If you’ve ever stopped scrolling at a photo of snow-covered wooden inns glowing under gas lanterns — that’s likely Ginzan Onsen. One of Japan’s most atmospheric hot spring towns, it sits in the mountains of Yamagata Prefecture and is especially breathtaking in winter. On this visit, I stayed at Nagasawa Heihachi, the landmark inn right at the heart of the street.
Why Nagasawa Heihachi stands out:
- An iconic location at the center of the Ginzan Onsen streetscape
- Spacious all-wood private baths — available any time, no booking needed
- Refined kaiseki dinner featuring local Obanazawa wagyu beef

Nagasawa Heihachi
Getting There
By train from Tokyo: Take the Yamagata Shinkansen to Yamagata (~2.5 hrs), transfer to a local train to Obanazawa (~40 min), then a bus to Ginzan Onsen (~25 min). Total: around 3.5–4 hours. The Shinkansen is covered by the JR East Tohoku Pass.
By car: Exit at Higashine IC on the Tohoku Chuo Expressway, head toward Obanazawa, then follow signs east. Park just above the town — cars cannot enter the onsen street itself. Call the inn on arrival and staff will come to meet you.
The Street — Day and Night
Stepping into the onsen street is a genuine wow moment. Taisho-era wooden inns line both sides of the Ginzan River, and in February the whole scene is buried in snow. After dark, gas lanterns switch on and steam rises from the hot spring vents in the street — the atmosphere becomes something else entirely.
The snowy streetscape — one of Japan’s most iconic views.
After dark, the lanterns and steam transform the street completely. There’s also a free foot bath (ashiyu) in the middle of the street — worth a stop.

The Room
Rooms are traditional tatami-style with futon bedding — classic ryokan comfort. The interior is immaculately maintained, far newer-feeling than the exterior suggests. Wi-Fi, private toilet, yukata robe, and towels are all provided.
The view from my third-floor room — rooftops buried in snow.
🛏 New to ryokan stays?
In a traditional Japanese inn, you sleep on a futon laid on tatami mat flooring. You’ll receive a yukata (casual cotton robe) to wear around the inn and to the baths. Settle in and enjoy it — this is the experience.
The Hot Springs
There are three options: one shared indoor bath (men’s/women’s separate), and two private baths (kashikiri) available to guests at any time on a first-come, first-served basis.
♨ What is gensen kakenagashi?
All baths use pure, undiluted spring water flowing directly from the source — no reheating, recycling, or additives. This is the gold standard in Japanese hot spring culture.
| Water Type | Sulfur-Sodium Chloride · Sulfate Spring |
|---|---|
| Source Temperature | 66.5°C / 151.7°F |
| pH | 6.6 (near neutral) |
| Color / Scent | Clear, colorless — very mild and faintly mineral |
Large Private Bath ★ The Highlight
A spacious all-wood private bath — completely yours for as long as you like.
A generously sized all-wood tub under a high ceiling, completely private, with a small window looking out over the snowy street. The combination of the wood, the minerals, and the silence outside is deeply restorative. Time disappears here in the best possible way.
🛁 Tattoo policy
Visible tattoos are generally not permitted in the shared bath. However, the private baths are fully enclosed and used individually — guests with tattoos can enjoy them freely without any issue.
Dinner & Breakfast
The kaiseki dinner — refined, varied, and beautifully balanced.
Dinner is a traditional kaiseki multi-course meal, with dishes arriving in sequence.
The standout is Obanazawa wagyu beef steak — a local Yamagata variety, served in a modest but excellent portion. Nothing heavy; everything considered.
Breakfast is a classic Japanese set, simple and well-seasoned.
Final Thoughts
Ginzan Onsen exceeded every expectation, and Nagasawa Heihachi is a wonderful base to experience it from. The private baths alone are worth the trip. At ¥25,000–35,000 per person including meals, it’s not a budget stay — but for a one-night immersion into traditional Japanese inn culture, it delivers.
This stay is a great fit if you:
- Want an authentic traditional ryokan experience
- Are visiting in winter for the snowy streetscape
- Prefer private baths — or have tattoos
- Are looking for something memorable off the standard tourist trail
If you go, make it winter. The snow makes everything feel exactly as it should.
