Facility Highlights

A Zen sauna retreat set in approximately 8,000 m² of forest at the foot of Mount Myoko.

Sauna-in Niigata Myoko Kogen is a stay-focused sauna retreat created by renovating a former hotel, built around the concept of spending time here as if it were your own private villa.

Surrounded by Myoko’s forests, clear mountain air, deep winter snow, and natural groundwater, the changing seasons themselves become part of the sauna experience.

Sauna

The property features a shared wood-fired container sauna.

Directly in front of the sauna is a large cold-water plunge pool using natural groundwater from Myoko.

Two guest rooms, Eikyu and Eien, also feature private electric saunas exclusively for staying guests.

Stay

The property has seven guest rooms in total. The following six rooms are currently available for booking:

• Eikyu

• Eien

• Hado

• Kido

• Chido

• Shodo

Tendo is currently under preparation and is not available for booking.

The guest rooms currently available for booking are equipped with kitchens, refrigerators, cookware, and tableware.

Whether you are visiting for skiing, remote work, a longer stay, a family trip, or a group getaway, you can enjoy Myoko at your own pace.

Surrender yourself to the silence of the snow and forest.
Step away from everyday life and reconnect with yourself.
Sauna-in Niigata Myoko Kogen is a place created for that journey of renewal.

Concept

for Sauna — The Ideal Sauna Experience Is Shaped by the Environment

“for Sauna” is the philosophy behind Sauna-in.

We see the sauna not simply as a piece of equipment, but as an experience created through the relationship between architecture, materials, nature, and the surrounding environment.

Airflow.
The texture of materials against the skin.
The contrast between light and shadow.
Sounds drifting in from the forest.
The scent of wood and burning firewood.

By considering each of these elements “for the sauna,” we aim to create a deeper and more immersive sense of relaxation.

Nature for Sauna

From this philosophy comes “Nature for Sauna” — an approach that carefully designs the connection between nature, people, space, and awareness.

Sauna-in Niigata Myoko Kogen is one expression of that idea.

Set on approximately 8,000 m² of land, the renovated former hotel is surrounded by the forests at the foot of Mount Myoko, deep winter snow, crisp air, and natural groundwater.

Here, the sauna experience is inseparable from the landscape itself.

Leave the city behind.
Surrender yourself to the stillness of the snow and forest.
Feel the heat, touch the water, breathe the wind, and listen to nature.
Open your senses, quiet your thoughts, and slowly return to yourself.

This is “Nature for Sauna,” experienced in Myoko.

Features & Experience

Heat, water, wind, forest, and snow — Myoko’s natural environment becomes part of the sauna experience.

At Sauna-in Niigata Myoko Kogen, we do not design only the sauna room itself.

We consider the heat, water, surrounding forest, changing seasons, and the way guests spend their time here as one connected experience.

Wood-Fired Container Sauna

The shared container sauna is heated by a wood-burning stove.

The gentle heat of the fire, the sound of burning wood, and the forest visible through the large windows create a sauna experience that feels closely connected to nature.

As the light and scenery change throughout the day, the atmosphere inside the sauna changes with them.

It is not only about heat.

The view, sound, scent, and surrounding forest are all part of the experience.

Natural Groundwater

Directly in front of the container sauna is a large cold-water plunge pool filled with natural groundwater from Myoko.

The local groundwater contains naturally occurring minerals, including iron.

Because of these natural components, the water may sometimes appear reddish-brown or have a mineral-like aroma. This is caused by naturally occurring minerals in the groundwater and does not necessarily indicate a problem with the water quality.

After warming your body in the wood-fired sauna, cool down in water shaped by Myoko’s natural environment.

Sauna heat.
Natural groundwater.
Forest air.

A hot-and-cold experience created by Myoko itself.

Private In-Room Saunas

The rooms Eikyu and Eien are equipped with private electric saunas.

These saunas are reserved exclusively for the guests staying in those rooms, allowing you to enjoy the sauna at your own pace without sharing the space with other guests.

It offers a quieter and more private experience, distinct from the shared wood-fired container sauna.

Guest Rooms

Six guest rooms are currently available for booking:

• Eikyu

• Eien

• Hado

• Kido

• Chido

• Shodo

Each room differs in size, layout, interior design, and maximum occupancy.

The accommodation is suitable for couples, families, friends, and groups, as well as longer stays during the ski season.

The rooms currently available for booking are equipped with kitchens, making them well suited for both short visits and extended stays.

Tendo is currently under preparation and is not available for booking.

Four Seasons in Myoko

Myoko Kogen changes dramatically throughout the year.

Spring
Snow begins to melt, fresh greenery returns, and the forest slowly comes back to life.

Summer
Cool highland air and deep green forests create a refreshing retreat.

Autumn
The mountains turn vivid shades of red and gold, while the crisp air provides a natural cool-down after the sauna.

Winter
Deep snow and profound silence transform Myoko into an extraordinary sauna destination.

Even in the same place and the same sauna, each season creates a completely different experience.

The changing seasons themselves are part of Nature for Sauna.

Shared Spaces

The property also includes shared areas where guests can relax before or after the sauna.

Enjoy the view of the surrounding forest, read, work remotely, or simply spend time with the people you are traveling with.

These spaces are designed to offer a different sense of openness from the private guest rooms.

Restaurant & Bar

The on-site restaurant and bar are currently not operating.

In the future, we aim to create a space where guests can enjoy ingredients from Myoko and Niigata, local sake, and the food culture of Japan’s snow country.

The opening date has not yet been determined.

For the time being, guests should prepare or purchase their own food and beverages.
