Typhoon Dujuan approaches Kanto region, bringing severe transport disruptions and cancellations.

Forecasts indicate the typhoon could produce gusts of around 50 meters per second in exposed areas, with disruptions potentially beginning before the storm’s closest approach and continuing afterward for inspections and safety checks.
The projected track has the storm passing near Miyakejima on the afternoon of September 21 before moving offshore of the Boso Peninsula at night; Chiba could enter the typhoon’s violent-wind zone even without a direct landfall.
Several specific Chiba rail suspensions have been scheduled for September 21: the Kururi Line will stop all day, while portions of the Uchibo and Sotobo lines are due to halt from about 2 p.m.; the Togane Line, sections of the Sobu Main and Narita lines, and the Kashima Line are also scheduled for afternoon suspensions.
Travelers may face airport-access problems even when flights operate, because reduced rail service could disrupt last-mile connections to Haneda and Narita, create crowded stations and cause missed connections.
Izu Oshima had already received more than 700 millimeters of rain during an extreme-rainfall event earlier in September, and the short interval before Typhoon No. 25 has raised concerns that saturated or previously damaged areas could be especially vulnerable to further disasters.
Typhoon Dujuan is bearing down on Japan's Kanto region, expected to pass closest to the area from Monday afternoon through late September 21. Hindustan Times reported that the storm brings violent winds near 35 meters per second and heavy rain that could affect coastal areas like Chiba even without a direct hit. Airlines have already begun canceling flights, and rail networks are preparing for major disruptions across Tokyo and surrounding prefectures.
The typhoon's central pressure sits near 970 hectopascals, with gusts potentially reaching 50 meters per second in exposed areas, Jagran Josh noted. Heavy rain has already drenched the region—Izu Oshima received more than 700 millimeters earlier this month—raising fresh concerns about flooding in saturated areas just before the storm's arrival.
All Nippon Airways has canceled all flights to and from Hachijojima on September 20 and 21. Travel and Leisure Asia reported that Japan Airlines and ANA have cancelled hundreds of domestic and international flights across Tokyo. Approximately 500 flights were canceled in Tokyo alone, with more cancellations expected at Haneda and Narita airports as the typhoon approaches.
JR East has scheduled major service cuts across Chiba's rail lines for September 21. The Kururi Line will close entirely, while portions of the Uchibo and Sotobo lines are due to halt from around 2 p.m. The Togane, Kashima, and parts of the Sobu and Narita lines are also scheduled for afternoon suspensions. Disruptions could begin before the typhoon's closest approach and extend into September 22 for safety inspections.
The Guardian reported that the Izu Islands have been evacuated due to heavy rain and flooding risks. Izu Oshima received more than 700 millimeters of rain during an extreme-rainfall event earlier in September. The short interval before Typhoon Dujuan arrives has raised concerns that saturated and previously damaged areas could face additional disasters from the incoming storm.
Travelers may face major problems even on flights that do operate. Russia Tourism News noted that typhoon disruptions extend beyond flight cancellations—reduced rail service could block access to Haneda and Narita, creating crowded stations and missed connections. The combination of flight cancellations, rail suspensions, and airport-access problems could strand passengers for days as the storm passes through the Kanto region.
