7.5 Quake Halts Japan Trains, Closes Roads Amid Ongoing Tsunami Warnings

A 7.5 magnitude earthquake off Japan's northeast coast has disrupted transport with bullet trains halted and motorways closed, while tsunami warnings for up to 3-meter waves persist in Aomori, Iwate, and Hokkaido. Initial breaking reports at 08:20 GMT detailed the quake and alerts; 30 minutes later, updates confirmed the 0752 GMT event (10 km deep, upper 5 intensity), 80 cm waves detected two hours post-quake, no casualties, and stable nuclear plants. Markets face short-term volatility and downside risk for Japan 225 from infrastructure hits and risk-off flows, pending damage assessments.
