Nishi-Izu (Dogashima)

Chubu, Japan · Sea / Beach, Town / small city

Izu's west coast is a string of white tuff islets, sea caves you enter by boat and clear-water coves, with no railway anywhere along it. Here the sun sets straight into the sea with Mount Fuji across Suruga Bay, and the fishing village of Heda serves the largest crab in the world.

The essentials

Getting there

Train + bus — There is not a single train on Izu's entire west coast: you arrive by Tokai Bus, and the last leg is long. From Tokyo the easiest route is the direct Odoriko to Shuzenji (2h05-2h20, about ¥4,500), then the west-coast bus (series W30-W39, towards Matsuzaki): 70 minutes on the express or rapid, up to 90 on the all-stops service, around ¥2,480, roughly one departure an hour between 7:00 and 16:00. One detail that costs money: the Mishima-Shuzenji stretch of the Odoriko is run by Izuhakone, a private company, and no JR pass covers it. The alternative is a Kodama to Mishima (50-55 min from Tokyo) and then the Nishi-Izu express (W38) from bay 4 at the south exit, about two hours to Dogashima; neither the express nor the rapid charges a supplement or requires a reservation - they are coach-style buses with reclining seats. From the south, the bus from Izukyu-Shimoda via Matsuzaki takes an hour and costs ¥1,680, with one or two departures an hour. From Shizuoka the natural route is the Suruga Bay Ferry from Shimizu to Toi (65-75 minutes, ¥3,000 as a foot passenger after the May 2026 increase, three sailings a day) plus 40 minutes by bus to Dogashima. A car changes the trip considerably: the sunset viewpoints, Heda and the Ishibu rice terraces are poorly served, and the last bus on each branch tends to be mid-afternoon. It works fine without one, but only with the timetable in hand. If you plan to move around, the Tokai Bus 2-day area pass (Dogashima-Matsuzaki-Irozaki, ¥3,400 adults, ¥1,700 children) or the all-network one (¥4,900) pay for themselves in two long rides; pass fares are being revised on 1 October 2026.

Frequently asked questions about Nishi-Izu (Dogashima)

What to do in Nishi-Izu (Dogashima): 28 activities

• Cave cruise around the Dogashima islets 0.5 h must-see

  Twenty minutes by boat that take you inside Tensodo, a 147-metre sea cave with three mouths and a hole in its roof that drops a shaft of light onto blue water. ¥1,500 for adults, ¥750 for children; boats leave when full, every 15-20 minutes between 10:00 and 16:00, and only groups of 15+ book ahead. In a swell the boat skips the cave or doesn't sail at all - call 0558-52-0013 after 9:30 on the day.

• Sunset over Suruga Bay 1.5 h must-see

  The whole coast faces west, so the sun sinks into the sea rather than behind a mountain, with Mount Fuji off to the right on clear winter days. The tourist office catalogues the viewpoints by month, because the point where the sun lands shifts through the year: Dogashima itself works September to March, Norihama beach February-April and August-October, and Koganezaki and Sawada Park all year. Get there half an hour early.

• Walking out to Sanshirojima at low tide 1.5 h must-see

  When the tide drops to around 30 cm, a 200-metre gravel spit surfaces between Sawada beach and the nearest of the Sanshiro islets, and you can walk across dry-shod. The window runs from an hour before to an hour after low water; at a tide of 100 cm nothing shows. The town publishes an annual tide table marking the good days: between October and February there are almost no usable daytime low tides, so in practice this is a March-to-September thing. The rock is slippery.

• Sawada Park open-air bath 1 h

  Two pools perched on a crag above Nishina harbour, one for men and one for women, up a flight of steps from the car park. Run by the town: ¥600 adults, ¥200 for children aged 6-11, closed Wednesdays, open 9:00-18:00 from October to February, to 19:00 March-May and in September, and to 20:00 June-August. No soap or shampoo allowed. It's small, and it fills up at sunset.

• Cape Koganezaki and the horse rock 2 h

  A headland of propylite - rock altered by hot water and underground heat - that turns literally golden in the evening light; it has been a Shizuoka natural monument since 1988. On top there's a park with paths, viewpoints and more than three hundred cherry trees that bloom with Fuji behind them, plus a formation shaped like a horse's head that racing people come to for luck. Below, the cove is one of the best dive sites on this coast.

• Dogashima clifftop coastal path 1.5 h

  A kilometre and a half of path along the cliff edge, a good hour, from Dogashima Park to Sawada Park. The highlight is the Tensodo overlook: you lean over the hole in the cave roof and, with luck, a boat slides underneath while the people on board wave up at you. Free, always open, and some stretches run along the edge with no railing.

• Dogashima Fire Festival 3 h only one Friday in late July

  It stages a six-hundred-year-old local story with fire: the young men of the village shoot burning arrows at a pirate ship anchored in the bay until it blows up, and then three thousand fireworks come down over the water. The 59th edition was on 24 July 2026, 20:25-21:00, at Dogashima Park. Free to watch from the shore; reserved plots cost ¥20,000 for roughly four people, parking included.

