Casio's Yamagata factory in Japan 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 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. A third-party report from Worn and Wound (August 2025) confirms that the A159 was previously hand-assembled and that Casio automated the assembly process in 2018, reducing cost by 50%. Hypebeast (August 2025) characterizes the factory as 'strategically integrating AI' into manufacturing. 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 classified as Reported because the AI characterization comes from third-party sources rather than Casio's own disclosures.
