Due to a power outage caused by a fire at a substation, the JR Utsunomiya Line and Takasaki Line, which had been suspended from operation before 1:00 pm on the 10th, resumed operation around 8:30 pm.
At one point, up to 10 JR lines operating in the Tokyo metropolitan area were suspended, but all lines except the Shonan-Shinjuku line, which was suspended all day due to the disruption of the timetable, have now resumed operation.
