JR East announced that it will stop driving the Yamagata Shinkansen between Yamagata Station and Shinjo Station on the 7th and 8th due to heavy snowfall from the 7th.
As for conventional lines such as the Sea of Japan side of the Tohoku region and the Hokuriku region, there are routes that will not be operated from the 7th, so JR companies are calling for checking the latest operation status on their websites.
