About Seikan Tunnel
The Seikan Tunnel is an undersea tunnel located in northern Japan and is the second longest railroad tunnel in the world (after the Sankoda Base Tunnel, which is scheduled to open in 2017). It crosses the Tsugaru Strait between the Japanese islands of Honshu and Hokkaido and runs through Aomori Prefecture on Honshu Island and Chikuchi Town in Ueno-gun, Hokkaido, and is 53.85 kilometers long, greatly reducing travel time between Honshu and Hokkaido.
Construction of the Seikan Tunnel began on September 28, 1971, and the tunnel was opened on March 10, 1985, and officially opened to traffic on March 13, 1988; the deepest part of the tunnel is 140 meters below the sea surface and 100 meters below the sea floor, making it difficult to build. The construction of the tunnel not only facilitated the connection between Honshu and Hokkaido, but also played an extremely important military role in ensuring smooth traffic between Honshu and Hokkaido when the Tsugaru Strait was locked and Hokkaido would become an isolated island, and military supplies could be transported to Hokkaido. In recent years, the Seikan Tunnel Memorial Hall and the Seikan Tunnel Entrance Plaza, which are associated with the Seikan Tunnel, have become more valuable for visitors.
How to get there
35 minutes on foot from Tsugaru Hamana Station
I found this place along the street on a drive before stopping at the Seikan Tunnel Memorial Museum.
I thought it was located near the Seikan Tunnel, but it was far away.
It just so happened that the Shinkansen was passing by at the right time, and there was a crowd of people gathered at the spot to take pictures.
We were happy to be able to set up our cameras and take pictures to commemorate the event.
There was also an observation deck and a store.
