TOKYO, Japan – Typhoon Dujuan moved away from Japan on Tuesday, leaving parts of the Tokyo region flooded and homes collapsed as rescuers searched for missing residents.

The supplied news update reported six people dead and six missing. A separately checked Reuters dispatch, citing Japan’s public broadcaster NHK, reported four deaths and six missing. The difference could not be reconciled immediately. Reuters also reported that about 45,000 households had lost electricity, citing Tokyo Electric Power.

The Storm Retreats, but the Danger Remains

According to the supplied report, residential streets in Sakura, Chiba Prefecture, were flooded, while multiple landslides struck Yokosuka in neighboring Kanagawa. In Miura, a woman in her 20s was unaccounted for after a mudslide hit an apartment building; another woman was reported missing nearby.

Japan’s immediate response has centered on rescue operations and warnings against treating improving weather as an all-clear. International reporting by Germany’s dpa also highlighted the continuing threat from saturated ground, alongside damage to homes and interruptions to road, rail and air transport.

Before the storm’s passage, the Japan Meteorological Agency warned that concentrated bands of rainfall could rapidly increase flood and landslide risks. An emergency landslide warning was issued for Oshima in the Izu Islands, illustrating how a storm tracking offshore can still threaten communities on land.

A Growing Challenge for Disaster Preparedness

Dujuan’s destruction comes against a documented increase in extreme rainfall in Japan. The meteorological agency’s Climate Change in Japan 2025 assessment found that hourly rainfall events of at least 80 millimeters occurred about 1.7 times as frequently in 2015–2024 as in 1976–1985. Annual rainfall totals, however, showed no clear long-term trend—a distinction that matters for drainage systems and emergency planning.

Those findings provide context, rather than an attribution of this particular storm to climate change. The broader policy question raised by Dujuan is whether evacuation arrangements, hillside protection and urban drainage can keep pace with increasingly concentrated rainfall.

For affected communities, that debate follows a more urgent task: finding the missing and determining when damaged neighborhoods are safe to re-enter.
