At the time of opening in March of 1975, it was the longest railway tunnel in Japan before being overtaken by in 1988 the opening of the Seikan Tunnel. It is also the longest tunnel section on the entire Sanyo/Tokaido Shinkansen line.

Overview

The construction of the new tunnel started as a project to connect Honshu and Kyushu with a high-speed railway. The tunnel was constructed at the shortest section in the Kanmon Strait between Dannoura, Shimonoseki City - Mekari, Mojiku, Kitakyushu. Although the entire Shin-Kanmon Tunnel is 5 times longer, the undersea section is shorter than conventional line Kanmon Tunnel (Kanmon Tunnel undersea bed section is 1,140-metre (1,250 yd) long).

There is a 1,000 km (620 mi) distance marker about 1.8 km (1.1 mi) from the middle point of the tunnel. This is the only 1000 km railway marker in Japan.
