Tokyo, Japan - July 10, 2025 Tokyo was hit by a torrential downpour Thursday evening during rush hour, with the Meteorological Agency warning residents to prepare for heavy rain, flooding and lightning. The agency recorded 120 millimeters of rain in Suginami Ward and about 100 mm in Setagaya Ward at around 7 p.m. — enough to cause disasters. The agency only announces warnings of this kind when there is enough rain in a short period of time to trigger landslides or flooding. Similar warnings were issued in neighboring Saitama, Kanagawa, Yamanashi, Gunma and Nagano prefectures. “Cumulonimbus clouds have developed in some places, causing torrential rain and lightning,” the agency said on its website. It warned of a “linear precipitation zone” capable of bringing localized downpours late Thursday. Such deluges could lead to disasters in the prefectures of Ibaraki, Tochigi, Gunma, Saitama, Chiba and Tokyo. The weather agency is forecasting up to 150 mm of rain in the 24 hours through 6 p.m. Friday in the Kanto region, which includes Tokyo, and 100 mm for the Koshin region of Yamanashi and Nagano prefectures.
