TOKYO - Tohoku Shinkansen bullet train service resumed on Thursday after a partial suspension between JR Nasushiobara Station in Tochigi Prefecture and JR Morioka Station in Iwate Prefecture, due to a delay in maintenance work, JR East said.

The operator said that a maintenance vehicle malfunctioned during nighttime maintenance work, causing a disruption to service between JR Sendai and Koriyama stations before affecting a wider area.
