The bridge's height is intentionally restricted to prevent it from disrupting the view of the natural silhouette of Tsunoshima island.
It was one of the longest toll-free bridges in Japan at the time of its completion in 2000.
The emerald-green color of the surrounding water is caused by the depth and the high transparency of the Sea of Japan in this specific cove.
The design includes a slight deviation to loop around the uninhabited island of Hatoshima, which serves as a scenic midpoint.
Tsunoshima Lighthouse, located on the far end of the island, was designed by British architect Richard Henry Brunton.
The bridge is frequently featured in Japanese automotive commercials to highlight driving experiences along coastal routes.
Tsunoshima Bridge is a 1,780-meter-long toll-free bridge connecting mainland Shimonoseki to the remote island of Tsunoshima. Completed in 2000, it is designed to curve around Hatoshima Island to minimize environmental impact and preserve the landscape. The bridge is recognized for its straight, low-profile design that sits just above the emerald-green Sea of Japan. It serves as a primary access route for both local residents and tourists visiting the lighthouse and beaches on the island. The area is prone to strong crosswinds, which occasionally lead to temporary traffic restrictions for high-profile vehicles. The bridge has gained significant popularity as a frequent filming location for Japanese television commercials and dramas.
The elevated observation deck at Amagase Park on the mainland side provides a clear, panoramic view of the bridge spanning the water.
Cross the bridge by bicycle or on foot to better appreciate the water clarity, though be prepared for significant wind exposure.
Check local weather reports for wind speed warnings, as the bridge may close to certain vehicle types during severe gusts.
Visit the Amagase Park viewpoint on the mainland side for the best elevation to photograph the bridge's curve.
Stopping your vehicle on the bridge itself for photos, as it is a major transit artery and parking is strictly prohibited on the bridge deck.
The bridge remains open 24 hours a day, but access may be restricted during extreme weather conditions such as typhoons.
