Tsunoshima Bridge: A Spectacular Drive Floating on Cobalt Blue Sea

Tsunoshima Bridge, spanning to Tsunoshima Island in Hohoku Town, Shimonoseki City, Yamaguchi Prefecture, is about 1,780 meters long and, as a toll-free island-connecting bridge, boasted one of Japan's longest lengths when it opened. The sight of the bridge running straight over the cobalt-blue Sea of Japan is one of Yamaguchi's finest scenic spots, frequently featured in commercials, films, and magazines. Beyond the bridge, a beautiful lighthouse built in the Meiji period awaits travelers.

Highlights

To photograph the bridge's full view, the observation deck at Amagase Park, just before the bridge, is ideal. On clear days the water is remarkably transparent, and the beautiful gradation from emerald green in the shallows to cobalt blue offshore makes the white bridge stand out all the more. The bridge wrapped in the soft light of morning and evening is also fantastical, and it is worth visiting at different times of day.

Rising on Tsunoshima across the bridge is Tsunoshima Lighthouse, first lit in 1876 (Meiji 9). Built entirely of granite by the British engineer Richard Henry Brunton, who devoted himself to lighthouse construction in Japan, it is known as an unpainted lighthouse. In 2020 it became the first active lighthouse designated a national Important Cultural Property. It is one of the few climbable public lighthouses, ascended by an interior spiral staircase, and the grand panorama of the Sea of Japan from the top is exceptional. The surroundings are laid out as a park, and swimming beaches bustle in summer.

Seasonal Enjoyment

Early summer to summer on clear days, when the sea shines its bluest, is the best season. Under strong sunlight, the water's transparency and gradation stand out even more vividly. Nearby is also Motonosumi Shrine, where 123 red torii gates line up toward the sea, and a Sea of Japan scenic course combining it with Tsunoshima Bridge is popular. In winter, crowds settle down and you can quietly enjoy the lighthouse and sea in clear air.

Access and Basic Information

Location: Hohoku Town, Shimonoseki City, Yamaguchi Prefecture (Tsunoshima). Access: Access is basically by car, about 1 hour from central Shimonoseki via National Route 191. Buses and taxis from Kottoi Station on the JR San-in Main Line are also available. Crossing Tsunoshima Bridge is free. Tsunoshima Lighthouse is a climbable public lighthouse with set viewing hours and a viewing donation. Check the official site for the latest information.

Practical Travel Notes

The parking at Amagase Park, the bridge viewpoint, gets crowded in the tourist season and on weekends, so visiting with time to spare is wise. The lighthouse's spiral staircase has steps and narrow footing, so easy-to-walk shoes are recommended. The top is outdoors and can be windy, so take care that hats are not blown away. Tsunoshima's sights, the bridge, viewpoint, lighthouse, and beaches, are spread out, so getting around the island by car is convenient. If you combine it with Motonosumi Shrine, allow half a day or more to tour at a relaxed pace.

A Word of Advice

The greatest showpiece of Tsunoshima Bridge is the view from the observation deck before you cross. Aiming for a time with the sun behind you on a clear day captures the sea's colors most vividly. After crossing, climb Tsunoshima Lighthouse, left by a Meiji-era engineer, and enjoy the grand panorama of the Sea of Japan. Savoring both the bridge's scenery and the historic lighthouse is the real thrill of Tsunoshima.
