Iwami Ginzan Guide 2026: UNESCO Silver Mine & Yunotsu

Western Shimane keeps the prefecture’s most distinctive World Heritage site: Iwami Ginzan, a silver mine that in the sixteenth and seventeenth centuries produced a third of the world’s silver yet was worked so carefully that its forested valley and merchant town survive almost intact. It was the first mining site in Asia inscribed by UNESCO precisely for its harmony with nature. Paired with the World-Heritage port onsen of Yunotsu, a night of thunderous Iwami Kagura dance and the Sekishu washi papermakers, it makes two days unlike anywhere else in Japan. This guide covers how to do it, and pairs with our Iwami Ginzan and Yunotsu coast itinerary.

At a glance: Two days based at Yunotsu Onsen — the mine shaft and Omori town, an evening bath and Iwami Kagura on day one; a morning soak, the Sekishu washi workshop and the Iwami coast aquarium on day two. Reach the area by rail to Odacity or Yunotsu, or by car; the Omori mine valley is car-free, walked or cycled. Year-round, though kagura runs Saturday nights.

What makes Iwami Ginzan special

At its peak, this remote valley was one of the richest sources of silver on earth, and the metal it produced flowed into the trade of East Asia and beyond. Yet unlike the scarred landscapes of most historic mines, Iwami Ginzan was worked by hand on a human scale, its tunnels small and its valley reforested, and that is exactly why UNESCO inscribed it in 2007 — as a model of mining in balance with the environment.

The tangible heart of the site is the Ryugenji Mabu, one of the very few of the mine’s hundreds of mabu — hand-dug tunnels — that you can walk into. It is a cool, dripping shaft driven straight into the hillside by miners working with only hand tools and oil lamps in the seventeenth and eighteenth centuries, and the rough chisel marks of the diggers are still visible on the walls. Admission is about ¥410 (approx., 2025), and hours run roughly 9:00–17:00 (to 16:00 in winter).

Omori: the Edo town

The valley below the mine is filled by Omori, a perfectly preserved Edo-era town of merchant houses, samurai residences, temples and a magistrate’s office strung along a single curving street — all part of the World Heritage inscription and almost untouched by modern signage. Its quiet anchor is Gungendo, a celebrated lifestyle brand born here that restored a rambling old merchant house into a flagship store, gallery and café selling natural-dyed clothing and homeware; the courtyard café is the best place in the valley for lunch (roughly ¥1,200–2,000, 2026). Walking the street between the mine and the café — past the apothecary, the sake brewery and the moss-grown walls — is the core of the Iwami Ginzan experience.

A practical note: the Omori valley is closed to private cars. Park at the World Heritage Centre at the edge of town and walk in (about 40 minutes to the mine shaft) or rent a bicycle, which is the easiest way to cover the distance.

Yunotsu: a World Heritage port onsen

A short drive west to the coast brings you to Yunotsu, a tiny hot-spring harbour so historically complete — a single street of wooden inns and bathhouses running down to a sheltered cove that once shipped the mine’s silver — that it was inscribed into the World Heritage site along with the mine itself. It has two historic public baths. Yakushiyu is the larger, housed in a handsome 1919 Taisho-era building with a domed gallery and upstairs café, its single stone tub fed by a strongly mineralised spring rated among the highest quality in the country (about ¥450, 2025). Across the street, the older Motoyu (formally Senyakuto) is a rougher, more local bathhouse whose spring was, by legend, found some thirteen hundred years ago; note it has introduced a partial reservation-member system on some weekday daytimes in 2026.

Stay overnight at a wooden inn on the street — Ryokan Masuya, dating from 1910, is a small, characterful choice with its own hot-spring bath, dinner built around the day’s San’in fish (winter brings the prized nodoguro rosy seabass) and Shimane wagyu. There is no grand resort here; the pleasure is exactly the intimacy of an old port town that empties of day visitors by evening.

Iwami Kagura by night

The night’s highlight is Iwami Kagura, the masked, fast-tempo sacred dance of western Shimane — far more theatrical than the solemn court kagura elsewhere — driven by thunderous taiko drums and flute, with dancers in gorgeously embroidered robes enacting myths of gods and demons. The usual climax is the storm-god Susanoo’s battle with the eight-headed serpent Yamata-no-Orochi, whose long cloth-and-wire bodies coil and spit smoke across the floor.

At Tatsunogozen Shrine in Yunotsu, performances are staged on Saturday nights inside the atmospheric wooden shrine hall, close enough to feel the drums in your chest — an unusually reliable chance to see a living folk tradition that elsewhere appears only at festivals. Tickets are about ¥2,000 with reserved seating (2026); shows run roughly 20:00–21:30 from around April 2026 through March 2027, with some dark dates, and the schedule resets each spring, so confirm the date when you book.

Day two: washi and the coast

The second day takes a morning bath at Yunotsu, then follows the coast to the Sekishu Washi Kaikan inland of Hamada, the centre for Sekishu-banshi — a strong, fine handmade paper whose technique is recognised by UNESCO as Intangible Cultural Heritage and has been carried on here for some thirteen hundred years, made by hand from locally grown kozo mulberry bark. You can watch craftspeople beat, screen and dry the fibre, and try the papermaking yourself, scooping a sheet to keep (experience roughly ¥600–1,000, 2026). It is closed Mondays, and groups should book about two weeks ahead. Break the drive at AQUAS, the San’in region’s largest aquarium and the only one in western Japan with beluga whales — a bright, family-friendly counterpoint to the silver mine and the onsen. For the cultured east of the prefecture, our Matsue castle town and Adachi garden guide covers the castle and the gardens.

Practicalities for 2026

The area is reached by rail on the JR San’in Line — Odacity Station for Iwami Ginzan (then a bus to the Omori valley) and Yunotsu Station for the onsen — or by car, which is far more flexible for linking the mine, Yunotsu, the washi centre and the aquarium. Allow a full day for the mine and Omori, as the car-free valley involves real walking or cycling. Yunotsu is quietest and most evocative once the day visitors leave; time your visit around a Saturday if you want to see the kagura.

FAQ

What is Iwami Ginzan and why is it a World Heritage site? Iwami Ginzan is a former silver mine in western Shimane that produced a large share of the world’s silver in the 16th and 17th centuries. UNESCO inscribed it in 2007 as the first mining site in Asia recognised for its harmony with the surrounding environment, rather than for scale alone — the valley and its merchant town survive almost intact.

Can you go inside the Iwami Ginzan mine? Yes. The Ryugenji Mabu is a hand-dug tunnel open to walk through, about ¥410 (2025), roughly 9:00–17:00. The Omori valley is closed to cars, so you reach the shaft on foot (about 40 minutes from the World Heritage Centre) or by rental bicycle.

Where can I see Iwami Kagura? Tatsunogozen Shrine in Yunotsu holds regular Iwami Kagura performances on Saturday nights, roughly 20:00–21:30, about ¥2,000 with reserved seating (2026). The schedule is set each April with some dark dates, so confirm before you travel.

Is Yunotsu Onsen worth staying overnight? Yes — Yunotsu is part of the World Heritage site and one of the most intact historic onsen towns in Japan, with two centuries-old public baths and small wooden inns. Staying overnight lets you bathe in the evening and morning and see the kagura, after the day visitors have left.

How many days do I need for the Iwami Ginzan area? Two days is comfortable: one for the mine, Omori town and Yunotsu with the kagura, and a second for a morning soak, the Sekishu washi workshop and the coast. A car makes linking the sights far easier than rail and bus alone.
