What Is a Rice Bran Enzyme Bath?

A rice bran enzyme bath is a Japanese wellness experience that uses the natural fermentation heat of rice bran.

At KOH Fermentation Retreat in Omoromachi, Okinawa, guests lie in a wooden tub filled with warm fermented rice bran. The heat is not created by directly using electricity or gas. Instead, it comes from the natural fermentation process of rice bran.

The warmth feels different from a sauna or a hot bath.
It is gentle, enveloping, and quiet.

As your body is covered with rice bran, you slowly begin to warm from within. The experience is simple: lie down, breathe slowly, and let your body rest.

For many first-time guests, the texture and warmth of rice bran are completely new. It is not only about sweating. It is also about giving yourself a quiet moment away from the noise of daily life.

KOH offers this experience in a fully private room, so you can enjoy your first enzyme bath at your own pace.
