Sauna

The next sauna hut we built: "The next sauna!"

This sauna hut was completely self-built, driven by dedication, passion, self-study, and research, with the aim of creating the ultimate sauna.

A small wooden sauna hut nestled in the forest, by the river.

A Finnish-style sauna heated with firewood.

All you'll find here is the forest, the river, and the sauna.

A place to simply enjoy outdoor sauna in nature.

This small "sauna hut" stands alone along a clear stream in the forests of Gunma. It was handcrafted, modeled after primitive Scandinavian sauna huts.

The heat source is a wood-burning stove. While watching the flickering flames and listening to the crackling of the firewood, you can enjoy a relaxing sauna experience, slowly working up a sweat with the gentle heat of the flames.

The sounds of the river can be heard from inside the sauna room, creating a relaxing sauna experience.

Enjoy the dimly lit sauna hut, the scent of wood and smoked firewood, and the relaxing flow of time. The sauna is reserved for private use by the hour, allowing you to enjoy a quiet sauna experience.

Enjoy a special "private sauna" experience with a loved one, fellow sauna enthusiasts, or your partner.

The cold bath is right in front of you, in the clear stream. You can dip into the soft, exquisite natural water in just 5 seconds.

A variety of cold baths with a variety of waters unique to a natural river.

Enjoy a natural cold bath in your preferred location: letting yourself go with the flow in shallow waters, relaxing in a deep pool, or splashing water over your head from a small waterfall.

Immerse yourself to your heart's content in the extraordinary natural cold bath that only a river sauna can offer.

An outdoor sauna with scenery that changes with each season, the scent of the wind, the rustling of plants and insects, the chirping of birds and the cries of deer.

Gaze at the greenery, listen to the sound of the wind, stop your thoughts and escape from the hustle and bustle.

Experience the relaxing outdoor sauna at "kanrano sauna," distancing yourself from noise.

A sauna is a "journey into your inner self." If you're ready...

We look forward to seeing you.

The flow of time throughout the day and the differences between each option.

Morning sauna: A soothing sauna experience, with the quiet, crisp morning weather, the awakening chirping of birds, and the beautiful voices of stag frogs.

Afternoon sauna: Enjoy a pleasant sauna time surrounded by the beauty of sunlight filtering through the trees, the contrast between the shadows and light of the leaves cast on the river surface, and the scent of the forest carried by the breeze.

Dusk to night sauna: The beauty of twilight as the setting sun casts shadows in the forest and streaks of orange light across the river surface. A sudden mountain "droplet" greets the dark riverside with lamplight.

Moonlight illuminates the trees, and stars twinkle in the dark sky, creating a fantastical sauna experience.

Rainy sauna: When you leave the sauna room, raindrops caress your skin, providing a pleasurable natural shower.

The raindrops that hit you when you turn your face toward the sky while immersed in the river are soothing. Feeling the rain on your skin as you bathe in the open air is refreshing. Listening to the sound of rain quietly conveys the charm of nature, making for a rewarding sauna time.

The outdoor sauna allows you to experience the charm of nature, whether it's a cold day, a hot day, a sunny day, a slightly cloudy day, or a rainy day, and the unique characteristics of each weather and temperature and climate.

At times like these, you'll feel truly glad that you discovered a sauna,

and we hope you'll understand the meaning of creating a sauna in nature.
