was a railway station on the Kaikyo Line in Sotogahama, Aomori, Japan, operated by Hokkaido Railway Company (JR Hokkaido). The station is located within the Seikan Tunnel below the seabed of the Tsugaru Strait linking the main Japanese island of Honshu with the northern island of Hokkaido. It was closed to passengers from November 10, 2013, to make way for the construction of the Hokkaido Shinkansen high-speed train line.[1] It is an emergency escape point.
Tappi-Kaitei Station was served by the Kaikyō Line, but only a few trains actually stopped at this station.
Tappi-Kaitei Station had two opposed side platforms serving two underground tracks. However, only the northbound platform was used. The platforms are connected by an underground cable car to the surface. The station housed a museum detailing the construction and operation of the tunnel. Yoshioka-Kaitei Station, Japan's deepest underground station, is located on the Hokkaido side of the tunnel.
Tappi-Kaitei Station opened on March 13, 1988. It was closed to passengers from November 10, 2013 due to construction work connected with the Hokkaido Shinkansen,[2] and formally closed as of the end of March 14, 2014.[3]
