Overview
- Dujuan moved over eastern Japan on Monday, triggering municipal evacuation orders that covered about 1.9 million people across six prefectures including Tokyo, Chiba and Kanagawa.
- Official tallies remain provisional and vary by source, with reports from disaster agencies and news outlets citing between four and seven deaths, multiple people missing and dozens injured as search-and-rescue operations continue.
- The storm shut hundreds of flights at Haneda and Narita and prompted widespread rail suspensions, with major carriers and Tokyo-area operators canceling roughly 275–500 flights and pausing many train lines.
- The Japan Meteorological Agency recorded locally extreme totals such as 832 millimeters of rain in 48 hours on Oshima and a 24-hour record of 282.5 millimeters in Tokyo’s Edogawa ward, which drove landslides, flooding and building damage.
- Tens of thousands of homes lost power, emergency agencies issued high-level landslide warnings in vulnerable areas, and authorities warned that recovery and damage assessments will take days as crews restore services and check at-risk slopes.
