Foundation (1946–1957)

The origins of Casio trace back to 1946, when engineer Tadao Kashio founded Kashio Seisakujo in Tokyo following the Second World War. The enterprise initially produced mechanical components and small devices. Among its earliest commercial successes was the Yubiwa Pipe, a finger-mounted cigarette holder that gained popularity in post-war Japan.

Recognising the increasing significance of automation, Kashio and his brothers redirected their efforts towards calculating machines. After several years of research, the firm introduced Japan’s first compact all-electric calculator. In 1957, the business was officially incorporated as Casio Computer Co., Ltd. and launched the Casio Model 14-A, regarded as one of the world’s first compact fully electric calculators.

Calculators

Casio transformed electronic calculation by manufacturing calculators that were smaller, more affordable, and widely accessible. Key milestones in this sector include:

• Japan’s first compact electric calculator
• The first personal calculators designed for consumers
• Scientific calculators tailored for education
• Graphing calculators for engineering and mathematics
• Financial calculators for professional use

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

Digital Watches

Casio entered the wristwatch market in 1974 with the Casiotron, one of the first digital watches capable of automatically adjusting for varying month lengths. The company subsequently released several iconic product families:

• G-Shock: Characterised by extreme durability and shock resistance
• Baby-G: A compact variant of the G-Shock line
• Edifice: Analogue watches inspired by motorsports
• Pro Trek: Timepieces designed for outdoor adventure
• Oceanus: Premium solar-powered radio-controlled watches
• Classic Collection: Affordable digital models such as the F-91W and A168

Casio timepieces became synonymous with reliability, extended battery life, and value for money.

G-Shock

Launched in 1983, the G-Shock series revolutionised the watch industry. Developed by engineer Kikuo Ibe, the timepiece was engineered around the “Triple 10” concept:

• 10-metre drop resistance
• 10-bar water resistance
• 10-year battery life

The G-Shock remains widely utilised by military personnel, athletes, emergency responders, and outdoor enthusiasts.

Electronic Musical Instruments

Casio expanded into the music industry in 1980 with the introduction of electronic keyboards. Notable product lines include:

• Casiotone
• Privia digital pianos
• Celviano digital pianos
• CT-X arranger keyboards
• SA mini keyboards

These instruments are valued for their affordability and beginner-friendly features, whilst also catering to advanced musicians.

Digital Cameras

Throughout the 1990s and 2000s, Casio was a significant innovator in digital photography. The Exilim series was distinguished by slim designs, high-speed photography and video recording capabilities, and user-friendly interfaces. Casio eventually exited the digital camera market as smartphone photography became dominant.

Education

Casio has consistently supported the education sector through products including scientific and graphing calculators, classroom software, educational apps, and examination-approved devices. Many schools and examination boards internationally recommend or mandate the use of Casio calculators.
