Exhibition Hall where visitors can learn the history of Seikan Tunnel.
It needed 65 years for Seikan Tunnel to complete after it was originally planned. The Exhibition Hall has several documents that introduce the history during these years and how this tunnel was actually built. The project proceeded even under severe conditions. Let’s follow the tracks of history under which this tunnel was constructed.
Go down to 140 meters below sea level on a cable car “Mogura”.
You can actually go through the shaft down to the tunnel and see how this 53.85 km long tunnel was constructed 240 m below the sea level. If you take the cable car called “Mogura (mole)” on Seikan Tunnel Tappi Shako Line, the shortest railroad in Japan, it leads you down along the inclined shaft leaning 14° to 140 m below the sea level in only 9 minutes.
Underground tunnel that shows the passion of the massive construction.
A part of the underground tunnel is used as a special exhibition area where visitors can look around in 45 minutes. They have machinery and devices that were actually used to excavate this tunnel. Walking around these exhibits makes us feel admiration for the technology and the passion of the workers who completed this massive construction that Japan boasts about to the world.
