Kanmon Straits (関門海峡 Kanmon-kaikyō) is the name of the sea between Kitakyushu on Kyushu and Shimonoseki on Honshu. The straits can be traversed by ferry, train (regular and Shinkansen) and road bridge and tunnel. There is also a tunnel for walkers at the narrowest point near the road bridge. The Kanmonkyō road bridge was completed in 1973. It is the 34th longest in the world at 712 metres in length.
From the point of view of tourists and travellers, it may be helpful to consider the Kanmon area as one complete whole. It is a substantial area in size, with many attractions and opportunities for sightseeing on both sides of the straits.
This display is held on August 13 every year.
