Kanmon Straits

The Kanmon Straits form a narrow maritime channel between Honshu and Kyushu islands in Japan, linking the Inland Sea with the Sea of Japan. This waterway separates Shimonoseki from Kitakyushu and serves as a busy shipping corridor flanked by bridges, tunnels, and regular ferry traffic.

In 1185, the naval battle of Dan-no-ura unfolded in these waters, ending the Genpei War between the Minamoto and Taira clans. Modern crossings emerged in the 20th century, transforming the passage into a key transport link between the two islands.

The name Kanmon combines syllables from Shimonoseki and Moji, the two coastal cities anchoring both shores. Visitors can watch ships navigate the narrow passage from observation decks on either side, experiencing the constant flow of maritime traffic between the islands.

Three crossing options are available: a bridge for vehicles, two underground tunnels for cars and trains, and regular ferries. Strong tidal currents shape the passage, making observation decks a good choice to see how ships navigate the water.

Each summer, a fireworks festival launches displays simultaneously from both shores, drawing crowds from both cities. The synchronized show uses the short distance between sites to create a shared spectacle over the water.
