JR East to Resume E8 Shinkansen Train Operations
News from Japan Society Guide to Japan Jul 22, 2025 21:13 (JST) Tokyo, July 22 (Jiji Press)--East Japan Railway Co., or JR East, said Tuesday that it will gradually resume individual operations of E8 series Shinkansen trains on the Yamagata Shinkansen bullet train line from Aug. 1, as the cause of the malfunctions affecting them has been identified. JR East found that a higher-than-expected current flowed due to an improper combination of parts in the system that supplies power to the trains' electrical devices. In addition to the high current, the heat also affected the parts that shut off the current, causing them to malfunction. The trouble occurred on June 17, when an out-of-service E8 train became unable to accelerate while running between Utsunomiya and Nasushiobara stations in Tochigi Prefecture. As a result, Tohoku Shinkansen bullet train services between Tokyo Station and Sendai Station in Miyagi Prefecture were suspended for about five and a half hours. As other E8 trains also malfunctioned on the same day, JR East suspended individual operations of the E8 series, while partly halting Yamagata Shinkansen services.

JR East to suspend E8 shinkansen trains for time being
East Japan Railway, or JR East, said Wednesday that it will suspend some services on the Yamagata Shinkansen train line, following malfunctions found on E8 series Shinkansen trains. The railway operator said that it will halt individual operations of E8 trains until the cause of the trouble is identified. On Tuesday, an out-of-service E8 train became unable to accelerate while traveling northward between Utsunomiya and Nasushiobara stations in Tochigi Prefecture, leading to a service suspension between Tokyo Station and Sendai Station in Miyagi Prefecture for about five and a half hours. JR East said that a power supply device malfunctioned, causing the motor to stop working. The company added that three more E8 trains — two in service and one out of service — suffered issues during the service suspension. The E8 series entered service last March. Nine trains are in operation, while two are undergoing test runs. The four trains that malfunctioned were the latest version, delivered in November last year and after.
