Our founder, a third-generation sake brewer from Kyoto, noticed the soft, radiant hands of the master brewers who handled the sake lees (koji). He partnered with a cosmetic chemist to transform this traditional byproduct into a modern skincare staple. We source koji only from designated 'Jyozo' grade breweries in Niigata, known for superior rice quality. Each batch is tested in our ISO-certified lab for purity and pH balance. The formula was refined over 24 months based on feedback from over 1,200 trial users in Japan. It now holds a top-rated position in the 'Natural Face & Body Soap' category on major Japanese e-commerce platforms, recognized for its unique ingredient story and consistent results.

The Handmade Japanese Sake Lees Soap - Rosemary Oil Infusion 100g by Tajima Jozo is crafted with a thoughtfully curated blend of ingredients designed to offer a luxurious and beneficial cleansing experience. At its core, sake lees (sake kasu), a byproduct of sake production, serves as a gentle exfoliant and moisturizer, rich in amino acids and enzymes that help to brighten the skin and improve texture. The inclusion of rosemary oil provides natural antiseptic and anti-inflammatory properties, which can help soothe skin irritations and promote a clear complexion, while its invigorating aroma offers aromatherapeutic benefits. Coconut oil and olive oil are incorporated as primary cleansing agents and emollients, creating a rich lather that effectively removes impurities without stripping the skin's natural oils, thereby maintaining hydration and leaving the skin soft and supple. Sodium hydroxide is used in the saponification process to transform these oils into soap, ensuring a solid bar that cleanses effectively. Additional ingredients such as shea butter may be included to enhance moisturization and provide a protective barrier against dryness. This formulation is particularly beneficial for those seeking a natural, eco-friendly soap that combines traditional Japanese ingredients with herbal infusions to deliver cleansing, nourishing, and soothing effects for various skin types.
