The Bridge Everyone Has Seen, the Island Nobody Visits
If you have watched a Japanese car commercial in the last two decades, you have seen Tsunoshima Bridge: 1,780 meters of white ribbon over water so improbably turquoise that first-timers assume filters. Opened in 2000, toll-free, and repeatedly voted Japan’s most beautiful drive, the bridge is Yamaguchi’s calling card. The insider knowledge is simple: the bridge is the appetizer, and the island — plus one nearby noodle heresy — is the meal.
Crossing and What Comes After
The viewpoint first
The classic elevated view is from Amagase Park on the mainland side — shoot the full span before crossing. Light matters: midday sun turns the shallows their famous emerald; overcast flattens everything.
Climb the lighthouse
At the island’s far tip stands the 1876 Tsunoshima Lighthouse, one of Japan’s few “first-class” lenses — and one of the rare historic lighthouses you can climb. The 105-step spiral ends in a gallery over the open Japan Sea. Around it, the twin capes of Makizaki and Yumezaki are wildflower parks with sunset alignments locals plan evenings around.
Slow island time
Shirahama-class beaches with mainland access, a camp ground where tents face open water, and seafood shacks serving uni and seafood-heaped rice bowls in summer. The island empties completely by dusk — sunset from the bridge approach is the closing scene.
The Noodle Heresy: Kawara Soba
Twenty minutes south, Kawatana Onsen is the birthplace of kawara soba — green tea soba noodles griddled crisp on an actual heated roof tile, topped with beef and citrus, dipped in warm broth. Invented here in a hot-spring inn, it is Yamaguchi’s beloved soul food and pairs perfectly with a post-bridge bath in the old spa town.
Practical Notes
- Access: car is honest advice — about 70 minutes from Shimonoseki; by transit, San’in Line to Kottoi Station then local bus to the bridge
- Loop it: Tsunoshima → Motonosumi Shrine → Nagato Yumoto Onsen makes the definitive north-coast day
- Swimming: July–August; the water is as clear as it photographs
- Crowds: summer weekends jam the bridge road — weekday mornings are empty
Drive the bridge, yes. Then stay for the lighthouse stairs, the capes, and noodles cooked on a roof tile — the parts of the postcard everyone else mails home unopened.
