Eco-friendly and clean hot bath with heat from fermentation of microorganisms
The Sawdust Bath (Ion House) is a dry, clean hot bath method in which Ohtaka Enzyme Solution is added to conifer sawdust, which is fermented by microorganisms to a temperature of 60-70°C (the temperature you feel is around 40°C), and you bathe in the sawdust bathtub for 10-15 minutes.
What is Ohtaka Enzyme Solution?
IIt is an undiluted plant fermentation solution made from dozens of plant materials mainly from Hokkaido, which are full of vitality, extracted by osmotic pressure of “beet suger(TENSAI-suger)” and then fermented and matured for a long period of time. This undiluted solution is widely used as a raw material for health drinks, cosmetics, pet food, and sawdust baths.
Since its establishment in 1926 by founder Noboru Ohtaka, Ohtaka Enzyme has been manufacturing and selling health foods, cosmetics, quasi-drugs (bath salts), and operating hot bath facilities based on fermented enzyme drinks using 50 kinds of seasonal plants mainly from Hokkaido. We share our knowledge and techniques in person through local dealers and pharmacies, where our products are used to improve health, constitution, and beauty.
