“Hama-Natto Snowball Kamosu” is a reward-style sweet made using whole Hama-natto, a traditional fermented soybean food. Developed for women concerned about menopause, osteoporosis, and nutritional deficiencies, it combines fermented food benefits with soy isoflavones. Made only from carefully selected local ingredients, the product takes the form of a sweet snowball cookie popular with women. It was refined through tastings with female advisors, including healthcare professionals and designers. Inspired by the potential of this historic food, it is intended as a treat for oneself or a thoughtful gift for others.
