Hokutosei or the North Star night train, once plied its way nightly from Ueno Station in Tokyo to Sapporo. The train took approximately 16 hours in either direction Ueno-Sapporo. Blue Trains in Japan are long-distance sleeper trains, nicknamed for the color of the train cars. They consist of sleeper cars, and currently run on nine routes connecting major destinations within Japan across long distances, other routes being served by a fleet of newer limited-express sleeper trains which are not blue. Sadly, these blue trains have been disappearing one by one in recent years.
