Kumamoto Prefecture in Japan, home to the world's largest semiconductor contract manufacturer TSMC and dreaming of becoming a "semiconductor capital," has suffered massive damage from a major earthquake that struck for the first time in 10 years, resulting in 36 deaths, over 9,000 displaced persons, and the suspension of TSMC factory operations.
The Kikuyomachi area in Kumamoto Prefecture, Japan, was deeply scarred by a major earthquake that occurred before August 1, 2026. This region, once rapidly developing as a "Silicon Island" during the semiconductor boom, now faces disaster with 36 deaths recorded and over 9,000 displaced persons living in evacuation centers.
TSMC's Kumamoto Plant 1, the world's largest semiconductor company, has completely halted operations following the major earthquake for equipment inspections. Plant 2, which was under construction nearby, was temporarily suspended but is showing signs of resuming. This presents a potential threat that could trigger a domino effect in the global semiconductor market and emerges as a factor that could increase instability in the global semiconductor supply chain.
The aftermath of the earthquake has not only impacted factories but also dealt a direct blow to nearby commercial districts. Jo, a home-style restaurant owner in Kikuyomachi, lamented the sharp decline in sales, stating "my usually full restaurant is now empty and I may have to throw away ingredients due to reservation cancellations," pointing to the empty factory parking lot and sparse lunch-hour commercial activity.
