Typhoon No. 25 to Bring Heavy Rain and Strong Wind to Eastern Japan
A large and strong typhoon is approaching Japan, with forecasters warning of dangerous wind and rainfall in the coming days.
Typhoon No. 25, named Dujuan, is expected to make its closest approach to the Kanto region — the eastern area that includes Tokyo — on 21 October.
According to the latest updates, the storm has strengthened and is now categorized as "strong," with forecasts predicting a maximum instantaneous wind speed of around 50 meters per second.
Particularly violent gusts are expected near the Izu Islands as the typhoon moves through the region.
Heavy rainfall is also a major concern, with meteorologists warning that totals in Kanto could reach around 400 millimeters, a level comparable to the severe heavy rain disaster that previously struck Chiba Prefecture.
Rain is forecast to begin falling even before the typhoon makes its closest approach, meaning conditions could deteriorate well ahead of the storm's peak.
Officials say eastern Japan and the Tohoku region should remain on alert for heavy rain and strong winds until approximately 22 October.
As is typical with tropical storms, the exact trajectory and rainfall simulation figures are subject to change, and the latest forecast was updated as of 10 p.m. on 19 October.
Authorities are urging residents in vulnerable areas, particularly those near rivers or in low-lying regions, to prepare for potential flooding and to monitor updated forecasts closely.
Strong winds of this magnitude also pose risks to infrastructure, including the possibility of downed trees, damaged structures, and power outages.
This typhoon follows a pattern of severe seasonal storms that have previously caused significant damage in the Kanto and Tohoku regions, and authorities are treating the current threat with particular seriousness given the comparison being drawn to past disasters.
Residents have been advised to stay updated through official channels as the storm's path continues to be tracked and refined in the coming hours.
