Seikan Tunnel Museum

At the Seikan Tunnel Memorial Museum, you can see panel displays and videos that explain the history of the world's longest undersea tunnel connecting Hokkaido and Aomori Prefecture, as well as the construction process. There is a tunnel you can experience, and you will take the cable car 'Mogura-go,' which is 778 meters long and takes 8 minutes. The experience of going to a tunnel 140 meters below sea level is precious.
