Kyushu, Japan · Remote island, Sea / Beach, Countryside / satoyama
A low, green island of rice paddies, white-sand beaches and over a thousand shrines, an hour by boat from Fukuoka, once home to the 'Iki kingdom' recorded in third-century Chinese chronicles. People come for sea urchin, Iki beef and barley shochu, which the island claims to have invented.
Ferry or plane — Kyushu Yusen boats leave Hakata Port (Fukuoka, 15 minutes by bus from JR Hakata Station): the jetfoil takes 65-80 minutes to Gonoura or Ashibe (about ¥7,000 one way; until at least March 2027 it runs with a single vessel and very few sailings because of a crew shortage, so book ahead) and the ferry about 2h20 (about ¥3,400, one or two sailings a day). Ferries also run from Karatsu Higashi Port (Saga, 1h20 by train from Fukuoka) to Indoji Port in 1h45 (about ¥2,500, four or five a day), and ORC flies from Nagasaki Airport in 30 minutes. On the island a rental car is strongly recommended, as buses are sparse.
Archaeology museum by Kisho Kurokawa, its grass-covered roof blending into the hillside above the Harunotsuji site. Dioramas and original finds explain how the Iki kingdom traded with China and Korea, and the observation room looks down on the reconstructed village. ¥410; 8:45-17:30, closed Mondays.
A shrine on an islet in Uchiumi Bay that can only be reached on foot for a few hours around low tide, along a sandbar and slippery rocks, so check the tide table first. The whole islet is sacred and not even a twig may be taken away. No toilets, parking for ten cars; 7 minutes by car from Ashibe Port.
A fishing-cooperative boat from Katsumoto Port (10 minutes): the cruise circles cliffs and sea caves, and the shuttle drops you on a white-sand beach with emerald water, one of Japan's top hundred. Shuttle return ¥1,000, cruise ¥2,000, combined ¥2,500; departures 9:00-15:30, minimum three passengers. Lifeguards only from mid-July to late August; there is no restaurant, so bring food and drink and take your rubbish home.
Purple sea urchin is gathered by some three hundred free divers and eaten fresh from mid-April to late June; red sea urchin, the priciest and rarely seen outside Kyushu, runs from July to October (Mimasuzushi in Gonoura serves it as a rice bowl at market price around August). Out of season many places serve it preserved or frozen, so ask.
A national Special Historic Site: the moated capital of the Iki kingdom (2nd century BC to 4th century AD), including remains of Japan's oldest known harbour works. A dozen Yayoi-period buildings have been rebuilt, and the guidance centre runs fire-making and jade-bead workshops for kids (9:00-17:00, closed Wednesdays). Free entry.
Only about nine hundred head of Iki beef are raised a year, with fine fat that melts at low temperature, and most of it is eaten on the island, as yakiniku, steak or beef sushi in Gonoura's restaurants. Also look for hikitoshi, a chicken hotpot with broth, vegetables, local tofu and somen noodles that families make for guests.
Iki kagura, a national Important Intangible Folk Cultural Property some 700 years old, is danced only by the island's Shinto priests, with no written score, on a space of two tatami mats. The full version is offered every 20 December at Sumiyoshi Shrine in Ashibe, 14:00-21:00 with a dinner break; in August there is a free public performance in Katsumoto on a varying date. It is a rite: no applause and no flash.
Iki claims to be the birthplace of barley shochu and has had its own geographical indication since 1995: it is made from one-third rice and two-thirds barley. This is the largest of the seven distilleries; the roughly 40-minute guided tour with tasting is free, 9:00-12:00 and 13:00-16:00, booked by phone (closed at Obon and New Year). If you're driving, only non-drivers taste.
In the squid-fishing port at the north end of the island, local women sell dried fish, squid, vegetables and fruit along the shopping street from about 8:00 to 11:00, a habit dating back to barter in the Edo-period whaling days. No fixed closing day, but it doesn't set up in bad weather. Stroll the harbour lanes and Shobogu Shrine while you're there.
A 45-metre sea stack at the tip of the Kurosaki peninsula shaped like a monkey seen from behind, the island's emblem and a good sunset spot. Next to it is the pit of a 1933 coastal battery that mounted two 41 cm guns from the battlecruiser Akagi, recycled under the Washington Treaty; the tunnel is closed off but you can look down into it. 20 minutes by car from Gonoura.
A kilometre of columnar-basalt cliffs on the Hachiman peninsula on the east coast, above an open grassland, with the slender Kannon Pillars rising from the sea, whitened by cormorant droppings. Much of the edge has no railing, so take care with children and in wind. 15 minutes by car from Ashibe.
