Tsunoshima & Motonosumi Guide 2026: The Nagato Coast

The northwest coast of Yamaguchi, around Nagato, holds two of the most photographed sights in all Japan: the Tsunoshima Ohashi, a near-two-kilometre bridge that runs dead straight over impossibly turquoise sea to an island lighthouse, and Motonosumi Shrine, where 123 vermilion torii spill down a green headland to the cliffs above the Sea of Japan. This is the prefecture’s most scenic stretch — a coast of blue water, red gates, windswept capes and quiet hot-spring evenings — and it makes a romantic, slow two days by car. This guide covers how to do it, and pairs with our Nagato coast itinerary.

At a glance: Two days based at Nagato Yumoto Onsen — the Tsunoshima bridge and lighthouse, Kawajiri cape and the cliff-top torii of Motonosumi on day one; an Omijima sea-cave cruise, a Senzaki seafood lunch and the Senjojiki clifftop on day two. A car is essential on this coast. Visit Motonosumi on a weekday in 2026, when weekend and holiday worship is suspended for much of the year.

The Tsunoshima Ohashi: Japan’s turquoise bridge

The image that sells the Nagato coast is the Tsunoshima Ohashi, 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 colour is at its most vivid around midday under strong sun, so time your visit accordingly. At the far western tip of the island stands the Tsunoshima Lighthouse, a slender unpainted granite tower built in 1876 by the British engineer Richard Henry Brunton, the “father of Japanese lighthouses”. It is one of the few stone lighthouses in Japan you can climb, with a spiral stair leading to a gallery and a wide view over the grassy headlands and the deep blue sea.

Motonosumi Shrine: 123 torii to the sea

A drive east along the coast brings you to Motonosumi Shrine, 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, the shrine draws on the Inari tradition and was named by an American broadcaster among Japan’s most beautiful places, which made it famous overnight.

A point of detail worth knowing: in 2019 the shrine formally shortened its name from Motonosumi-Inari to simply Motonosumi Shrine (Motonosumi Jinja), so older guidebooks and maps may use the longer form. 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, and harder than it looks. The combination of red gates, green grass and blue sea is unforgettable, and the cliffs and blowhole reward a short walk.

Important for 2026: Motonosumi has introduced worship and approach suspensions on weekends and holidays from March to November, plus Golden Week (around May 2–10) and Obon (around August 8–16), to manage crowding. Plan a weekday visit to be sure of access, and check the shrine’s current notices before you go.

Kawajiri cape and the wild edge

Between the bridge and the shrine lies Kawajiri, 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. There is little here but the rock, the grass, the wind and the water — which is exactly its appeal, a wild, unhurried counterpoint to the famous bridge and shrine, and a good place to feel how far west this coast runs. At the day’s end the sun sets straight out to sea.

A hot-spring night at Nagato Yumoto

The natural base for this coast is Nagato Yumoto Onsen, the oldest hot spring in Yamaguchi, set along the Otozure River. Once a faded spa town, it was beautifully revived over recent years with riverside walks, design cafes and footbaths under the trees, and it is now the most refined onsen in the prefecture. Its flagship ryokan, Otanisanso, founded in 1876, is the most luxurious place to stay in Yamaguchi — a riverside house of tatami rooms, an expansive bathhouse with many indoor and open-air spring baths, and kaiseki dinners built around San’in seafood and Yamaguchi wagyu.

A note on names: “Otozure” is the river running through the town, not the ryokan, which trips up some visitors. An evening here — a long soak, a multi-course dinner, a stroll along the lit river — is the romantic heart of this route, and Yamaguchi has no international five-star hotel to outclass it.

Day two: Omijima sea caves and the Senjojiki clifftop

For the second day, head to the fishing port of Senzaki and take a sightseeing boat out among the sea-stacks and caves of the Omijima coast. Omijima, the island off Senzaki, is called the “Alps on the sea” for the wild rock scenery of its northern shore — sea-stacks, natural arches, blowholes and caves carved by the Sea of Japan into a cliff line of strange and beautiful shapes. The full circuit takes about eighty minutes and noses into the sea caves on calm days; because the outer course is exposed, rough seas cancel the full circuit, so confirm sailings on the day.

Back at the pier, Senzakitchen, the port’s bright modern roadside station, is the easy lunch stop — its seafood diner serves glistening sashimi bowls and the local squid that Senzaki is famous for, alongside a market hall selling the catch to take home. Finish on the high green grassland of Senjojiki, whose name means “a thousand tatami mats”: a 333-metre headland above the Sea of Japan where the grass runs right to the cliff edge and the islands of the coast lie scattered below. It makes a spacious, uplifting close before the drive back.

Practicalities for 2026

This coast is built for a car, and a car is effectively essential: the bridge, the shrine and the capes are spread along a rural shore poorly served by public transport. The nearest rail access is the San’in Line to Nagato or the area’s small stations, but distances between sights are long and buses infrequent. Rent a car at Shin-Yamaguchi, Hagi or Shimonoseki and build the coast into a wider Yamaguchi loop.

Distances in brief: the Tsunoshima bridge is about 40–50 minutes west of central Nagato; Motonosumi is on the Yuya coast between the bridge and the town; and Nagato Yumoto is inland and east, about an hour from the bridge. The best light for the turquoise water is the middle of a clear, calm day, so consider doing Tsunoshima first and the shrine in the afternoon. For the western city and its famous fugu, our Shimonoseki and fugu guide covers the onward leg.

FAQ

Where is the Tsunoshima bridge and is it free? The Tsunoshima Ohashi is on Yamaguchi’s northwest coast, administratively in the Houhoku area of Shimonoseki, about 40–50 minutes west of central Nagato. It is free to cross, and the classic photo viewpoint is at Amagase Park on the mainland approach.

Do I need a car for the Nagato coast? Effectively yes. The bridge, Motonosumi Shrine and the capes are spread along a rural coast with sparse public transport, so a rental car is the practical way to see them. Pick one up at Shin-Yamaguchi, Hagi or Shimonoseki.

Can I visit Motonosumi Shrine any day in 2026? Not freely — in 2026 the shrine suspends worship and approach on weekends and holidays from March to November, plus Golden Week and Obon, to manage crowds. Visit on a weekday and check the shrine’s latest notices before travelling.

Where should I stay on the Nagato coast? Nagato Yumoto Onsen is the best base, a revived riverside hot-spring town with the prefecture’s most refined ryokan, Otanisanso. It puts you within easy reach of the coast and offers the area’s best onsen and dining.

Is the Omijima sightseeing boat reliable? The boats run year-round from Senzaki, but the full circuit course is cancelled in rough seas because the outer coast is exposed. Check sailings on the day, especially in winter and windy weather.
