Overview
- The Japan Meteorological Agency issued a Level‑5 landslide special warning for Yakushima Town on Saturday, saying some disasters are likely already occurring and urging residents to secure their safety immediately.
- Forecasters said intermittent line‑shaped heavy‑rain bands linked to Typhoon No.24 and a stalled Pacific front produced extreme localized rainfall on Yakushima.
- Local observations cited by authorities include about 548 mm of rain over 48 hours at Onoama and a maximum instantaneous wind gust of 25.9 m/s, measurements that underpinned the highest alert level.
- The national government raised its crisis coordination by upgrading the Prime Minister's Office contact room to a cabinet liaison room and warned that southern Kyushu and Pacific coastal prefectures face continued heavy rain through Sept. 6–8 with 24‑hour totals forecast up to around 200 mm in some areas.
- A Level‑5 special warning in Japan means lives are at immediate risk and calls for urgent protective action such as evacuation or moving to a safe, elevated location because landslides and flash flooding may already be happening.