• Eating deep-sea creatures in Heda 2 h Numazu · 45 min

  Two kilometres out from Heda harbour the seabed is already 500 metres down, and that's where the takaashigani comes from - the giant spider crab, the largest crustacean in the world, boiled whole in front of you here: one crab for two people runs about ¥9,500, and grilled portions go for around ¥3,000. It's fished from autumn to spring; from May to September there's a closed season and restaurants fall back on frozen stock or other species such as mehikari, akamutsu and red shrimp.

• Iwachi beach and the boat-shaped hot spring 3 h Matsuzaki · 25 min

  A white-sand cove closed in by cliffs that locals cheerfully call the Côte d'Azur of the Orient: emerald water and barely any surf, so it works well with small children. In summer they set up Dajure Iwachi right at the water's edge, a hot-spring tub shaped like a boat that you get into in your swimsuit. Matsuzaki's beaches open in 2026 from 18 to 20 July and from 25 July to 16 August, lifeguarded 9:00-16:00; showers cost ¥600 and parking is paid.

• Matsuzaki: namako-kabe walls and Chohachi's plaster reliefs 2.5 h Matsuzaki · 20 min

  The next town along keeps the largest surviving cluster in Japan of namako-kabe - black tiles set in diamond patterns of raised white plaster, built against fire and salt air. Irie Chohachi (1815-1889), a plasterer who modelled coloured reliefs with a trowel, came from here: about 45 of his works are in the museum named after him, and more in the Iwashina School, an 1880 schoolhouse designated an important cultural property.

• Mihama Cape and Heda's Fuji viewpoints 2 h Numazu · 45 min

  A pine-covered sand spit closes off Heda harbour and makes the most perfect natural anchorage on this coast; you can walk it in half an hour, with cherry blossom in March and lilies in June. Above the village, on the road, are the two good viewpoints: Deai Misaki, which takes in the whole harbour with Fuji behind it, and Kirameki no Oka, where the sea glitters against the light. Both are free and have parking, but they're hard to reach without a car.

• Norihama, the Dogashima beach 3 h

  A hundred and fifty metres of sand right at the foot of the islets, with calm water because the rocks break the swell. In 2026 it is lifeguarded from 18 July to 23 August, patrolled 9:00-16:00, with a beach hut, showers and changing rooms; parking is ¥1,000. Outside those five weeks you can still walk on the sand and swim, but at your own risk. Jellyfish start arriving after Obon, around mid-August.

• Sea kayaking into Tensodo cave 3 h booking

  The difference from the tour boat is that a kayak, on a flat day, goes right inside Tensodo and sits still under the shaft of light, where an engine cannot. Several local outfitters run half-day guided trips suitable for beginners and for children from primary-school age, including a sunset version. Book several days ahead; they cancel for wind without argument.

• Snorkelling in the pebble coves: Ukishima and Tagosehama 3 h

  The two stony coves have the clearest water on this coast. Ukishima is a hundred metres of shingle with rock pools at low tide, a beach hut, showers and ¥1,000 parking, plus the Shiosai municipal bath three minutes' walk away. Tagosehama is sixty metres and even clearer, but you must reserve a place in advance and parking is ¥2,000. Both are lifeguarded 18 July to 23 August 2026; water shoes are close to essential.

• Heda shipbuilding museum and deep-sea gallery 1.5 h Numazu · 45 min

  In 1855 the Russian frigate Diana was wrecked off Izu, and her crew built here, with village carpenters, the first Western-style sailing ship made in Japan, which they named Heda. The museum tells that story with pieces from the ship and, in the same building, keeps some three hundred deep-sea fish from Suruga Bay, stuffed and in jars. ¥200 adults, ¥100 for school children, 9:00-16:30, closed Wednesdays.

• Ichi-no-yu hot spring at the Heda roadside station 1.5 h Numazu · 45 min

  The Kurura Heda roadside station has a sodium-calcium hot spring attached, with an indoor pool and an open-air one, for ¥500 adults and ¥250 for primary-school children, open daily 10:00-21:00. Towels aren't included (¥250 for a small one, ¥550 for a bath towel) but you can bring your own, and there's a free footbath on the entrance terrace until 18:00. It's where the afternoon ends for anyone who came to Heda for crab.

• Ishibu rice terraces 2 h Matsuzaki · 30 min

  About 370 stepped paddies held by dry-stone walls, 4.2 hectares in all, hanging above the sea; on clear days you can see Mount Fuji and even the Southern Alps across the water. A group of residents and volunteers brought them back after years of abandonment, and paths run between the banks. The two moments are May, when they're flooded and mirror the sky, and September, with the ears turning yellow. There's no useful public transport: come by car or taxi from Matsuzaki.

