Oshu Sabon

Rice X Fermentation
The triple-effect of rice bran/koji (rice mold)/yeast
Oshu Sabon is a premium skin care soap which extracts the finest of the power of fermentation, a millennia old tradition from Japan. Fermenstation, founded upon fermentation technology, proudly presents this high-quality soap to those looking for a new experience.

Organic rice from Iwate Japan, pure brown rice Koji (rice mold), combined with rice mash created from the process of fermentation makes our deep moist soap. With abundant natural rice oil, jojoba oil and argan oils inside, our soap will protect your sensitive skin.
Oshu Sabon is strictly handmade. Starting from rice milling, we simply add Koji , yeast and water to the rice and ferment it with care, leaving the rest to the Koji and yeast. No other additives. Just natural fermentation. Our soap is made from the rice mash that is produced as a byproduct during this fermentation process. The Koji is a local rice mold produced in neighboring Akita by Akita Konno, one of the largest rice mold manufacturer in Japan. After years of development, we came up with our present day secret sauce, in making the first-ever premium soap from rice.
