The Tanigawa (たにがわ) is a high-speed train service operated by the East Japan Railway Company (JR East) on the Joetsu Shinkansen in Japan.
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.
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.
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.
