History
Tairyō-kōdō Station is the underground terminus of the Seikan Tunnel Tappi Shakō Line, a 914 mm-gauge funicular run by the Seikan Tunnel Museum in Sotogahama, Higashi-Tsugaru District, Aomori Prefecture, connecting Seikan Tunnel Museum Station on the surface with Tairyō-kōdō Station deep inside the Seikan Tunnel's Tappi Tei-ten (former Tappi-Kaitei undersea station area). The line opened in 1988 with the Seikan Tunnel itself — the museum opened on 11 March 1988 and the tunnel was put into service on 13 March 1988 — and was built originally to move workers and materials during tunnel construction. Tairyō-kōdō Station has one staff member on duty, the 778 m total run is single track with no passing loop (a small worker-haulage branch exists near Tairyō-kōdō), and the train is the single-car "Seikan 1" / Mogura-gō with a 40-passenger capacity.

Notes
Tairyō-kōdō Station is effectively an attraction inside the Seikan Tunnel Museum rather than a transport hub — but it is licensed and regulated as a real railway under the Railway Business Act, so the line has to publish a fare table, a timetable and an annual safety report, and the operating data is also reported through Japan's national transport statistics.
