Foreign residents in Japan's Kanto region should prepare for significant weather disruptions as Typhoon No. 25 approaches the Tokyo metropolitan area, with closest approach expected on the evening of September 21st, according to reports from NHK and other Japanese media outlets. The large-scale typhoon is currently moving through waters west-southwest of the Ogasawara Islands and is forecast to maintain strong intensity as it tracks northward toward the Japanese mainland. According to NHK, the storm is expected to impact the Izu Islands and Kanto region from September 20th onward, bringing heavy rainfall and strong winds to areas from Tokai through Tohoku along the Pacific coast. Yahoo Japan reports that the typhoon's closest approach to the Kanto region is anticipated on the evening of September 21st, meaning residents should expect the most severe conditions during Sunday evening and night. This timing presents particular challenges for weekend travel plans and outdoor activities. The Ogasawara Islands are already experiencing high waves and dangerous sea conditions, with authorities issuing warnings for residents and maritime traffic in the area. As the typhoon moves closer to the main islands, similar conditions are expected to develop across a much wider area, including popular coastal destinations and transportation hubs. For foreign residents, understanding Japan's typhoon protocols is essential. Transportation disruptions are highly likely, with potential suspensions or delays affecting trains, buses, and flights. Major railway operators including JR East typically make decisions about service suspensions several hours in advance, but travelers should monitor official announcements closely. Domestic and international flights at Narita and Haneda airports may face cancellations or significant delays. Expats living in apartments should take preventative measures now, before conditions deteriorate. Secure any balcony items that could become projectiles in strong winds, including laundry poles, plants, and outdoor furniture. Check that windows close properly and consider applying tape in a cross pattern to prevent glass scattering if breakage occurs. Stock up on essential supplies including water, non-perishable food, flashlights, batteries, and any necessary medications. Those unfamiliar with Japanese emergency broadcasts should download the NHK World app or other English-language emergency alert services. Local governments also distribute information through loudspeaker systems, though these announcements are typically in Japanese only. The Japan Meteorological Agency website offers English-language typhoon tracking and warning information. Heavy rainfall associated with the typhoon poses risks beyond just wind damage. Rivers may overflow, and low-lying areas could experience flooding. Residents living near rivers or in flood-prone zones should familiarize themselves with local evacuation routes and designated shelters. Many municipalities provide hazard maps showing flood risk areas, often available in simplified formats at ward offices. Businesses may adjust operating hours or close entirely during the storm's peak intensity. Convenience stores typically remain open but may experience supply shortages. Restaurants and shops, particularly in entertainment districts, often close early when typhoons approach. The Pacific coastal regions from Tokai to Tohoku should prepare for extended periods of rainfall even before the typhoon's direct approach. This precipitation could begin as early as September 19th in some areas, with conditions gradually intensifying. Foreign residents should avoid unnecessary travel during the typhoon's closest approach and stay indoors during peak conditions. If evacuation orders are issued for your area, comply immediately. Understanding the Japanese evacuation level system is crucial: Level 3 means elderly and vulnerable people should evacuate, Level 4 means everyone should evacuate, and Level 5 indicates immediate life-threatening danger. Stay informed through official channels and exercise caution. Typhoons are serious weather events requiring appropriate preparation and response from all residents, regardless of previous experience with tropical storms in other countries.
