Torrential rain over the weekend has left at least 485 houses flooded in Akita Prefecture, northeastern Japan, with more than 20,000 local residents still under evacuation orders, the prefectural government said Monday.

No injury or death has been reported so far, the local government said. Part of the Akita Shinkansen bullet train service was suspended Monday following track damage caused by the disaster, according to the operator East Japan Railway Co.

The Japan Meteorological Agency predicted intermittent heavy rain and thunder in the Tohoku region in northeastern Japan and Hokuriku area on the Sea of Japan coast through Tuesday due to a stalled rain front.

From Saturday to Sunday, over 300 millimeters of rain had been observed at multiple locations including Akita and Yokote cities.

In Daisen, one of the hardest-hit areas, an evacuation order for about 21,000 people of some 8,200 households has not been lifted. Akita Gov. Norihisa Satake said he is planning to ask for increased state financial support for recovery from the disaster.

Flooded rivers triggered a series of mudslides and a number of houses were stranded due to severed road access.

Two nursery schools in Akita and Daisen cities were closed Monday because of flooding, and water supply was cut off in five cities including Yurihonjo and Yokote due to damage to pipes.

Meanwhile, the governor Satake apologized Monday as he was out of the prefecture for golfing and missed an emergency meeting the previous day to share the extent of damage from the disaster.

"It was my mistake that I went out," the governor said. After playing golf with his friends in neighboring Miyagi Prefecture, he drank Saturday evening and although he learned about heavy rain in Akita, he could not drive back under the influence of alcohol, Satake said.

The governor said he headed to Akita on Sunday morning, but could not make it to the meeting as he got caught in heavy traffic.
