Tokyo and Kyoto get, by a wide margin, most of the international attention paid to Japan — and most of it is deserved. But Japan is a long, mountainous, island-heavy country, and a handful of distinctive places sit well outside that well-worn circuit. This list covers three: a mountain valley on Shikoku with centuries-old vine bridges, Japan’s largest sand dune field on the San’in coast, and a subtropical UNESCO World Heritage island in the Amami chain.

A note on how this guide was built: Tripvorra researched these places using UNESCO’s World Heritage listing, Japan’s Ministry of the Environment national park pages, and the official tourism sites for Miyoshi City, Tottori and Amami, which are linked in each section. Fees, bus times and ferry schedules change, so check the linked pages before booking.
Quick Answer
- Iya Valley (Tokushima, Shikoku) — a remote mountain gorge with centuries-old vine suspension bridges and thatched-roof hamlets
- Tottori Sand Dunes (Tottori, San’in coast): one of Japan’s largest dune fields, in the country’s least populous prefecture
- Amami Oshima (Kagoshima) — a subtropical island with UNESCO-listed rainforest, mangroves, and reef diving
How We Chose These Three
Each destination had to be overlooked relative to Japan’s headline sites — measured against visitor volumes for Tokyo and Kyoto, not against zero. JNTO publishes prefecture-level data on where international visitors go, and Tokyo and Kyoto rank far above Tokushima and Tottori. Amami has no separate figure because it is counted within Kagoshima Prefecture. Each site also had to be reachable with normal domestic transport — train, bus, ferry, or a short domestic flight — not a local-only secret requiring a guide or private transport.
The 3 Places at a Glance
- Iya Valley, Tokushima Prefecture — steep river gorge on Shikoku, known for its Kazurabashi vine bridges
- Tottori Sand Dunes, Tottori Prefecture — a 16km stretch of coastal sand dunes on the San’in coast
- Amami Oshima, Kagoshima Prefecture — subtropical island with UNESCO-listed forest and coral reefs
1. Iya Valley, Tokushima Prefecture
Iya Valley is a steep, forested gorge in the mountains of western Tokushima Prefecture on Shikoku. In Japan it is often listed, with Shirakawa-go and Shiiba, as one of the country’s “three great secluded regions”. Its best-known feature is the Kazurabashi vine bridges — suspension bridges woven from mountain vines, with a history local tradition traces to Heike clan warriors who reportedly fled here after their defeat in the 12th-century Genpei War. The bridges are rebuilt roughly every three years using the same traditional method, and walking across one, with the river visible through the gaps in the vines underfoot, is the valley’s signature experience.
Beyond the main Kazurabashi bridge, the quieter Oku-Iya double vine bridges, a pair called the Man Bridge and the Woman Bridge, sit deeper in the valley. They close for winter from December to March. The surrounding hamlets still have thatched-roof farmhouses and terraced fields worked on very steep slopes, and the local specialty, Iya soba made from mountain-grown buckwheat, is worth seeking out in one of the small valley restaurants.
Iya Valley is not a secret. Japan’s national tourism organization promotes its vine bridges, international travel media have covered them, and the valley draws domestic hikers and rafting groups on the Yoshino River in summer. What keeps it out of most first-time Japan itineraries is simply logistics — it requires a car or a well-timed bus connection from Oboke Station, and that alone filters out a lot of casual visitors.
| Nearest Hub | Oboke Station (JR Dosan Line) |
| Getting Around | Rental car or local bus |
| Best Season | Spring greenery & autumn foliage |
| Typical Visit | Half-day up to 2 nights |
Good to Know
- Entry: the main Kazurabashi bridge costs 550 yen for adults and 350 yen for elementary school children. The Oku-Iya double bridges charge the same and are closed from December to March.
- Access: JR Dosan Line to Oboke Station, then a local bus or taxi — a rental car gives far more flexibility given how spread out the sights are
- Where to stay: Iyashi no Onsen Kyo and a handful of valley ryokan offer hot-spring stays; at Hotel Iya Onsen, the open-air bath sits beside the Iya River
Vine bridges: watch your footing
The bridges sway and the wooden slats have real gaps — sturdy shoes matter more here than at almost any other stop on this list
2. Tottori Sand Dunes, Tottori Prefecture
The Tottori Sand Dunes stretch roughly 16 kilometers along the San’in coast and about 2.4 kilometers north to south, formed over an estimated 100,000 years by sand carried down the Sendai River and reshaped by coastal currents and wind. Japan’s Ministry of the Environment describes them as the country’s largest sand dunes. The rolling sand ridges against the Sea of Japan look more like a desert than most visitors expect from Japan.
Tottori is Japan’s least populous prefecture, and it sits far from the Tokyo, Kyoto and Osaka route most first-time visitors follow. Activities on-site include paragliding over the dune ridges, sandboarding, and camel rides run by local operators, plus the nearby Tottori Sand Museum, which builds elaborate sand sculptures around a different annual theme.
Early morning and late afternoon are good times to see the dunes, when low light picks out the ridgelines and there are usually fewer people. The Uradome Coast, a short drive east in Iwami Town, offers sea kayaking and small-boat tours among rock arches, caves and islets. The boat tours do not run from December to the end of February.
| Nearest Hub | Tottori Station |
| Getting There | ~20 min by bus from the station |
| Best Season | Year-round; sunrise or sunset light |
| Typical Visit | 2 to 4 hours |
Good to Know
- Entry: free to walk the dunes; paragliding, sandboarding, and camel rides are paid activities run by on-site operators
- Access: JR to Tottori Station, then roughly a 20-minute bus ride to the dunes
- Best time of day: early morning or late afternoon, both for lighting and for smaller crowds
- Nearby: Tottori Sand Museum and the Uradome Coast are both easy add-ons with a rental car
3. Amami Oshima, Kagoshima Prefecture
Amami Oshima is a subtropical island in the Amami chain, administratively part of Kagoshima Prefecture but geographically and culturally closer to Okinawa. In 2021, UNESCO inscribed “Amami-Oshima Island, Tokunoshima Island, Northern part of Okinawa Island, and Iriomote Island” as a World Natural Heritage site, citing the region’s exceptional biodiversity — including the Amami rabbit, a primitive, dark-furred species sometimes called a living fossil found nowhere else on Earth.
