Discover a 100% Rice Bran Enzyme Bath in Naha, Okinawa

Have you ever wondered how an enzyme bath differs from a regular bath or sauna?

An enzyme bath uses the natural heat produced through the fermentation of organic materials such as rice bran or sawdust. Rather than heating the bath directly with electricity or gas, its warmth is created and maintained through the natural fermentation process.

At KOH Fermentation Retreat, we use finely textured, 100% rice bran.

As you settle into the soft rice bran, your body is gently covered from your feet to your shoulders. The sensation is different from soaking in hot water or sitting in a sauna. It is a uniquely Japanese wellness experience shaped by the natural warmth and texture of fermented rice bran.

The temperature and the way the warmth feels may vary depending on the condition of the fermentation and each guest’s physical condition that day.

At KOH, we do not ask guests to endure excessive heat. We carefully adjust the amount of rice bran and the bathing time while checking how comfortable you feel.

Each guest has a completely private room throughout the experience. From the initial consultation and enzyme bath to the shower and quiet rest afterward, you can relax without worrying about other guests.

Whether you live in Okinawa or are visiting during your travels, KOH offers a peaceful opportunity to step away from your daily routine and experience the natural warmth of rice bran.

KOH Fermentation Retreat is currently preparing to open. The reservation opening date will be announced on our official website and social media once confirmed.
