Heavy Rain Warnings Trigger Floods and Landslides Across Central Japan

Japan’s weather agency issued Level 5 heavy-rain alerts—the highest tier—in multiple north-central prefectures. On August 27 the agency warned of extreme precipitation in Ishikawa and Toyama, and on August 30 it extended a special warning to Fukui, Ono and Katsuyama. The alerts signaled that disasters were either already occurring or imminent. Torrential rain produced record-breaking totals of 300 mm in Katsuyama, Sakai and Fukui within 24 hours, and over 320 mm in Himi and Hakui, while Hodatsushimizu recorded around 230 mm. Flooded roads, submerged vehicles and landslides forced evacuations and stranded residents in mountainous areas.

Chief Cabinet Secretary Minoru Kihara warned that several rivers had overflowed and that flooding was occurring without reported injuries. The Ministry of Land, Infrastructure, Transport and Tourism considered releasing water from a dam in Sakai to increase reservoir capacity. The Japan Meteorological Agency downgraded the warning to Level 4 after rain subsided but cautioned that further rain through August 31 could sustain flood risk.
