputation for creating durable, innovative, and affordable products. The company’s philosophy combines practical engineering with technological innovation, making it one of the world’s most recognized electronics brands.

Foundation (1946–1957)

Casio’s origins date back to 1946, when engineer Tadao Kashio established Kashio Seisakujo in Tokyo after World War II. The business initially manufactured mechanical components and small devices. One of its earliest commercial successes was the Yubiwa Pipe, a finger-mounted cigarette holder that became popular in post-war Japan.

Recognizing the growing importance of automation, Kashio and his brothers shifted their focus toward calculating machines. After years of research, the company introduced Japan’s first compact all-electric calculator.

In 1957, the company officially became Casio Computer Co., Ltd., and launched the Casio Model 14-A, considered one of the world’s first compact fully electric calculators.

Calculators

Casio revolutionized electronic calculation by making calculators smaller, cheaper, and more accessible.

Major milestones include:

• Japan’s first compact electric calculator

• First personal calculators for consumers

• Scientific calculators for education

• Graphing calculators for engineering and mathematics

• Financial calculators for professionals

Today, Casio calculators are standard equipment in schools and universities worldwide.

Digital Watches

Casio entered the wristwatch market in 1974 with the Casiotron, one of the first digital watches capable of automatically adjusting for month lengths.

The company later introduced several iconic product families:

• G-Shock — Extreme durability and shock resistance

• Baby-G — Smaller version of G-Shock

• Edifice — Motorsports-inspired analog watches

• Pro Trek — Outdoor adventure watches

• Oceanus — Premium solar radio-controlled watches

• Classic Collection — Affordable digital watches such as the F-91W and A168

Casio watches became famous for reliability, long battery life, and affordable pricing.

G-Shock

Introduced in 1983, the G-Shock series transformed the watch industry.

Developed by engineer Kikuo Ibe, the watch was designed around the “Triple 10” concept:

• 10-meter drop resistance

• 10-bar water resistance

• 10-year battery life

Today G-Shock is widely used by military personnel, athletes, emergency responders, and outdoor enthusiasts.
