Foreign residents in the Kanto region should prepare for significant transportation disruptions and potential safety hazards as Typhoon No. 25 approaches, with the storm expected to make its closest approach on the afternoon of September 21, 2026. According to NHK, the large and powerful typhoon has already brought heavy rainfall to the Izu Islands and Kanto region even before its closest approach. The Choshi Meteorological Observatory issued Level 4 landslide disaster warnings for seven municipalities in Chiba Prefecture as of 6:50 AM on September 21, including Yachiyo, Funabashi, Shiroi, Noda, Nagareyama, Kamagaya, and Matsudo cities. Level 4 warnings represent the second-highest alert level in Japan's disaster warning system, indicating that residents in affected areas should evacuate immediately. The storm has already caused tangible damage across the region. In Sakura City, Chiba Prefecture, a landslide occurred around 1:30 AM on September 21, with soil collapsing near a residential home and breaking windows, according to police and fire department reports. In Chuo Ward, Chiba City, manhole covers were seen violently ejecting water around 2:00 AM, with witnesses reporting similar incidents at multiple locations in the area. Meteorologists warn that conditions will deteriorate further as the typhoon approaches. NHK's meteorologist Minami Toshiyuki explained that both rain and wind will intensify significantly during the afternoon and evening of September 21. There is particular concern about the potential formation of linear precipitation bands across Kanto-Koshin and Shizuoka Prefecture, which could lead to extreme rainfall in localized areas. Transportation networks across the region are experiencing major disruptions. According to NHK's transportation impact summary, JR East has announced that some train lines will suspend operations from the first trains of the day on September 21. The Tokyo Bay Ferry, which connects Kurihama Port in Yokosuka, Kanagawa Prefecture, with Kanaya Port in Futtsu, Chiba Prefecture, implemented planned service suspensions starting with the 3:25 PM departure from Kurihama and the 4:30 PM departure from Kanaya on September 20, canceling a total of nine ferry runs. Expats should expect additional cancellations and delays affecting rail services, flights, highways, and other ferry routes as the storm progresses. Those with travel plans should check with transportation providers frequently for updates and consider postponing non-essential travel. For foreign residents unfamiliar with Japan's disaster warning system, it's crucial to understand that Level 4 warnings require immediate action. If you live in one of the affected municipalities, you should evacuate to designated shelters or move to higher floors in sturdy buildings if evacuation is not possible. Local governments typically provide evacuation information through loudspeaker announcements, emergency alert apps, and television broadcasts. Residents should also prepare emergency supplies including drinking water, non-perishable food, flashlights, batteries, and important documents in waterproof containers. Secure outdoor items that could become projectiles in strong winds, and stay away from rivers, coastal areas, and slopes prone to landslides. The Japan Meteorological Agency advises residents to monitor weather updates closely through official sources such as NHK, local government websites, and the JMA website, which offers information in multiple languages. With the typhoon's closest approach expected during the afternoon and evening hours, conditions are likely to remain dangerous well into the night of September 21. Foreign residents should prioritize safety over work or other commitments and follow all official evacuation orders promptly. Japan's disaster preparedness infrastructure is robust, but individual vigilance and timely response to warnings remain essential for staying safe during severe weather events.
