One of Japan's most photographed hot spring towns. Gas lanterns on the riverside.
A hundred years of wooden inns.
And a quiet farmhouse in the hills, just down the road.
Ginzan Onsen is one of Japan's most photographed hot spring towns. Built along a narrow river gorge in the mountains of Yamagata Prefecture, its multi-story wooden inns date from the Taisho era (1912–1926).
Gas lanterns line the riverside at night. In winter, heavy snow settles on the rooftops and the river steams. It is a small place — the main street takes about ten minutes to walk. But those ten minutes carry the weight of a hundred years.
Tomaru Hosono is located 20 minutes by car from Ginzan Onsen, in the village of Hosono.
The inns of Ginzan Onsen itself are beautiful, and often fully booked months in advance. When they are at capacity — or when travelers want something different — Tomaru Hosono is an alternative worth considering in its own right.
The classic experience. Book early — especially for winter weekends.
A different kind of stay. The two experiences are not in competition — many guests visit Ginzan by day and return to Hosono in the evening.
The heaviest snowfall. Ginzan Onsen is at its most photographed — gas lanterns reflected in snow-dusted rooftops. The farmhouse at Hosono is quiet under white. Access requires care, but the landscape rewards it.
Snow recedes from the lower elevations first. By April, Iwauchiwa wildflowers spread across the slopes of Mt. Odohsan. May brings the warabi fern season — sansai foraging is one of Japan's most seasonal rituals.
The valley cools at altitude. Hosono sits high enough that summer evenings are genuinely cool — a relief from the heat of the plains. The warabi season extends into June. July marks the first Soba Owner visit.
Foliage arrives on the ridgelines in October. The harvest season follows — soba, mushrooms, taro. The New Soba Festival in October draws locals and visitors. Soba Owner participants return for their final two visits.
Walk the riverside street, particularly at dusk when the gas lanterns are lit. Day visitors are welcome — foot baths are available without an overnight stay. The surrounding hills are accessible by trail.
One of Japan's 100 Famous Mountains. The Hosono Mountain Lovers Association leads guided treks from spring through autumn — wildflower treks in April, ridge traverses in June and October. → View event schedule
Historically a station on the silver and safflower trade routes. The town retains some merchant-era architecture. Local sake breweries are worth a visit — ask us for recommendations at booking.
Zao's crater lake, the Shonai coastline, Yamadera temple — each accessible as a day trip from Hosono. Yamagata is compact enough to explore widely from a single base.
20 minutes by car. Close enough for a day visit, far enough to offer a different kind of quiet. We can advise on transportation — by car, taxi, or arranged transfer.
No. Tomaru Hosono is a private farmhouse rental, registered under Japan's private lodging law (Minpaku). There is no on-site staff; the house is yours for the duration of your stay. Check-in is self-managed via a form and chat communication.
Accommodation does not include meals. The farm restaurant "Kura" in Hosono is available by advance reservation. Experience packages include lunch where noted. We coordinate all bookings on your behalf.
Up to 8 guests. The property is rented exclusively — no other guests share the house. It is well-suited to families, groups of friends, or multigenerational trips.
Yes — Ginzan Onsen is 20 minutes by car. Day visitors are welcome at the onsen street. Many guests combine a day visit to Ginzan with an evening return to the quiet of Tomaru Hosono.
Yes, with appropriate planning. December through March brings significant snow to the Hosono area. We recommend arriving by taxi or with a 4WD vehicle equipped with winter tires. We are happy to advise on transport arrangements at booking.
