The Kanmon Straits, a narrow waterway separating Japan's Honshu and Kyushu islands, are spanned by the Kanmon Bridge, which provides panoramic views of the surrounding landscapes. Travelers can walk through the Kanmon Tunnel, an undersea passage that connects the two islands.

The surrounding cities of Shimonoseki and Kitakyushu offer a variety of attractions. Shimonoseki, located at the westernmost tip of Honshu, is known for its seafood, particularly pufferfish, and serves as a gateway to the island of Kyushu.
