The Derailment of Jōetsu Shinkansen (上越新幹線脱線事故), occurred when a bullet train derailed on October 23, 2004 during an earthquake in the Chūetsu region of Niigata Prefecture, Japan. It is the first derailment of a commercially operated Shinkansen (high speed rail in Japan).

The train, which was heading for Niigata Prefecture from Tokyo with train number "Toki 325 (とき325号)", had 8 of 10 cars (except cars 6 and 7) derailed due to the earthquake.
