A woman in her sixties has died after her car was submerged in floodwaters during severe rainfall in eastern Japan, according to Kyodo News, which cited the local fire department in Iwaki, Fukushima Prefecture. The incident happened at an underpass around 7:50 am local time on Monday. The heavy rain, which began early on Monday, affected large parts of the region, including Tokyo, Kanagawa, and Chiba prefectures, leading to disruptions in train services and the closure of some schools. In Niijima, a town about 150 kilometers south of central Tokyo, 485 mm of rain was recorded in a 24-hour period ending at 9:40 am, marking the highest rainfall amount ever recorded there. In addition to the fatality, two people suffered minor injuries after falling during the heavy rain in Chiba Prefecture, according to the local government. The Japan Meteorological Agency (JMA) issued Level 5 emergency landslide warnings for Niijima Village, Oshima Town, and Toshima Village, which are part of the Izu Islands south of Tokyo. Level 5 is the highest on the JMA’s five-point warning scale. The agency also issued a Level 4 landslide alert for parts of Chiba and Saitama prefectures, which are near Tokyo. Footage from a live camera showed a river in Yakushima, Kagoshima Prefecture, swollen by heavy rainfall over the weekend. In response to the ongoing weather emergency, the Japanese central government has established a liaison headquarters at the prime minister's office to assess potential damage and coordinate emergency response efforts. The JMA warned that further heavy rain could affect wide areas along Japan’s Pacific coast as warm, moist air moves toward a rain front stretching across Honshu, Japan’s main island. The weather agency also warned that prolonged and localized torrential downpours, capable of causing significant damage, could develop in the northeastern Tohoku region as a seasonal rain front moves northward over the coming days. These forecasts highlight the ongoing challenges posed by the severe weather, which has already caused loss of life and disruption across the region.
