Kanmon Straits Infrastructure Tourism

A journey that includes a tour of the infrastructure that supports the Kanmon Straits in seldom-open areas, and an experience of the natural environment and history of the Kanmon Straits.

The Kanmon Straits area, which lies between Kitakyushu City in Fukuoka Prefecture and Shimonoseki City in Yamaguchi Prefecture, has long been a strategic location connecting Japan with the rest of the world.
Here you will find the world's first undersea tunnel, the Kanmon Bridge that connects Honshu and Kyushu, the Kanmon Road and Pedestrian Tunnel that mark where there are underwater prefectural borders, and the Kanmon Passage where the two prefectures are linked by boat. The Kanmon Straits are known to have one of Japan's three largest tidal currents, so the infrastructure here that links everyday life with the natural environment is the fruit of Japanese technology, which is highly regarded around the world. While Japanese technology is exported and shared abroad, on this tour, we showcase the technology that our predecessors built more than half a century ago which is still in use today—even as a tourism destination! Not only can you visit areas that are not open to the public, such as the world's first undersea tunnel and the backstage tour of the national highway tunnel, but you can also enjoy exclusive food experiences from this region.
