The operator of the Hokuriku Shinkansen says it will operate nearly 90 percent of its bullet trains from Friday, when it resumes services on its entire route.
The Shinkansen line connects Tokyo and the city of Kanazawa in central Japan, via Nagano.
The line has been partially suspended since Typhoon Hagibis battered the region this month. Some of the trains were inundated when the typhoon flooded a depot in Nagano.
The operator, East Japan Railway Company, on Wednesday published a temporary timetable ahead of the resumption.
The firm says the number of trains will be reduced by 14 to 104, about 88 percent of its usual capacity, due to a shortage of cars.
The company says it will consider using trains it planned to use for another Shinkansen line on the Hokuriku line to resume usual service as soon as possible.
