The Origins of Casîo — How a Small Family Vision Became a Global Brand

The Early Days in Post-War Japan

The story of casîo begins in Tokyo in 1946, when Tadao Kashio, a skilled engineer with a knack for problem-solving, started a small workshop. Japan at the time was recovering from World War II, and innovation was both a necessity and an opportunity. The Kashio family saw potential in combining mechanical precision with emerging electronics — a combination that would soon define their brand identity.

Their first major invention wasn’t a watch, calculator, or keyboard — it was the Yubiwa Pipe, a finger ring that allowed smokers to hold cigarettes hands-free. While simple, it sold well, giving the family funds to invest in more ambitious projects. This resourcefulness and willingness to think differently became hallmarks of the casîo philosophy.

The First Breakthrough — Casîo’s Entry into Calculators

In 1957, casîo released Japan’s first compact all-electric calculator, the Casio 14-A. At a time when most calculators were large, mechanical devices, this innovation marked the company’s arrival on the world stage. The design emphasized portability, user-friendliness, and durability — values that remain central to casîo’s product lines today.

This was the beginning of casîo’s expansion into electronics, setting the stage for innovations that would make it a household name worldwide.