• Koibito Misaki, the lovers' cape 1.5 h Izu · 30 min

  Seven hundred metres of path through pines, with steps, out to a balcony over the bay taking in everything from Fuji to Cape Omaezaki. At the end there's a bell couples ring three times while saying each other's name, and the Stella House at the entrance (9:00-17:00, with a café) issues a certificate. Parking is free. It sits on the Toi road, so it fits neatly on the way to Dogashima if you're coming from Mishima on the express bus.

• Kumomi, Senganmon and the Ushitsuki-iwa dive site 3 h Matsuzaki · 35 min

  Senganmon is a rock arch some thirty metres high, opened in an old volcanic vent, once known as the torii gate of the sea; it's a twenty-minute walk from Kumomi beach. Offshore, Ushitsuki rock is one of the best-known dive sites in Izu, with submerged arches and caves, and from the shore Mount Fuji sits straight across the bay. Kayaking is banned inside Kumomi's swimming area.

• Longer coastal and geosite cruises 1 h

  Besides the short cave run, the same operator runs two longer trips further along the tuff coastline: the 30-minute Premium (¥2,400 adults, ¥1,200 children) and the 45-minute Geosite (¥2,700 and ¥1,350), both increased on 1 April 2026. They sail only at weekends and on holidays, at fixed times between 11:00 and 14:00, with the Geosite usually at 13:00 on Sundays. Rough seas cancel them.

• Matsuzaki's rice paddies turned into flower fields 1.5 h Matsuzaki · 20 min only 20 Mar - 10 May

  Between March and May, before the rice goes in, Matsuzaki's farmers sow two and a half hectares of paddy with poppies, African marigolds and daisies, and let people walk the paths between the banks. Right alongside, the Naka River carries some 1,200 cherry trees over six kilometres, blooming in late March and lit at night. Entry is free and there's a stall market of local produce.

• Night in Nishi-Izu: a fish dinner and a dark sky 3 h

  Worth knowing before you arrive: there is no nightlife here. After eight the villages are shut and the few izakaya in Nishina and Matsuzaki have four tables each, so dinner happens at the ryokan, almost always built around fish from the bay, and many places don't even offer a half-board option to skip. In exchange, the lack of light leaves a very clean sky over the sea, and you don't need to go anywhere special for it: just step outside.

• Shiosai-no-yu, the Ukishima municipal bath 1 h

  The town's other bathhouse, three minutes' walk from Ukishima beach, with tubs finished in Izu stone. ¥600 for adults and ¥200 for children, closed Tuesdays and Wednesdays, and normally open only 16:00-20:00 because the mornings are let out for private hire (¥2,000 extra for two hours, booked by noon the previous day). From 30 July to 21 August it opens at 9:00 and closes only on Wednesdays.

• Sunset between the Otago rocks at the equinox 1.5 h only around the two equinoxes

  Otago cove has twin islets just offshore, and only in the weeks around the equinoxes, in March and September, does the sun set exactly through the gap between them. The rest of the year it drops to one side and the effect is lost. It's a small shingle beach with free parking and nothing but toilets; in August it opens as a swimming beach.

• Suruga Bay Ferry, Toi to Shimizu 2 h Izu · 35 min

  Officially it's a prefectural road that happens to run across the sea, and it's the finest way in or out of Izu: 65-75 minutes with Mount Fuji growing off the bow. There are only three sailings a day each way (from Shimizu at 7:40, 11:20 and 14:40; from Toi at 9:35, 13:00 and 16:30). Since 1 May 2026 a foot passenger pays ¥3,000, primary-school children travel free, and a car under 6 m costs ¥5,000 including the driver. Suspended in bad weather.

• Tago's shiokatsuo, Japan's oldest preserved food 1 h booking

  A handful of houses in Tago harbour still salt whole bonito and hang them in the wind to make shiokatsuo, a preserve documented for over a thousand years and still hung on doorways at New Year. Kanesa, founded in 1882, makes it and also smoke-dries katsuobushi by the wood-fire tebiyama method. The shop is open 9:00-17:00 with irregular closing days; to see the workshop you have to phone ahead.

• The sandy beaches for families 4 h

  With children, the sandy, shallow options are Ohama (half a kilometre next to Dogashima, free parking), Crystal Beach at Ugusu (another half kilometre, with a beach hut and a campsite, ¥1,000 parking), Ugusu itself and Arari, the last one in a closed inlet with natural pools. All four are calm. In 2026 Crystal Beach is lifeguarded from 18 July to 23 August and the rest only from 1 to 23 August, 9:00-16:00.

• Toi gold mine 2 h Izu · 35 min

  Japan's second-largest gold mine, worked from the early 1600s until 1965; today you walk a few hundred metres of gallery with figures reenacting pick-and-hammer work, plus a museum and an enormous ingot you can touch. Entry ¥1,200, ¥600 for children, 9:00-17:00 with last admission at 16:30. Gold panning is extra: fifteen minutes for ¥1,200 (¥1,000 children), with registration until 16:20.

What only happens on specific dates
