One dead as heavy rain lashes Japan; weather agency warns of landslides, rainbands

Heavy rainfall affected eastern Japan on Monday, leading to one fatality and multiple incidents of flooding and landslides. The Japan Meteorological Agency issued special warnings for Niijima Island due to record-breaking rainfall exceeding 480 millimeters in 24 hours. In Iwaki, Fukushima Prefecture, a woman in her 60s died after her car was submerged in an underpass. Additional injuries were reported in Chiba Prefecture. The agency also warned of potential prolonged rainbands in the Tohoku region. The central government activated a liaison headquarters to coordinate disaster response efforts. Further rainfall is expected across Pacific-facing regions as warm, moist air interacts with the ongoing rain front.

Heavy rain lashed Tokyo and surrounding prefectures on Monday, prompting warnings of landslides, rising river levels and flooding. The Japan Meteorological Agency urged residents to remain vigilant, citing the risk of severe weather conditions. A woman in her 60s was pronounced dead after her car became submerged in floodwaters near an underpass in Iwaki, Fukushima Prefecture, according to the local fire department. The heavy rainfall exceeded 480 millimeters in 24 hours on Niijima Island, triggering a special landslide warning. This amount of rain represents the highest recorded since local records began. The weather agency also issued a level 4 landslide alert for parts of Chiba and Saitama prefectures, which border Tokyo. Train services were disrupted, and some schools had to close due to the adverse weather. In the Tohoku region, the agency warned that rainbands could bring prolonged torrential downpours as a seasonal rain front moves north. Two individuals sustained minor injuries after falling during the heavy rain in Chiba, according to the prefectural government. The central government established a liaison headquarters at the prime minister’s office to evaluate potential damage and coordinate emergency responses. The weather service further cautioned that more rainfall is expected in areas facing the Pacific as warm, moist air approaches the rain front along Honshu. Footage showed a river in Yakushima, Kagoshima Prefecture, swollen by the heavy rains. The situation continues to evolve, with ongoing monitoring and response efforts underway.