The island’s mangrove forest at Sumiyo, often called the Amami Mangrove Primeval Forest, is the second largest in Japan and can be explored by kayak or SUP through the tidal channels. Offshore, coral reefs support snorkeling and diving, and the island has a long textile tradition in Oshima Tsumugi silk weaving, which artisans still dye with the island’s iron-rich mud.
Amami Oshima’s UNESCO listing has raised its international profile since 2021, and interest in the island is growing, so it is no longer undiscovered. It is smaller and less developed than Okinawa’s main island, with fewer resort hotels around its beaches and reefs. Typhoons can hit from early summer into autumn, and local tourism guidance names October as the most typhoon-prone month, so plan around them because they can cancel flights and ferries.
| Nearest Hub | Amami Airport |
| Getting There | Direct flights or Kagoshima ferry |
| Best Season | Spring–autumn; typhoons possible from early summer, most often in October |
| Typical Visit | 2 to 4 nights |
Good to Know
- Access: direct flights to Amami Airport from Kagoshima, Tokyo (Haneda and Narita), Osaka (Itami and Kansai), Fukuoka and Naha. The overnight ferry from Kagoshima takes about 11 hours.
- Best season: spring through autumn for swimming and diving; typhoons are possible from early summer into autumn, most often in October
- Where to go: Amami Mangrove Primeval Forest for kayaking, and the reefs off Kasari Bay or Sumiyo Bay for snorkeling
- Culture: Oshima Tsumugi weaving workshops in Amami City offer a look at the island’s textile tradition beyond its beaches
General Tips for Visiting
These three don’t pair easily into one trip — Shikoku, the San’in coast, and the Amami Islands are far apart, so treat each as its own leg rather than a single itinerary. Iya Valley works well combined with a wider Shikoku loop; Tottori pairs naturally with a San’in coast route that might also include Matsue or Izumo; Amami Oshima is best treated as a standalone island trip given the flight or ferry commitment.
- A Japan Rail Pass covers the JR trains to Oboke Station. To Tottori, the Super Hakuto and Super Inaba limited expresses use a private line between Kamigori and Chizu, so pass holders pay an extra fare of about 2,000 yen. The pass does not cover local buses or rental cars.
- Rural bus schedules in Iya Valley and around the Tottori dunes can be infrequent — check timetables the day before, not the morning of
- Amami Oshima flights and ferries can be affected by typhoons from early summer into autumn, especially in October; build a buffer day into your schedule during that window
Traveling Responsibly at These Spots
- Iya Valley’s hamlets are small, lived-in communities, not open-air museums — keep to public paths and be mindful around private farmhouses
- The Kazurabashi bridges are rebuilt by hand every few years using traditional methods; stick to posted weight limits and crossing guidance
- Tottori’s dunes have been a national natural monument since 1955. Stay out of roped-off areas and follow posted rules. Local volunteers pull weeds there to keep the sand open and moving.
- Amami Oshima’s reefs and mangroves sit inside a UNESCO World Heritage area; use reef-safe sunscreen and keep a respectful distance from wildlife, including the Amami rabbit
Frequently Asked Questions
Less famous. Iya Valley’s bridges have appeared in international travel media, and Amami Oshima’s profile has risen since its 2021 UNESCO listing. What they share is a low visitor volume relative to Japan’s headline cities, not true obscurity.
Can I visit more than one of these in a single trip?
It’s possible but demanding — Shikoku, the San’in coast, and the Amami Islands are spread across different parts of Japan with no direct connections between them. Most travelers will get more out of treating each as part of a separate regional trip.
Do I need a car to visit Iya Valley or the Tottori Sand Dunes?
A car isn’t strictly required for either, but it helps considerably. Both are reachable by train plus local bus, though bus frequency is limited, especially in Iya Valley, where a rental car gives far more flexibility to reach the quieter Oku-Iya bridges.
Is Amami Oshima affected by typhoons?
Yes — the Amami Islands sit in a typhoon-prone part of the Pacific, with typhoons possible from early summer into autumn and October the most typhoon-prone month. Check forecasts before booking flights or ferries in that window and build flexibility into your plans.
Will these places stay underrated?
Not necessarily. Amami Oshima in particular has seen rising interest since its UNESCO inscription, and Iya Valley’s vine bridges continue to draw international media coverage.
Final Thoughts
The three are a mountain gorge with hand-rebuilt vine bridges, Japan’s largest sand dunes, and a UNESCO-listed island with reefs and mangroves that most international visitors to Japan skip. If you’re planning a wider trip built around lesser-known spots, our guides to 15 hidden gems in Europe and 10 underrated travel destinations around the world cover similar ground elsewhere. For more of Japan, our guide to five underrated towns and hot-spring villages covers places reachable by ordinary trains and buses without a car, and our guide to Japan’s onsen towns in winter covers bathing etiquette and snow logistics.
Each of these three requires a bit more planning — a rental car, a flight connection, a checked bus schedule — than a first stop in Tokyo or Kyoto would.
