The Seikan Tunnel (Japanese: 青函トンネル, Seikan Tonneru or 青函隧道, Seikan Zuidō) is a 53.85 km (33.46 mi) dual-gauge railway tunnel in Japan, with a 23.3 km (14.5 mi) portion under the seabed of the Tsugaru Strait, which separates Aomori Prefecture on the main Japanese island of Honshu from the northern island of Hokkaido.
[5] [6] [7] At 37.9 km (23.5 miles), it has the longest underwater section of any tunnel in the world and is the third-longest railway tunnel in the world. The speed limit for trains through the tunnel is 160 km/h (99 mph). [8] The tunnel is owned and operated by Getlink, formerly Groupe Eurotunnel.

It was the longest underwater tunnel in the world until 1987—when Japan’s Seikan Tunnel linking the islands of Honshu and Hokkaido took the title—and, for more than 100 years, it was the longest mainline railway tunnel within the UK.
