Casio's Yamagata factory in Japan — where premium G-Shock watches are made — uses extensive robotic automation and a sensor-based system to detect potential equipment failures before they happen. Since 2018, one production line has been almost entirely automated, cutting production costs by 50%, according to third-party reporting. The facility also uses automated image inspection to check for assembly defects without human involvement.

The Yamagata factory produces high-end G-Shock lines including MR-G and MT-G. Its basic model production line (for the A159W) has operated without human assembly since 2018, covering soldering, screw fastening, and image-based quality inspection. For equipment health monitoring, Casio uses omnidirectional microphones fitted to robotic arms to detect unusual sounds that may indicate mechanical problems before failures occur — a form of predictive maintenance. Third-party journalism from Hypebeast (August 2025) characterizes this as "strategically integrating AI" into manufacturing. However, Casio's own official communications use the terms "automation," "Smart Factory," and "digitization" — and do not describe these systems as AI or machine learning. This practice is therefore classified as Reported, because the AI characterization comes from third-party sources rather than Casio's own disclosures.
