The latest update
Typhoon Dujuan is approaching eastern Japan after heavy rain hit the Izu Islands and parts of the Pacific coast. Reuters reported more than 300 mm of rain in some places since Saturday and the highest-level landslide emergency warning for Oshima in the Izu Islands.
Why it matters
The Japan Meteorological Agency warned rain could intensify near Kanto, including Tokyo and surrounding prefectures. The primary threat is not only wind: saturated slopes, swollen rivers and sudden concentrated downpours can become dangerous quickly. An Asian Games equestrian event was postponed, while official travel was also delayed.
What happens next
Authorities highlighted the risk of linear rain bands, which can dump exceptional rainfall over a narrow area for hours. Travellers should check transport operators and official local alerts, allow time for changes and avoid exposed coasts, riverbanks and mountain roads when warnings are active.

A practical safety checklist
Keep a charged phone, a backup battery, water and essential medicines available if alerts are issued. Download official weather and local emergency information before connectivity becomes difficult. Do not drive through flooded roads or assume a familiar river path is safe after heavy rain. If a local authority recommends evacuation, follow the designated route early rather than waiting for visible flooding. Weather reporting can explain the broad situation, but the instructions of local officials are the right source for immediate decisions.
For families and visitors, preparation is most useful before an alert becomes urgent. Know the nearest safe indoor location, keep tickets and documents accessible, and share a simple contact plan. Do not use this article as a substitute for a live emergency warning or an evacuation instruction.
