Tsunoshima Bridge, a 1,780-meter span connecting the small island of Tsunoshima to the Hohoku coast north of Shimonoseki, is one of the most photographed drives in Yamaguchi — a straight ribbon of road running low over strikingly clear turquoise water for almost its entire length, free to cross and toll-free. It sits about 90 km northwest of Yamaguchi City (roughly 1 hr 45 min by car) but only about 30 km, or 45 minutes, north of central Shimonoseki, making it a natural pairing with a Shimonoseki-based day or an extension of a Nagato/Motonosumi trip along the coast. No direct bus reaches the bridge from Yamaguchi City; the JR San'in Main Line to Kottoi Station followed by a taxi is possible but slow, so a rental car is by far the most practical way in.
The classic experience is simply driving (or cycling, for the more energetic) across the bridge itself, with a roadside parking area partway along offering the best angle for photographs of the road curving over the water. On the island side, Tsunoshima's main beach — known locally as Cobalt Blue Beach for its clear, pale-turquoise water over white sand — has swimming, snorkeling, and basic shower facilities in season (roughly June-September), while the Shiokaze no Sato rest area near the beach has food stalls, restrooms, and orientation information for exploring further.
Beyond the beach, a scenic drive continues to the far end of the island for Tsunoshima Lighthouse, a still-operating Meiji-era stone lighthouse open to visitors for a small fee, with coastal walking paths and dramatic sea-cliff views nearby. Seafood is the natural lunch choice, with restaurants near the bridge and on the island serving fresh catch, including sea urchin (uni) in season, a local specialty around the Hohoku coast.
Because the water's clarity and color are the main draw, visiting on a sunny day between late spring and early autumn makes the biggest visual difference; the bridge itself is scenic in any weather, but the turquoise effect that makes Tsunoshima famous depends heavily on sunlight and calm conditions.

Frequently asked questions
Is there a toll to cross Tsunoshima Bridge?
No, the bridge is toll-free, one of the reasons it has become such a popular scenic drive.
Can Tsunoshima Bridge be reached without a car?
It is difficult — no direct bus runs from Yamaguchi City, and the closest station, Kottoi, still requires a taxi for the final stretch to the bridge, so a rental car is strongly recommended.
Why does the water look so turquoise?
The shallow water and pale sandy seafloor around Tsunoshima reflect sunlight in a way that produces a strikingly clear, turquoise color on sunny days, especially visible from the bridge and Cobalt Blue Beach.
What else is there to do on Tsunoshima besides the bridge?
The island has Cobalt Blue Beach for swimming and snorkeling in season, Tsunoshima Lighthouse with coastal walking paths, and seafood restaurants specializing in local sea urchin.
