Foreign residents across Japan's Kanto region should prepare for significant disruptions this holiday weekend as Typhoon No. 25 approaches with strong winds and heavy rainfall expected from September 21-22, 2026. According to NHK, the large and powerful typhoon is forecast to approach the Pacific coast of eastern Japan, including the Kanto region, while maintaining its strong intensity. The Japan Meteorological Agency warns that areas from Tokai through Tohoku along the Pacific coast could receive rainfall equivalent to an entire month's worth of September precipitation in just one day. This exceptional rainfall raises serious concerns about flooding, landslides, and other weather-related hazards. The timing of Typhoon No. 25 coincides with a three-day holiday weekend, compounding the impact on both transportation networks and planned events. Transportation authorities have already begun announcing service disruptions across multiple modes of travel. Airlines are cancelling flights, while railway operators are preparing for potential service suspensions, according to reports from Livedoor News. Foreign residents planning to travel during the holiday period should expect significant delays and cancellations affecting both domestic and international routes. The disruptions extend beyond transportation infrastructure. Yahoo Japan Business reports that numerous events scheduled for the holiday weekend are being cancelled due to the approaching typhoon. These cancellations affect outdoor festivals, concerts, sporting events, and other public gatherings across the affected regions. Expats who purchased tickets or made plans for weekend events should check official websites and social media channels for the latest cancellation announcements and refund information. For foreign residents unfamiliar with Japan's typhoon season, understanding the potential risks is crucial. The combination of heavy rainfall and strong winds can create dangerous conditions including flash flooding in urban areas, overflowing rivers, and falling debris from damaged structures. Low-lying areas and regions near rivers are particularly vulnerable. Residents in these areas should prepare evacuation plans and identify their nearest designated evacuation centers. Practical preparation steps include securing outdoor items that could become projectiles in strong winds, stocking emergency supplies including food, water, flashlights, and batteries, and ensuring mobile devices are fully charged. Foreign residents should also familiarize themselves with local emergency alert systems. Most smartphones in Japan receive automatic emergency alerts, but users should verify their settings are configured correctly. Language barriers can complicate emergency situations, so expats should download translation apps and save important emergency phrases in Japanese. The Japan Meteorological Agency website offers weather information in English, while NHK World provides English-language emergency broadcasts. Local ward offices typically provide multilingual disaster information through their websites and social media accounts. Transportation planning requires extra attention during this period. Those with essential travel needs should monitor railway and airline websites continuously, as service decisions may change rapidly based on weather conditions. Many transportation companies post updates on English-language Twitter accounts. Travelers should also consider purchasing travel insurance that covers weather-related cancellations. The typhoon's approach serves as a reminder for all foreign residents to review their disaster preparedness plans. This includes knowing evacuation routes, understanding local warning systems, and maintaining emergency supply kits. Japan's typhoon season typically runs from May through October, making such preparation an ongoing necessity rather than a one-time concern. As the holiday weekend approaches, foreign residents should prioritize safety over convenience. Avoiding unnecessary travel, staying informed through official channels, and following instructions from local authorities remain the best strategies for weathering Typhoon No. 25 safely. Those requiring assistance should contact their local ward office or embassy for guidance in their native language.
