Do we like Casio?
Makes watches (G-SHOCK), calculators, digital pianos and gadgets; based in Tokyo, Japan.
Our score: 6 out of 10. A solid, long-running maker of durable products with no major scandals. A 2024 data breach and thin evidence on its wider conduct keep us from a higher score.
Casio is the Japanese company behind G-SHOCK watches, calculators and digital pianos. The Kashio family has run it for decades. The sustainability reports we found list Kazuo Kashio as CEO and Kazuhiro Kashio as President and COO in 2015. We couldn't confirm who holds those jobs now.
The big drama was in October 2024. Casio said it spotted an intrusion on 5 October that caused system failures. The Underground ransomware group claimed it had taken 204.9 GB of data. Casio later confirmed that data on about 8,500 people, mostly employees, was stolen.
Casio's investigation pointed to phishing emails and weaknesses at overseas offices. It said the customer database and credit card data were not affected. It reported the incident to Japan's Personal Information Protection Commission and said it hadn't given in to the attackers' demands. That's a fair response, but the security gaps were real.
On the environment, Casio set up its Environmental Vision 2050 in 2012. Its 2017 report set group-wide greenhouse gas targets of 26% less by fiscal 2031 and 80% less by fiscal 2051, against a fiscal 2014 baseline. Those are the company's own pledges, and we saw no recent independent check of them.
Results for the year to March 2026 showed a higher profit, and a new three-year plan is under way. It's a steady company rather than a standout. We'd back it, but without much excitement.
