Heavy rain lashed northeastern Japan's Fukushima and Niigata prefectures on Tuesday, prompting evacuation orders in affected areas amid fears of river flooding, while part of Tokyo observed hail in the afternoon, disrupting traffic.
Strong hail smashed sections of the platform's roof at JR Komagome Station on the Yamanote loop line in the capital, but no one was hurt, East Japan Railway Co. said.
Near JR Ikebukuro Station, hail covered the ground, the train operator said, adding temporary traffic disruption affected some 17,000 people.
The town of Tadami in western Fukushima ordered over 4,300 residents to evacuate, warning against river flooding and landslides. Local train service has been partially suspended, according to East Japan Railway.
In the city of Gosen and the town of Aga in Niigata, over 1,400 residents were ordered to move to shelters amid flood concerns, according to the municipalities.
There were no reports of injuries in the towns and city on Tuesday morning.
Elsewhere in Niigata, such as the cities of Nagaoka and Sanjo, an evacuation advisory was in effect on Tuesday, affecting over 20,000 people.
