The train was running in a coupled configuration, but for some reason it was separated. According to the local fire department, no injuries were reported. The train did not derail and JR is investigating the details. Due to this, operations have been suspended on both the upper and lower lines between Tokyo and Shin-Aomori Station, and as of 11:00 am there was no prospect of resumption of operations.Is this the first ever technical incident in the history of shinkansen operation?
