TOKYO - Heavy rain across parts of Japan has killed one person and left three missing, the authorities said on Saturday, with thousands issued evacuation warnings and left without power.

The inundation has been caused by the remnants of former Typhoon Mawar, now downgraded to a tropical storm.

A rescue team in central Aichi region’s Toyohashi, where the country’s highest-level evacuation alert was issued on Friday, “found a man approximately in his 60s in a submerged car, but he was later confirmed dead”, a city official said.

In western Wakayama, where several rivers burst their banks, officials said that they had resumed the search for a man and a woman missing in the region.

Dozens of rescue workers also searched for a resident who could not be reached after his house was engulfed by a landslide in central Hamamatsu city.

A total of six people were seriously injured and 29 suffered minor injuries as at Saturday afternoon, the Fire and Disaster Management Agency said.

In central and western Japan, many evacuation orders – which are non-compulsory, even at the highest level – were downgraded on Saturday as rains eased.

Warnings issued in areas close to Tokyo early in the early morning due to flooding risks were later lifted.

With several cities including Aichi’s Toyohashi and Koshigaya near Tokyo reportedly seeing the highest 24-hour rainfall on record, the Japan Meteorological Agency urged residents to “be on high alert for landslides, overflowing rivers and flooding of low-lying areas”.

About 4,000 households in regions close to Tokyo suffered power outages early on Saturday, the Tokyo Electric Power Company said, but it was possible to mostly resolve the issue several hours later.

Shinkansen bullet trains were temporarily suspended between Tokyo and Nagoya, but Japan Railway said they resumed operations around noon.

On Friday, top government spokesman Hirokazu Matsuno warned of “extremely heavy rainfall with thunderstorms” in a wide area over the next three days.

Scientists say climate change is intensifying the risk of heavy rain in Japan and elsewhere, because a warmer atmosphere holds more water.

Strong rain in 2021 triggered a devastating landslide in the central resort town of Atami that killed 27 people.

And in 2018, floods and landslides killed more than 200 people in western Japan during the country’s annual rainy season.

Earlier this week, Mawar – then a typhoon – passed just north of the Pacific island of Guam, uprooting trees and leaving tens of thousands of homes temporarily without power. AFP
