Typhoon unleashes heavy rain on islands south of Tokyo; evacuation and disaster warnings issued
A powerful typhoon brought torrential rains to the Izu island chain just south of Tokyo, prompting evacuation orders, flood and landslide alerts, and at least one death as conditions worsened across the region.
The Izu islands, about 280 km south of Tokyo, recorded record‐breaking rainfall as the storm struck.Authorities warned residents to remain vigilant for landslides and flooding in the affected zones and set up emergency shelters.
Hundreds of people evacuated from vulnerable areas to safe locations.
On Japan’s main island (Honshu), a man fishing in Oiso, Kanagawa Prefecture, perished after being swept away by waves.
The government continues to monitor weather conditions closely and urge residents to heed local advisories.
Rainfall was especially intense in the Izu island chain, where the storm’s moisture converged with local topography to intensify precipitation.
The Japanese authorities have a system of issuing layered warnings (for flooding, landslides, etc.) during such typhoons, and they mobilized evacuation protocols in multiple districts.
Coastal and low‐lying zones are particularly susceptible to storm surge, wave action, and runoff, compounding risks during typhoons.
Rain is expected to continue in some regions as the storm lingers or moves, increasing the threat of secondary landslides and flood surges.
Local governments are likely to maintain evacuation and alert status, and may expand the area under threat if precipitation escalates.
