, Tokyo in 1949, Kashio and his younger brothers (Toshio, Kazuo, and Yukio) used their profits from the yubiwa pipe to develop their calculators. Most of the calculators at that time worked using gears and could be operated by hand using a crank or using a motor (see

s. After dozens of prototypes were tested, the desk-sized calculator was finished in 1954 and was Japan's first electro-mechanical calculator. One of the central and more important innovations of the calculator was its adoption of the 10-key number pad; at that time other calculators were using a "full keypad", which meant that each place in the number (1s, 10s, 100s, etc. ...) had nine keys. Another distinguishing innovation was the use of a single display window instead of the three display windows (one for each argument and one for the answer) used in other calculators. Casio Computer Co., Ltd. was formed in June 1957. That year, Casio released the Model 14-A, sold for 485,000

In the 1980s, Casio's budget electronic instruments and its line of affordable home electronic Keyboard instrument, musical keyboard instruments became popular. The company also became well known for the wide variety and innovation of its wristwatches. It was one of the earliest manufacturers of Quartz clock, quartz watches, both digital and analog. It also began selling calculator watches during this time. Casio also introduced one of the first watches that could display the time in many different time zones of the world and with features like recording temperature, atmospheric-pressure and altitude. In the later years, Casio's wristwatches were fitted with receivers to synchronise with radio towers around the world and Global Positioning System for timekeeping accuracy. A number of notable digital camera innovations have also been made by Casio, including the QV-10, the first consumer digital camera with a liquid-crystal display (LCD) on the back (developed by a team led by Hiroyuki Suetaka in 1995), the first consumer three-megapixel camera, the first true ultra-compact model, and the first digital camera to incorporate ceramic lens technology, using Lumicera. In July 2019, the company's UK arm, Casio Electronics Co. Ltd, was fined £3.7 million after admitting resale price maintenance (a form of price-fixing) on their line of digital keyboards and digital pianos between 2013 and 2018, in breach of the United Kingdom's Competition Act 1998.
