From Japan Today; April 28, 2019
Bullet train services between Tokyo and Niigata resumed Sunday, the second day of Japan’s extended 10-day holiday period, after a power outage suspended operation of the Joetsu shinkansen line for three and a half hours.
The outage, which occurred at around 7:20 a.m., caused delays of up to four hours to bullet train services, affecting about 42,600 people during the Golden Week holiday, which is longer than usual this year to celebrate the imperial succession.
