Production has ground to a halt in Japan’s Kumamoto prefecture following a powerful 7.1-magnitude earthquake that struck on Tuesday.

The seismic event, which has killed at least 34 people and injured dozens more, has exposed fresh vulnerabilities in the country’s manufacturing supply chains, particularly for the automotive and semiconductor sectors.

The disruption centers on an area often referred to as Japan’s 'Silicon Valley,' a critical node for chip fabrication and automotive component production.

Work stoppages in the region raise immediate concerns about potential bottlenecks for global automakers and tech firms that rely on just-in-time deliveries from Japanese suppliers.

The incident recalls the widespread industry disruptions triggered by a devastating quake in the same region a decade ago.

Markets are assessing the scale of the operational impact, with investors monitoring whether the shutdowns will extend beyond the immediate aftermath of the tremor.
