Strong Earthquake Shakes Central Japan, Disrupts Transport and Injures at Least 22

A strong earthquake struck central Japan early Sunday, causing property damage, transportation slowdowns, and leaving at least 22 people injured, according to local media reports.

Japan's Meteorological Agency measured the quake at a magnitude of 5.7, while the US Geological Survey reported it at a magnitude of 5.5. A series of smaller aftershocks followed the initial tremor, which struck at 1:04 am at a depth of about 40 kilometres below the earth's surface in Shizuoka Prefecture.

The seismic event affected a wide area near Aichi Prefecture, including the city of Hamamatsu, the ancient capitals of Kyoto and Nara, and nearby prefectures such as Yamanashi—where Mount Fuji is located—and Gifu. Official seismic assessments indicated that the most violent shaking was felt in Aichi. Because Aichi and Shizuoka are neighbouring regions located at a distance from Tokyo, the quake was not felt in the capital.

Television footage from the affected regions displayed shattered store windows, scattered shards of glass on streets, and commercial spaces disrupted by the tremor, such as a bookstore where mounds of books fell off the shelves. Among the 22 reported injuries were individuals who fell from stairs while attempting to flee buildings during the shaking.

As a precautionary measure, Shinkansen bullet trains operated at slower speeds across the affected areas to mitigate risks associated with potential railway damage. Meanwhile, the meteorological agency issued warnings for residents to prepare for possible strong quakes in the coming week, particularly over the next two to three days.

Ayataka Ebita, an official with the meteorological agency, advised reporters to remain vigilant regarding mudslides, falling rocks, and potential rainfall impacts. Ebita added that no apparent changes had been detected so far in the Nankai Trough plate, an area where scientists have previously noted the possibility of a megaquake.

Japan remains one of the world's most earthquake-prone regions, prompting authorities to maintain ongoing public safety guidelines instructing residents to stock emergency supplies such as bottled water, food, and batteries, maintain safety plans, and keep footwear accessible.

"Natural disasters present immediate operational challenges for businesses, supply chains, and local commerce. Incidents like the recent earthquake in central Japan underline why business continuity planning and regional risk management are critical for enterprises operating in seismically active zones. Ensuring employee safety and protecting physical infrastructure remain foundational priorities during unexpected disruptions." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
