Heavy Rain and Thunderstorms Hit Japan's Central and Eastern Regions
A widespread system of heavy rain and thunderstorms affected many parts of Japan on July 27‑28, 2026. The Kumamoto Meteorological Observatory issued thunderstorm warnings for dozens of municipalities, while the Japan Meteorological Agency warned of intense rain and hail across the Kanto‑Koshin area, forecasting up to 100 mm in a 24‑hour period on July 28‑29.
In Niigata City, a restaurant on the first floor was completely flooded, its breaker tripped and all food supplies were discarded, leaving the owner saying, "the first floor was completely flooded."
Ishikawa Prefecture issued its first‑ever Level 3 heavy‑rain warning for Kanazawa and Nanao on July 26, triggering evacuations for vulnerable residents. A lightning strike at Noto Nakajima Station caused signal failure, halting the Noto Railway for the day. The heavy rain also forced temporary road closures and resulted in two heat‑stroke cases in Kanazawa and Nomi.
Forecasts for the Kanto, Koshin and Tochigi regions warned of possible flood, river rise, landslides and hail, urging residents to stay indoors and protect crops.
