Tokyo issues Level 4 flood alert for Zenpukuji River as Typhoon 6 intensifies
Authorities have confirmed evacuation protocols for residents in high-risk zones as simultaneous landslide and flood warnings impact multiple prefectures across Japan.
The Japan Meteorological Agency and the Tokyo Metropolitan Government issued a Level 4 flood hazard alert for the Zenpukuji River in Tokyo at 7:10 am on June 3, 2026. The designation indicates that flooding is likely, prompting officials to warn residents to take immediate protective action.
Local municipalities have confirmed evacuation information regarding individuals in dangerous locations, with authorities actively verifying the status of those at risk. The alert was issued in direct response to the ongoing impact of Typhoon 6, which has brought heavy rainfall to the capital region.
This warning coincides with a broader pattern of severe weather across Japan. Simultaneous Level 4 landslide hazard alerts have been issued for Yokosuka City in Kanagawa Prefecture, as well as for the cities of Ito, Atami, and Shimoda in Shizuoka Prefecture.
In Shizuoka, a line-shaped precipitation band has developed in the Izu region, significantly increasing the risk of disaster. This weather system follows earlier predictions issued on June 2 for parts of Kochi, northern Tokushima, Wakayama, and Mie, where the band has already caused power outages affecting approximately 17,000 households in Shikoku.
Further south, the Japan Meteorological Agency issued a Level 5 flood special warning for the Kozagawa River in Wakayama Prefecture. The escalation of warnings across multiple regions underscores the widespread nature of the typhoon’s impact and the coordinated response required from local and national authorities.
