History

The name Tanigawa (written as "谷川") was first introduced on 15 November 1982 for limited express services operating between Ueno in Tokyo and Minakami on the Jōetsu Line.^[3]

From 1 October 1997, the name (written as "たにがわ") was used for the all-stations services between Tokyo and Echigo-Yuzawa on the Jōetsu Shinkansen, replacing the previous Toki all-stations services. During the winter skiing season, trains terminate and start at the seasonal Gala-Yuzawa Station.^[1]

E2 series 10-car sets were introduced on three return Tanigawa services daily from 26 January 2013, operating at a maximum speed of 240 km/h.^[2][4]
