Sake Kasu

Sake Kasu (Sake lees) are a by-product that remains after the mash is pressed during sake brewing, and are rich in natural moisturizing factors (NMFs) such as amino acids, vitamins, and minerals that are important for moisturizing and firming the skin. It is said that the reason why a master brewer has beautiful hands is because of the power of sake lees to moisturize and protect the skin.

Bringing out the best in sake lees

We then ripen the sake lees at a low temperature to increase the amount of beauty ingredients, remove the moisture and turn it into a powder.We then succeeded in extracting only the beauty ingredients from this, creating a super concentrated extract.

By taking various steps that would normally not be taken, we have created beauty ingredients derived from sake lees that have a powerful skin-beautifying effect.

NAIA's proprietary beauty ingredients

  • Noto matured sake lees powder

    This alcohol-free, matured sake lees powder is made by aging sake lees, which are rich in amino acids, and then freeze-drying them to condense the beauty ingredients.

  • Super concentrated extract of matured sake lees from Noto

    This is a highly concentrated extract made by removing the sugar from aged sake lees powder and extracting only the amino acids and other beauty ingredients.

Material producer

Sakurada Sake Brewery

Sakurada Sake Brewery, a small sake brewery run by a family of four in Suzu City, Ishikawa Prefecture, has a history of over 100 years. In Takojima, a town that once flourished as a fishing town, they have continued to produce sake that is loved by the locals.

Our collaboration with Sakurada Sake Brewery began when we asked them to make sake using organic rice that they had developed in-house. The resulting sake lees contain about four times as much amino acid as normal sake lees, and this is what led to the creation of NAIA skin care.
