The is a Japanese funicular railway (often referred to as a "cable car" in Japan) in Sotogahama, Aomori Prefecture, operated by the Seikan Tunnel Museum.
The narrow-gauge line descends from the Seikan Tunnel Memorial Hall, near Cape Tappi, into the underground Tappi-Kaitei Station on the Seikan Tunnel, which is one of the longest railway tunnels in the world (which opened in March 1988), second to the Gotthard Base Tunnel in Switzerland that opened in June 2016.
The funicular was originally installed to transport workers and goods during construction of the Seikan Tunnel but is now an attraction at the Seikan Tunnel Museum.
