A powerful earthquake measuring a preliminary magnitude of 6.2 struck Japan’s western Chugoku region on Tuesday morning, according to the Japan Meteorological Agency (JMA). The main tremor occurred at around 10:18 a.m., with the epicenter located in Shimane Prefecture. Authorities confirmed that there was no risk of a tsunami.
The quake was followed by several aftershocks, including a strong magnitude 5.4 tremor recorded at approximately 10:37 a.m.
Chugoku Electric Power, which operates the Shimane Nuclear Power Station located about 32 kilometers from the epicenter, reported no abnormalities at the facility. Japan’s Nuclear Regulation Authority also confirmed that no irregularities were detected. A spokesperson said inspections were underway to assess any possible impact on the plant’s No. 2 reactor, which resumed operations in December 2024 after being shut down in the aftermath of the 2011 Fukushima disaster.
Meanwhile, West Japan Railway temporarily suspended bullet train services between Shin-Osaka and Hakata as a safety precaution following the earthquake. Rail operations were later fully restored by 1:00 p.m.
Authorities continue to monitor the situation as aftershocks subside.
