Seiko Epson Halts Production at Hokkaido Plant Following Earthquake
Wednesday, December 10, 2025 at 04:34 AM
Seiko Epson temporarily suspended operations at its Chitose plant in Hokkaido, which manufactures projector components, to conduct equipment inspections following a seismic event, as reported by Nikkei. The tweet also raised a question about the status of Rapidus's nearby pilot line.
Context
Seiko Epson Corporation has temporarily halted production at its Chitose (Hokkaido) plant starting December 9, following an earthquake that registered a seismic intensity of 6+ near Hachinohe on the night of December 8. The suspension is for equipment inspections to ensure precision manufacturing of high-temperature polysilicon TFT LCD panels, which are critical components for projectors produced at this facility. This action underscores the vulnerability of high-tech manufacturing to natural disasters.
While the immediate impact on supply chains is assessed as limited, this event highlights potential vulnerabilities in semiconductor and display component manufacturing. Epson maintains alternate production capabilities at its Suwa Minami site and possesses existing inventories, mitigating immediate supply disruptions. Investors should monitor the duration of the production halt and any potential ripple effects on the broader supply chain, though no confirmed impact on other lines, such as Rapidus pilot/back-end lines, has been reported.