A small shrine to the moon god at the top of stone steps under cedars, in the middle of the island. According to the Nihon Shoki, its deity was taken to Kyoto in 487 to found the Tsukiyomi shrine at Matsuo, so it is seen as the source of that cult. Quiet early in the day, before the goshuin stamp collectors arrive.
The island's most popular beach: 600 metres of white crushed-shell sand and shallow water, 3 minutes from the airport, in Ishida. Lifeguards, showers, rentals and beach huts only during the official swimming season (18 July to 31 August in 2026). It makes a fine walk outside that season, but unguarded; jellyfish appear in late August.
The island's only hot-spring village, on a north-west bay: salty, iron-rich water the colour of rust, 69°C at source and about fifteen times over the therapeutic mineral threshold. Legend says Empress Jingu bathed the newborn Emperor Ojin here. Public baths ¥400-500, ryokan baths from ¥1,000, and a six-bath pass for ¥1,650.
The island has 24 shrines listed in the tenth-century Engishiki register and over a thousand shrines and wayside altars in all. A drive can link Sumiyoshi in Ashibe (sacred grove, home of Iki kagura), Hakozaki, Tsukiyomi and Kojima. These are working places of worship: enter by the side of the torii, keep quiet and no drones.
The island is almost flat, and the Fukae plain, the second largest in the prefecture, is ideal by e-bike (Iki-chari rental): rice paddies, cattle farms, the Harunotsuji site and the Uchiumi coast with Kojima Shrine. Best in spring and in autumn when the rice turns gold; summer heat is tough.
Founded in 1888 five minutes from Gonoura Port, this distillery makes 'Iki' shochu with spring water from the island's highest hill; you can look round the jar room and shop Monday to Saturday, 9:00-17:00 (closed 1-3 January and 15 August). A handy stop when arriving or leaving via Gonoura.
The island's main town is a small port, but it has a street of izakaya and snack bars where Iki shochu is drunk oyuwari (with hot water) alongside kensaki squid, winter yellowtail or the day's sashimi. They close early and many have no English menu; book a table at weekends or in summer.
Six little Jizo statues in red bibs and caps standing on the shore at Hachigata in Ashibe, submerged up to the chest at high tide. No one knows who set them there: theories include the women divers, dead whales or warding off epidemics. Local people change their clothes; no parking or toilets, 10 minutes from Ashibe Port.
The island's biggest fireworks show: about 2,000 shells over Katsumoto harbour for an hour and a half, 20:00-21:30, with food stalls and free entry. It falls during Obon, when boats and rooms fill with people returning home, so book everything well ahead. Postponed to the next day in bad weather.
The water-sports beach, in Ishida: local operators run sea kayaking, stand-up paddleboarding, snorkelling and try-dives, with a beach bar next door. Book ahead and ask about the wind: northerly storms or typhoons (August to October) cancel everything, just as they cancel the boats to Fukuoka.
In 1274 and 1281 the Mongol and Korean fleets landed on Iki before attacking Hakata and wiped out the garrison. The route links the Babazaki landing beach, the Shinjo battlefield with its Thousand-Dead Mound (Senninzuka), and Shoni Park, with the grave and bronze statue of Shoni Suketoki, the nineteen-year-old defender.
Iki has over 280 burial mounds, more than anywhere else in Nagasaki. Oninoiwaya (late 6th century) has the island's longest stone chamber, 16.5 metres over three rooms; bring a torch to look in from the entrance, in a grove in Ashibe 15 minutes from Gonoura. Combine it with the nearby mounds in Fudoki no Oka park.
During urchin season, Minatoya guesthouse by Ashibe Port shows you how to crack and clean about twenty freshly caught urchins with the tools local fishing families use, then you eat them (¥4,000; ¥500 more with a breakfast rice bowl). Held only in May in recent years, for 1-8 people, booking required, and cancelled if the sea is too rough to fish.
The island's highest point at only 212.8 metres, yet it looks over all of Iki, Tsushima and the Kyushu coast on clear days. Since ancient times a beacon and watch post stood here facing the strait. With little light pollution it is a good stargazing spot at night; 10 minutes by car from Gonoura.
In winter the boats bring few tourists and the fish market its best catch: kanburi (fatty winter yellowtail), hirame (flounder), arakabu rockfish and oysters, as sashimi or shabu-shabu at Yunomoto's ryokan and Gonoura's restaurants. Along with the onsen, it's the best reason to come from December to February.
Captive bottlenose dolphins in a natural inlet closed off with nets beside Katsumoto Port: a training show is included with entry (¥1,000, 9:30-17:00) and paid programmes let you touch, feed or, in summer, swim with them. It is a captive facility with hands-on contact, which many animal-welfare groups advise against; decide with that in mind.
