Typhoon Dujuan Hit Japan: What Travelers and Residents Should Check Now

Verified Baseline

Deaths, landslides and widespread outages are confirmed

Typhoon Dujuan—identified by Japan’s weather service as Typhoon No. 25—brought exceptional rain to the Tokyo region and other parts of eastern Japan. Reuters, citing NHK and authorities, reported at least four deaths, six missing people and tens of thousands of households without power as rescue work continued in Chiba and Kanagawa.

The Japan Meteorological Agency’s typhoon service tracked the large storm along the Pacific coast. East Nippon Expressway said in a September 22 road notice that inspections, cleanup and repairs were continuing on affected highways.

What Changed

The immediate threat is shifting from active rainfall to damaged terrain and infrastructure

Clearing weather does not reset risk to zero. Water can keep moving through slopes after rain ends, rivers can remain high, and hidden road damage can emerge during inspections. That distinction matters because a sunny forecast may encourage travel before local evacuation orders, rail service and road restrictions have been lifted.

The most useful question is therefore not simply “Has the typhoon passed?” but “Have the specific route, neighborhood and utility serving my destination been cleared?” Conditions can differ sharply between central Tokyo, coastal Kanagawa, Chiba’s river basins and rural slope communities.

Practical Checks

Verify the exact route and destination before moving

• Residents: follow municipal evacuation information and JMA landslide and flood alerts; do not enter a damaged building or approach a swollen river solely because rain has stopped.
• Travelers: confirm the operating status of both the flight or train and the ground connection to the airport, hotel or station.
• Drivers: use official expressway and local road notices; never cross standing or moving water when depth or pavement condition is unknown.
• Households without power: use generators only outdoors and away from openings because carbon monoxide is odorless and can be fatal.

Safety note: This is general information, not a substitute for instructions from Japanese emergency authorities. If an official evacuation order applies to your location, follow it.

What Remains Uncertain

The toll and restoration timeline may change

Search operations were still underway when this article was published, so casualty figures can rise or be revised. Power restoration depends on access to damaged lines, while transport reopening depends on inspections rather than a single nationwide timetable.

It is also too early to quantify total economic damage or attribute Dujuan’s specific intensity to climate change. Warmer air can hold more moisture, but determining how much climate change influenced an individual storm requires formal attribution work.
