The Kanmon Strait is a historically significant and geographically striking waterway that separates Honshu, Japan's main island, from Kyushu, its third-largest island. It's not just a natural wonder but also a marvel of engineering, featuring the iconic Kanmon Bridge, multiple railway and highway tunnels, and notably, a pedestrian tunnel that allows visitors to walk between the islands beneath the sea. This strait has played a crucial role in Japanese history, including famous battles, and continues to be a vital shipping lane.
Visitors consistently praise the unique experience of walking through the Kanmon National Highway Tunnel, which is free of charge and connects the two islands. Many highlight the scenic beauty, especially around sunset, when the Kanmon Bridge is illuminated and the sky turns orange. Reviewers also enjoy watching the steady stream of large ships navigating the narrow strait. The area offers a blend of natural beauty, historical sites, and modern infrastructure, making it an engaging destination for those interested in both engineering and scenic landscapes.
To make the most of your visit, consider spending 2-3 hours exploring the area. The best time to visit is in the late afternoon to catch the sunset views, which are frequently mentioned as spectacular. Bring comfortable walking shoes if you plan to traverse the underwater tunnel, as it's a considerable walk. While the tunnel itself is free, some nearby attractions or observation decks might have fees. Reviewers suggest visiting both during the day and at night for different perspectives of the bridge and strait.
The Kanmon Strait area is well-connected. From Mojiko Station, you can walk to the tunnel entrance, which takes about 20-30 minutes, passing by the retro waterfront and Norfolk Square. Alternatively, bus service 74 runs from Mojiko Station to the tunnel entrance, though its frequency might vary. For those arriving by car, there are opportunities to stop along the way to visit local sights. Trains and buses offer easy connections, and the area is accessible from both the Honshu (Shimonoseki) and Kyushu (Mojiko) sides. The pedestrian tunnel is specifically for walkers and cyclists (who must push their bikes).
A common complaint is the potential for long walks between attractions if relying solely on foot, especially if the retro railway is not operating. To mitigate this, check bus schedules in advance or consider using a car if you wish to explore multiple points of interest along the strait. Some visitors also note that while the strait itself is impressive, the immediate surroundings might require some walking to reach the best viewpoints or historical sites.
