The Seikan Tunnel is a 53.85-kilometer-long railway tunnel linking Honsyu Island and Hokkaido Island of Japan. Figure 1 shows the outline of the Seikan Tunnel. There are three types of tunnel (main tunnel, service tunnel and pilot tunnel) in the undersea section of the Seikan Tunnel.They are 240 m deep below sea level at their maximum and receive a water pressure of a maximum of 2.4 MPa. Pilot tunnels are used for the ventilation of the main tunnel and the drainage of the ground water, and they are very important structures in service of the Seikan Tunnel.

With the maintenance of an undersea tunnel, the volume of water inflow is an important indicator used to identify external changes and must be continuously monitored over a long period of time. For the Seikan Tunnel, it is monitored by integrating data provided by flow meters installed at 27 points (16 points in the main tunnel, 5 points in the service tunnel, and 6 points in the pilot tunnel) and data provided by pumping discharge in three drainage pump stations.

Construction on the Seikan tunnel began in 1964, was completed in 1985, and the Seikan tunnel officially opened to traffic on March 13, 1988. The project connects Hokkaido by crossing the Tsugaru strait (Figure 3).
