Which country owns Casio?

1946 – Casio Is Founded In Japan But while Casio is synonymous with watches, the company didn't actually begin life selling timepieces. Casio was founded in 1946 in Japan in the aftermath of World War II. The founder, Tadao Kashio, started out by producing mechanical parts.

hsjohnson.com - The history of Casio watches - HS Johnson

In 1600s Europe, clockmakers began experimenting and producing smaller, more portable spring-driven clocks that evolved into watches. They could be carried easily, although of course, they were very expensive, so they weren’t exactly common.

‍

Portable clocks in the form of wristwatches, but more commonly, pocket watches, became popular in the 19th century when they could finally be mass-produced and marketed. The practicality of the wristwatch became apparent, and by the 20th century, it was the most common watch on sale.

‍

The next big leap was the invention of the Quartz watch, which is the design used today by Casio watches. This was first produced properly in the early 20th century, but wouldn’t be in mass production until the 1980s. Casio was, in fact, one of the first companies to begin successfully marketing the Quartz watch.
