Officially, the Kan-Etsu consists of two routes. Both begin in Tokyo and end in Niigata Prefecture. The Kan-Etsu Expressway Niigata Route consists of the entire Kan-Etsu Expressway from Nerima to Nagaoka, as well as the Hokuriku Expressway beyond Nagaoka to its terminus in the city of Niigata. The Kan-Etsu Expressway Jōetsu Route is concurrent with the Niigata Route until Fujioka Junction, where it branches off as the Jōshin-etsu Expressway and traverses Nagano Prefecture to its terminus in Jōetsu, Niigata.
