Passengers on the Hayabusa number 46 bullet train ended up stuck in a tunnel for 15 minutes while checks were made.
Japanese media said the train travelled for about 4km (2.5 miles) with the door open as it slowed to a stop – but no-one was near the open door.
The national transport ministry asked the company to make sure the issue was not repeated, Japanese media said.
Japan's famous bullet trains, known as shinkansen, are high-speed rail systems much faster than conventional trains.
