Casio Computer Co., Ltd., founded in 1946 in Tokyo, Japan, has evolved into one of the most recognizable names in consumer electronics, celebrated for its pioneering advancements in calculators, digital watches, and electronic musical instruments. The brand holds a nostalgic appeal for Generation X and Baby Boomers who remember its dominance in the 1970s and 1980s, while also enjoying a resurgence as a trendy retro brand, particularly embraced by Generation Z.
According to MacroTrends, as of October 4, 2024, Casio’s market capitalization stands at approximately $1.92 billion, reflecting the company’s solid financial performance and market valuation.
Founding and Vision
As mentioned by Casio World, the brand was founded by Tadao Kashio, a Japanese engineer, in 1946, shortly after World War II. Kashio’s vision was to innovate and improve everyday life through accessible technology. Casio’s first product was not a calculator or watch but surprisingly a “Yubiwa Pipe,” a ring that allowed users to hold a cigarette hands-free, which became popular in post-war Japan.
Introduction of Calculators
In 1957, Casio introduced the world’s first fully electric compact calculator, the Model 14-A. This innovation set Casio apart from other brands, establishing it as a leader in precision instruments. The calculator was groundbreaking due to its ability to perform the four basic arithmetic operations (addition, subtraction, multiplication, and division) electronically, a significant step forward in a time when mechanical calculators were the norm. And who didn’t see one of these at home or in the office?

The Digital Watch Revolution
Casio’s Entry into Timepieces
In the 1970s, Casio ventured into the watch industry. At a time when Swiss watches dominated the market, Casio’s affordable digital timepieces disrupted the status quo. In 1974, Casio released the Casiotron, the first digital watch with an automatic calendar function. Unlike analog watches, the Casiotron used quartz technology, which was more accurate and easier to maintain.
The G-Shock Phenomenon
One of Casio’s most iconic creations is the G-Shock series, launched in 1983. Engineer Kikuo Ibe designed the G-Shock to be the most durable watch ever, resistant to shocks, vibrations, and water. Initially targeted at sports enthusiasts, the G-Shock quickly gained popularity across various demographics, including law enforcement and military personnel. The G-Shock’s success is attributed to its “Triple 10” concept—10 meters of free-fall endurance, 10 bar water resistance, and 10-year battery life—making it a go-to for individuals requiring rugged performance.

Casio continued to innovate with watch models that included functions beyond time-telling. In 1995, Casio released the first watch equipped with GPS, and in the following years, introduced models with features like temperature, altitude, and barometric readings.
Casio also developed solar-powered models, contributing to eco-friendly technology in the watch industry.
Calculators: Building Blocks of Casio’s Legacy
Casio’s success in calculators didn’t stop with its first model. Over the decades, Casio has introduced a wide range of calculators designed for students, professionals, and industries. The FX series, known for its scientific calculators, became a staple in education, helping Casio gain a strong foothold in schools and universities worldwide. The FX-82 and FX-991 models are particularly notable for their affordability and reliability, becoming tools of choice for students tackling complex mathematical equations.
Casio also revolutionized financial calculations by introducing specialized calculators for accounting and finance professionals. The development of programmable calculators and graphical calculators in the 1980s and 1990s solidified Casio’s reputation as a leader in educational tools.
Digital and Electronic Musical Instruments
In 1980, Casio entered the music industry by releasing the Casiotone 201, its first electronic keyboard. Casio’s musical instruments became popular for their affordability and ease of use. Casio’s keyboards appealed to beginners and seasoned musicians looking for portable, versatile tools. The Privia series of digital pianos has received acclaim for its authentic piano sound, realistic feel, and affordability, making it a favorite among music educators and learners.
In addition to keyboards, Casio developed sound samplers, which were used in some of the earliest forms of electronic music production. Casio’s affordability helped democratize music production, allowing aspiring musicians to create music without the need for expensive equipment.

Contributions to the Camera Industry
In the early 1990s, Casio entered the digital camera market with the QV-10, the first digital camera with an LCD screen. This innovation marked a shift in the digital photography landscape, making Casio a pioneer in portable digital cameras. The QV-10 allowed users to preview their photos instantly, a feature now standard in digital cameras and smartphones.
Casio continued to push boundaries with high-speed photography, producing models capable of taking up to 1,000 frames per second. Although Casio eventually exited the camera market in 2018 due to intense competition, its early contributions left a lasting impact on the industry.
Brand Identity and Market Position
Casio has established a lasting reputation in the electronics market with products that embody durability, affordability, and innovation. Known for its alarm clocks, its iconic G-Shock and Edifice watches and widely used calculators, Casio appeals to a broad audience, including tech-savvy, environmentally conscious consumers.
The brand’s commitment to reliability and sustainability—seen in solar-powered watches and long-lasting calculators—aligns with growing demand for eco-friendly products. Casio’s influence extends beyond function into culture, with the G-Shock and F-91W digital watches embraced as style symbols worldwide.
From its roots as a post-war startup to a global electronics leader, Casio remains dedicated to creating reliable, innovative products that stand the test of time.
