The experiential tunnel at the Seikan Tunnel Memorial Museum is a rare spot where you can walk and observe the underwater tunnel. To get to the Ryofu Sea Bottom Station, you need to ride the underground cable car "Mogura-gou". During the approximately 7-minute journey, you can experience the sensation of descending to a depth of 100 meters below sea level. Equipment and tools used at the construction site are on display, allowing you to learn about the history and technology of the Seikan Tunnel. It's also barrier-free, making it accessible for anyone to visit.
