(The Weather Channel) – Two people died and at least 20 remained missing after a wave of black mud, water and debris slammed into houses southwest of Tokyo Saturday amid days of heavy rainfall.

Prime Minister Yoshihide Suga told reporters that 19 people had been rescued as more than 1,000 rescuers descended on the disaster area, according to the Associated Press. The incident occurred in the town of Atami, about 65 miles southwest of Tokyo. As many as 130 homes and other structures were damaged, Suga also said.

“Because of the heavy rain, the ground loosened and the mudslide occurred … it picked up speed and swept away houses together with people,” Shizuoka Gov. Heita Kawakatsu told reporters, according to the Japan Times.

Witnesses recounted the scene.

“I heard a horrible sound and saw a mudslide flowing downwards as rescue workers were urging people to evacuate. So I ran to higher ground,” a leader of a temple near the disaster told NHK.

“When I returned, houses and cars that were in front of the temple were gone.”

Video posted to social media showed the moment the wave came crashing down a hillside.

Some 35,000 people were ordered to evacuate, according to the AP. Evacuation orders were also issued in the cities of Yokohama, Chiba and Shizuoka, the Japan Times reported.

Atami is a popular hot-spring resort town in the prefecture of Shizuoka. The area has been hammered by heavy rainfall in recent days, with more than 19 inches of rain in the past 24 hours alone. That’s more rain than the region normally sees in the entire month.

The rain appears to have triggered several fast-moving landslides, including the one that crushed houses and carried away cars. [more]

Japan Landslide: 2 Killed, 20 Missing as Search for Survivors Continues in Atami


A powerful mudslide carrying a deluge of black water and debris crashed into a row of houses in a town west of Tokyo following heavy rains on 3 July 2021, leaving at least 19 people missing officials said. Dozens of homes may have been buried in Atami, a town known for hot springs, said Shizuoka prefecture spokesperson Takamichi Sugiyama. Public broadcaster NHK gave the number of missing people at 20, but Sugiyama said the prefecture confirmed at least 19, although he said the number may grow. Torrential rains slammed parts of Japan starting earlier in the week and experts said dirt had been loosened, raising the landslide risk in a country filled with valleys and mountains.
