Kanmon Strait

The Kanmon Strait (関門海峡) is the stretch of water separating two of Japan's four main islands. On the Honshu side of the water is Shimonoseki[?] and on the Kyushu side is Moji port, now part of Kitakyushu[?] City.

The Kanmon Strait can be traversed in a number of ways, the oldest of which is the ferry. There is also a bridge which carries an expressway. By far the most used method is the Kanmon Tunnel which carries the Shinkansen, trains, cars and even pedestrians.
