Nagoya’s worst hour of rain on record floods streets and stops trains

Note

Nagoya’s rain gauge did not whisper. On the afternoon of 8 September 2026 it printed 104.5 mm in sixty minutes — the highest hourly total in a record book that starts in 1890 — with 213 mm already on the 12-hour tape by 18:00 local. A linear rain band sat over western Aichi and into Gifu while water rose on the Kanare, Yada, Ueda and the wider Shonai system.

City hall went to Level 5 Emergency Safety Measures for river-adjacent wards covering more than 1.17 million people, telling residents in danger zones to get to a higher floor or a safer building now. At 18:20 local, JMA and the transport ministry matched that temperature with a Level 5 flood special warning for the Shonai River system. Tracks flooded. Bullet trains stopped. Four people were hurt across the prefecture. By late evening the Level 5 municipal orders were stepped back as gauges fell — the kind of quiet downgrade that still leaves overnight water, closed schools, and a Chuo Line out of service into the next morning.
