Typhoon Chan-hom struck the Kanto region of Japan on Tuesday night, August 11, 2026, bringing with it severe weather conditions and the threat of flooding. This storm is particularly notable as it made landfall in Ibaraki Prefecture, the first occurrence since Japan began keeping records in 1951.
Weather Warnings and Impact
The Japan Meteorological Agency issued warnings for low-lying areas, citing the risk of rising river levels and potential overflows. Residents have been advised to prepare for heavy rain, with forecasts predicting up to 180 millimeters in Kanto-Koshin.
Warm, moist air flowing into the typhoon will create unstable atmospheric conditions, leading to heavy rainfall across a wide region from northeastern to western Japan.

As of early Wednesday morning, Chan-hom was located over Ogaki in Gifu Prefecture, moving westward at approximately 40 kilometers per hour. The storm's center had an atmospheric pressure of 996 hectopascals and maximum gusts reaching 90 kilometers per hour.
