The Tohoku, Joetsu and Hokuriku Shinkansen Lines resumed operations in the morning on Jan. 24 between Tokyo and Sendai, as well as between Tokyo and Takasaki, following widespread suspensions the previous day.

The first train of the day bound for Morioka, Yamabiko 51, left Tokyo Station at 6:04 a.m. on schedule, followed four minutes later by Toki 301, departing for Niigata.

A power outage in the morning on Jan. 23 halted three bullet train lines in eastern Japan in the affected sections for the entire day, forcing the cancellation of 283 trains and inconveniencing about 120,500 passengers.

The source of the power outage appears to be a train entering a section of the tracks where overhead wires were sagging for an unknown reason, causing an abnormal current flow that automatically halted the transmission of electricity, according to East Japan Railway Co. (JR East).
