Casio

What started as a tiny workshop in post-war Japan has grown into a global electronics powerhouse. The Kashio brothers, led by Tadao, turned their mechanical ingenuity into the world's first compact all-electric calculator, the 14-A, back in 1957. That single device set the stage for decades of innovation, moving the company from office tools to the gadgets that define daily life.

Today, the Timepieces division drives the business forward, raking in over 184 billion yen of the company's total 276 billion yen sales for the fiscal year ending March 31, 2026. This success rests on a diverse lineup including G-SHOCK, BABY-G, and EDIFICE, which compete directly with Swiss luxury houses and tech giants like Apple. The brand balances its heritage with modern demands, recently launching the F-B100W to bring step counting to a classic silhouette.

Casio maintains a strong presence across Japan, the US, Europe, and Asia, distributing products through major retailers like Best Buy and Jomashop. Their community engagement runs deep, often celebrating enthusiast projects like running BBS systems on vintage calculators. While some critics point to frequent re-releases or plastic durability concerns, the company continues to prioritize reliability and accessible pricing without any major scandals disrupting its stability.
