Heavy rain east of Tokyo triggers flash flooding that kills at least four people and leaves one person missing. Floodwaters inundate roads and dozens of homes, prompting emergency responses and stranding residents and travelers.

The rainfall is described as record-breaking in some reports, with water levels rising quickly overnight. Outlets also report power outages and widespread disruption to transportation, including train service interruptions and problems for air travel. Some people are left unable to move through affected areas as authorities respond and assess damage.

While coverage is broadly aligned on the flooding’s impact and the reported death toll, individual outlets differ in emphasis. One report focuses more on travel disruptions and the scale of stranded people, while another highlights infrastructure effects such as electrical outages. All accounts describe severe, rapidly developing weather that overwhelms local systems and causes dangerous conditions for those near waterways.
