About
Bathers soak in sawdust and rice bran heated by natural fermentation.
Just like when lactobacilli in milk produces a lactic acid, the fermentation process emits heat.
Bathers will soak in baths of up to 67℃. However, due to the low rate of heat transmission by the sawdust, and the high oxygen content between the materials, the temperature is ideal for bathing in for approximately 15-20 minutes. Bathing for this length of time ensures that your entire body is heated, both inside and out.
