Typhoon No. 25 approaching Japan

Overview

Typhoon No. 25 is projected to impact Japan during the Silver Week holiday period. Initial reports indicated the storm would develop near the Mariana Islands and move toward the Ogasawara Islands around September 18, potentially reaching areas south of Kanto by September 21. Prior to the typhoon’s approach, regions like Kanto-Koshin had already experienced prolonged heavy rain and low sunshine, causing agricultural damage such as rice sprouting prematurely and vegetable price increases.

As the storm progressed, the Japan Meteorological Agency reported the typhoon moving north near Minamitorishima. Forecasts suggest the peak impact will hit the Kanto region around the morning of September 21, with warnings issued for heavy rain, strong winds, and high waves. There is a significant possibility that the typhoon could make landfall on the Boso Peninsula in Chiba Prefecture on September 21. In the Kanto region, rainfall could reach record levels, potentially exceeding a month’s worth of average precipitation in a single day.

Local authorities have warned of landslides, flooding, and storm surges, particularly in Chiba. Preparations and cancellations are already underway; for instance, a fireworks display at Tokyo German Village has been canceled, and the Rock in Japan Festival is monitoring the situation. Transportation is expected to face major disruptions. JR East has warned of potential delays, route changes, or cancellations for several lines in the Tokyo metropolitan area, including the Shonan-Shinjuku and Utsunomiya lines. In Hachijojima, all flights to Haneda and several ferry services have been canceled, resulting in local food shortages and a surge in hotel cancellations.
