    TL;DR

    Typhoon No. 25, known internationally as Dujuan, could make landfall near Tokyo on the Boso Peninsula on Monday, prompting warnings of floods and landslides. JR East says train services may be suspended from Sunday evening as Japan enters its five-day holiday period.

    Japan's weather agency on Saturday warned of landslides and flooding along the country's western and northern coasts over the next several days, as a typhoon threatened to make landfall near Tokyo early this week.

    Storm Track and Intensity

    The season's 25th typhoon, identified in international tracking reports as Tropical Storm Dujuan, was moving northwest at 15 kilometers per hour south of the main island of Honshu as of 6 p.m., according to the Japan Meteorological Agency (JMA). The storm registered an atmospheric pressure of 975 hectopascals at its center and packed maximum gusts of 162 kph.

    Dujuan formed near the Mariana Islands before tracking toward Japan, and forecasts indicate it could reach severe tropical storm strength, with winds of 25 to 33 meters per second, as it approaches the Kanto region.

    Landfall Risk Near Tokyo on Monday

    The typhoon could make landfall on the Boso Peninsula in Chiba Prefecture, east of Tokyo, on Monday, two days into Japan's five-day holiday period, known as Silver Week. The JMA said the storm is expected to bring heavy rain, strong winds and high waves, increasing the risks of flooding in low-lying areas.

    • Landslide and flooding warnings cover Japan's western and northern coasts over the coming days.
    • Heavy rain, strong winds and high waves are forecast as the system nears Honshu.
    • Low-lying areas face a heightened risk of flooding.

    Train Suspensions and Holiday Disruption

    JR East advised that train services in some areas of Chiba and other prefectures may be suspended from Sunday evening through Monday due to the typhoon. The timing also coincides with major holiday events, including the Tokyo Game Show, one of the world's largest video game exhibitions.

    Preparations and Public Advisories

    Municipalities across the Kanto region are inspecting drainage infrastructure and preparing evacuation centers for vulnerable populations living near steep slopes and major riverways, according to Japanese disaster management authorities.

    The JMA continues to issue real-time advisories, urging residents to secure loose outdoor items and avoid unnecessary travel during the storm's peak. People in areas along the storm's path are being encouraged to monitor the latest updates as the typhoon approaches during the holiday week.
