When a massive storm rolls toward a mega-city like Tokyo, normal life doesn't slow down gradually. It stops.
Typhoon Dujuan slammed into Japan with devastating force, packing winds roaring up to 144 kilometres per hour and triggering evacuation advisories for more than 1.6 million residents. If you were planning a quiet Monday commute, you found yourself trapped in airports, wading through knee-deep water, or staring at emergency alerts on your phone. Two people lost their lives due to sudden landslides in Chiba and Kanagawa prefectures, turning a standard seasonal weather warning into a tragedy.
Storms of this magnitude expose how fragile modern transport networks can be when nature decides to test them. Let's look at what actually happened on the ground and why Typhoon Dujuan caught so many off guard.
The Scale of the Disruption Near Tokyo
Japan deals with typhoons every year. People expect heavy rain in late summer and early autumn. Even so, the sheer volume of water dumped by Dujuan shocked meteorologists.
The Japan Meteorological Agency warned that total rainfall could surpass the entire average monthly total for September in just a couple of days. That prediction came true. Major transportation hubs felt the immediate impact. Japan Airlines scrapped 135 flights, while All Nippon Airways grounded another 140. Thousands of travelers spent the day sleeping on the floor at Haneda Airport, waiting for updates that rarely brought good news.
- Evacuations: Over 1.6 million people urged to leave high-risk zones.
- Power outages: More than 9,000 households cut off from electricity.
- Event cancellations: The final day of the Tokyo Game Show closed early, alongside outdoor music festivals and scheduled baseball games.
Local mayors took to social media to warn drivers. In Kamakura, streets near the station transformed into rivers. Mayor Takashi Matsuo posted urgent warnings on X telling residents that driving had become far too dangerous.
Why Dujuan Hit So Hard
Typhoons pick up incredible energy as they move across warm ocean waters. Dujuan tracked dangerously close to Katsuura City, pushing a wall of high waves and torrential rain directly into the Kanto-Koshin region.
Landslides represent the deadliest threat during these events because the soil becomes completely saturated in minutes. In Sodegaura, Chiba Prefecture, a woman in her forties narrowly survived after driving straight into sudden road debris. Other areas weren't as fortunate, as mudslides crashed directly into homes, trapping residents before rescue teams could arrive.
Emergency services faced grueling conditions. Firefighters and police worked through blinding sheets of rain to clear blocked roads and check on vulnerable residents. Prime Minister Sanae Takaichi had to delay her departure to the United Nations General Assembly in New York by four hours, highlighting how high-level government schedules had to bend to the storm's will.
Handling Extreme Weather in Japan
If you live in Tokyo or find yourself visiting during typhoon season, preparation is your only defense. Japan's infrastructure is among the best in the world, yet nature still wins some rounds.
Check local hazard maps before booking hotels in coastal or low-lying areas. Keep an emergency go-bag ready with water, non-perishable food, and portable phone chargers. Pay attention to evacuation advisories immediately. They aren't legally mandatory, but waiting until water enters your home is a gamble you shouldn't take.
Dujuan has now shifted northeast, heading back out across the Pacific toward the Aleutian Islands. Clear skies are returning, but the cleanup will take weeks. Check your airline or railway app before heading out if you're traveling through the capital region today. Stay safe, and don't underestimate the water.
