The Nagato Coast: Tsunoshima's Turquoise Bridge, the Cliff-Top Torii of Motonosumi & a Yumoto Hot-Spring Night — 2 Days

The Tsunoshima Ohashi is the image that sells the Nagato coast: a 1,780-metre bridge, opened in 2000, that runs almost dead straight and low over water of an astonishing pale turquoise to the island of Tsunoshima. Free to cross, it curves once around a small islet midway, and the lookout at the mainland approach in Amagase Park gives the classic view — the white ribbon of road laid across a sea so clear it looks tropical, with the island green at the far end. It is one of the most filmed and photographed bridges in Japan, used endlessly in car commercials, and on a bright, calm day the colour of the water is genuinely hard to believe. The obvious, exhilarating first stop of a scenic coast drive.

Free to cross, always open. The mainland viewpoint is at Amagase Park (Houhoku, Shimonoseki), about 40-50 minutes by car west of Nagato. Allow about 45 minutes for the view and crossing.

At the far western tip of Tsunoshima stands its lighthouse, a slender unpainted granite tower built in 1876 by the British engineer Richard Henry Brunton, the 'father of Japanese lighthouses', and still in service. It is one of only a handful of stone lighthouses in Japan you can climb, a spiral stair leading to a gallery with a wide view over the island's grassy headlands and the deep blue of the Sea of Japan. The surrounding park has walking paths, sea views and seasonal flowers, and the drive across the bridge and out to the point makes the lighthouse a satisfying destination in itself. A calm, breezy counterpoint to the bridge that brought you here.

Tower climb about ¥300 (approx., 2026); roughly 9:00-16:30, weather permitting. At the west end of Tsunoshima island. Allow about 50 minutes.

Kawajiri is the northwesternmost point of mainland Yamaguchi, a quiet, dramatic cape that few foreign visitors reach. A short walk from the small car park leads out to a grassy headland and a lookout where the land ends abruptly in dark, wave-cut cliffs and the Sea of Japan stretches uninterrupted to the horizon; on clear days the islands of the coast and even distant capes are visible, and at the day's end the sun sets straight out to sea. There is little here but the rock, the grass, the wind and the water — which is exactly its appeal, a wild, unhurried stop between the tourist bridge and the famous shrine, and a good place to feel how far west this coast runs.

Free, always open. A short walk from the car park; about 30-40 minutes by car from Tsunoshima toward Nagato. Allow about 35 minutes.

Motonosumi Shrine is one of the most striking sights in Japan: 123 vermilion torii gates set close together, marching in a winding line for over a hundred metres down a steep green headland to black cliffs where the Sea of Japan crashes into a blowhole below. Founded in 1955, it draws on the Inari tradition and was named by an American broadcaster among Japan's most beautiful places, which made it famous; in 2019 it formally shortened its name from Motonosumi-Inari to Motonosumi Shrine. Its other oddity is the offering box set high in the crossbar of the large entrance torii — said to grant wishes if you can toss a coin up into it, the most elevated saisen box in Japan. The combination of red gates, green grass and blue sea is unforgettable, and the cliffs and blowhole reward a walk. The single most photogenic shrine on this coast.

Free; parking about ¥300/hour. Roughly 9:30-16:30. NOTE: in 2026 worship/approach is suspended on weekends and holidays March-November, plus Golden Week (May) and Obon (August) — visit on a weekday. On the Yuya coast, Nagato. Allow about 50 minutes.

An hour east along the coast brings you to Nagato Yumoto, the oldest hot spring in Yamaguchi, set along the Otozure River and beautifully revived in recent years with riverside walks, design cafes and footbaths under the trees. Otanisanso, founded in 1876, is the town's flagship ryokan and the most refined place to stay in the prefecture: a riverside house of tatami rooms, an expansive bathhouse with many kinds of indoor and open-air spring baths, and kaiseki dinners built around San'in seafood and Yamaguchi wagyu. Yamaguchi has no international five-star hotel, and an evening here — a long soak, a multi-course dinner, a stroll along the lit river — is the gentle, romantic heart of this coastal route.

Flagship riverside ryokan; half-board roughly ¥30,000-60,000+ per person by season (2026). In Nagato Yumoto Onsen. The day's final stop and overnight.

Omijima, the island off Senzaki, is called the 'Alps on the sea' for the wild rock scenery of its northern coast — sea-stacks, natural arches, blowholes and caves carved by the Sea of Japan into a cliff line of strange and beautiful shapes. The best way to see it is from the water, and the Omijima sightseeing boats run circuits from the Senzaki pier out around the cliffs, threading between the rocks and, on calm days, nosing into the sea caves. The full circuit takes about eighty minutes and is the highlight of the second day, a close-up encounter with a coast that is far more dramatic from below than from any road. Sailings depend on the sea, so the rougher outer course is the first thing cancelled in wind.

Circuit about ¥2,200, roughly 80 minutes (approx., 2026); sailings roughly 9:00-17:00 (shorter Dec-Feb). From the Senzaki pier. Full course cancelled in rough seas - confirm same day. Allow about 100 minutes.

Right by the Omijima boat pier, Senzakitchen is the bright modern roadside station of the fishing port of Senzaki, and Senzaki Honmaru, the seafood diner within it, is the easy lunch stop after the cruise. Senzaki has been a fishing town for centuries, famous for its squid, and the kitchen serves it at its freshest — bowls of glistening sashimi over rice, grilled and simmered fish of the day, and the local Kensaki squid in season — alongside a market hall selling the catch and local produce to take home. It is unpretentious, good value and entirely of its place, the natural midday stop between the boat and the clifftop, with the harbour and the island in view.

Seafood bowls and sets roughly ¥1,200-2,500 (approx., 2026); hours about 11:00-15:00 for the diner. Next to the Omijima boat pier in Senzaki. Allow about 60 minutes.

Senjojiki, whose name means 'a thousand tatami mats', is a broad sweep of high green grassland on a 333-metre headland above the Sea of Japan, one of the finest viewpoints on the Nagato coast. The grass runs right to the cliff edge, where the land falls away to the sea and the islands of the coast — Omijima among them — lie scattered below; on a clear day you can see for many kilometres along the shore. There is a small rest house and a campground, and in early summer the slopes are planted with lavender, but the simple pleasure is the open height and the wind off the sea. It makes a spacious, uplifting close to two days on the coast before the drive back.

Free, always open; rest house roughly daytime hours. About 15-20 minutes by car west of Senzaki. Allow about 45 minutes.
