A powerful typhoon that washed three American airmen in Okinawa out to sea, killing at least one, slammed central Japan on Monday, stalling trains and flights and triggering mudslides, before swerving to the Pacific Ocean.

Elsewhere in the Pacific, a separate typhoon whipped the Mariana Islands, including Guam, with high winds and heavy rain.

In Japan, bullet train service was suspended between Tokyo and Osaka because of the heavy rainfall, and more than 600 flights were canceled at Tokyo’s Haneda Airport. The trains resumed service later in the day, although with delays.

Typhoon Phanfone came ashore near the city of Hamamatsu shortly after 8 a.m., and traveled northward before turning eastward into the Pacific north of Tokyo.

Authorities advised more than 2 million people to evacuate, according to Kyodo News service.

One of the three U.S. airmen who went missing on Okinawa’s northern coast was found dead. The other two were still missing, according to the Air Force and the Japanese coast guard.

The Air Force said the search for the missing airmen had been interrupted by rough seas. Their names were being withheld pending notification of relatives. Okinawa is home to about half of the roughly 50,000 American troops stationed in Japan.

Japanese broadcaster NHK reported one death, with five people missing. NHK footage showed flooded areas of Kanagawa prefecture, southwest of Tokyo, where people were wading in knee-high muddy water, and buildings and parked cars were sitting in big pools of water.
