The Japan Meteorological Agency reported a historic 104.5 mm of rain in a single hour, marking the highest hourly total recorded since 1890. This extreme weather triggered a level 5 emergency alert for the Shonai River and several districts. The flooding resulted in significant casualties and property damage, including at least one death from a landslide in Kawanehoncho and dozens of injuries. In Nagoya, the Ueda River overflowed its banks, and water was reported erupting from city manholes. Approximately 3,500 people sought refuge in emergency shelters, and about 400 Asian Games athletes and staff were moved to higher ground. Flooding inundated homes, damaged roads, and left hundreds of vehicles stranded. Transportation infrastructure faced severe paralysis, with major transit lines including JR, Meitetsu, and subway services experiencing suspensions. This led to massive accumulations of stranded commuters around Nagoya Station and the Sakae area. While major 2026 Asian Games venues reported no significant damage, the Japan Meteorological Agency warned that additional heavy rain could continue in the region. ## Timeline ### 2026-09-10: Nagoya hit by record rainfall causing floods and landslides Record rainfall in Nagoya and the Tokai region caused severe flooding, landslides, and at least one death.
