Following the recent tsunami event, Japan's nuclear facilities appear to be holding steady. The three major plants—Onagawa, Fukushima, and Higashidori—aren't showing any operational problems or safety concerns at this point. Monitoring systems across all three sites are functioning normally, with no anomalies detected in their cooling systems or structural integrity. Given the region's history with nuclear incidents, authorities are maintaining close surveillance, but early reports suggest these facilities weathered the tsunami without complications.
