When people think of Japan’s most beautiful bridges, many imagine Kintaikyo in Iwakuni or Rainbow Bridge in Tokyo. Yet in western Japan, far away from the big cities, lies a bridge that often surprises visitors with its sheer beauty and simplicity. Tsunoshima Bridge (角島大橋), located in Shimonoseki, Yamaguchi Prefecture, is one of the longest toll-free bridges in the country. Stretching just under 1,780 meters across the turquoise waters of the Sea of Japan, it links the mainland to the small island of Tsunoshima.
Since its completion in 2000, Tsunoshima Bridge has become an icon of Yamaguchi tourism. The combination of emerald waters, white sandy beaches, and a gently curving road that seems to float over the ocean has made it a popular filming location for commercials, TV dramas, and movies. More importantly, it has brought new life to Tsunoshima Island, opening it up to travelers seeking quiet beaches, scenic viewpoints, and fresh seafood.
In this guide, we’ll take you through the history of the bridge, the best viewpoints, what to do on Tsunoshima Island, seasonal highlights, and travel tips to make your visit unforgettable.
History and Background of Tsunoshima Bridge
Before the bridge was built, access to Tsunoshima Island was only possible by ferry. While the island was known locally for its fishing villages and quiet beaches, it remained relatively untouched by large-scale tourism. The construction of Tsunoshima Bridge began in the late 1990s as part of regional development efforts, aiming to boost the local economy and connect the island more closely with the mainland.
The bridge opened to the public in November 2000, immediately attracting national attention for its striking beauty. Its elegant, low-profile design was carefully chosen to harmonize with the natural scenery rather than overwhelm it. Unlike many other large bridges in Japan, Tsunoshima Bridge was built with a gentle curve that follows the shape of the bay, giving travelers uninterrupted ocean views from both directions.
What made it even more attractive was the fact that it was toll-free from the very beginning, allowing visitors to cross at no cost. This accessibility has made it one of Yamaguchi’s most visited attractions, drawing both domestic and international travelers.
Architectural Highlights

At 1,780 meters long, Tsunoshima Bridge is the second-longest bridge in Japan that connects to an isolated island, surpassed only by Okinawa’s Kouri Bridge. The design intentionally stays close to the sea surface, with pillars set deep into the seabed. This low elevation makes travelers feel as if they are gliding just above the waves, creating the illusion of driving across the ocean.
The bridge’s gentle curve is not just for aesthetics, it helps reduce wind resistance and ensures stability during storms. The road also has several sections with slightly elevated viewpoints, making it perfect for photos whether you’re driving or stopping at one of the designated areas nearby.
Best Viewpoints of Tsunoshima Bridge
The bridge itself is stunning to drive across, but some of the best memories are made from the viewpoints around it.
Amagase Park Observatory
Located on the mainland side, this viewpoint offers the classic postcard shot of Tsunoshima Bridge curving over turquoise waters. It’s especially beautiful in summer when the sea glows in shades of emerald and blue.
Tsunoshima Lighthouse Park
On the island side, the historic Tsunoshima Lighthouse and its surrounding park offer elevated views of the coastline, the bridge, and the Sea of Japan. Sunset from this spot is spectacular.
Drone and Elevated Photography
While drone use requires permission in Japan, photographers often find creative angles from hills and higher coastal paths around the bridge. Each season brings a different atmosphere, spring’s soft greens, summer’s bright blues, autumn’s fiery skies, and winter’s dramatic waves.

What to Do on Tsunoshima Island
Crossing the bridge is only the beginning. Tsunoshima Island, though small, offers plenty of natural beauty and local charm.
Relax on Tsunoshima’s Beaches
The island is surrounded by sandy beaches with clear waters. Shiokaze Cobalt Blue Beach is especially popular for swimming and summer barbecues. Families can enjoy calm waters, while photographers capture sweeping ocean vistas.
Visit Tsunoshima Lighthouse
Built in 1876, the Tsunoshima Lighthouse is one of Japan’s oldest Western-style stone lighthouses. You can climb to the top for panoramic views of the bridge and coastline. The attached museum shares its history and role in maritime safety.
Explore Local Cuisine
Seafood is the highlight here. Restaurants near the bridge and on the island serve fresh squid, sea urchin, and seasonal fish. Local dishes such as Ika Somen (squid noodles) are a must-try.
Scenic Drives and Cycling
The island has a coastal road that loops around, making for a leisurely drive or bike ride with frequent spots to stop for photos. Unlike crowded tourist areas, the pace here is calm and unhurried.
Seasonal Highlights

Each season transforms the scenery of Tsunoshima Bridge and its surroundings.
- Spring: The coastal hillsides bloom with wildflowers, and the soft sunlight makes the sea shimmer.
- Summer: Peak season, when the ocean is at its clearest turquoise. Swimmers, divers, and families flock to the beaches.
- Autumn: Clear skies and cooler weather make it ideal for photography. The sunsets in autumn are especially fiery.
- Winter: Strong winds and crashing waves give the bridge a dramatic, rugged feel. Fewer tourists mean a peaceful visit.
Festivals and Local Events
Tsunoshima and the nearby mainland host seasonal festivals, such as summer fireworks displays and local seafood events. These gatherings often take place on the beaches or near the bridge, making them perfect chances to enjoy local culture alongside stunning scenery.
How to Get There
- By Car: From Shimonoseki, it takes about one hour to reach Tsunoshima Bridge. From Hiroshima, the drive is around three hours.
- By Train and Bus: Take the JR San’in Main Line to Kottoi Station, then a local bus to the bridge area. This option takes longer and requires planning.
