Since its establishment in 1950, the bean paste factory has been supporting Japanese confectionery stores in the suburbs. The sweetness and firmness of the bean paste are adjusted according to the customer's request, such as "I want to use it in josei-gashi" or "I want to develop iced monaka (sweet with sweetened bean paste). Recently, deliveries to bakeries and western confectionery stores have been increasing. The main ingredient, azuki beans, are mainly from Tokachi, Hokkaido, and Dainagon from Koka, grown locally. Each 500g pack of Koshi-an and Tsubu-an can be purchased at the factory and direct sales shop, as well as at the JA-operated Hananokaichi Mizuguchi Store.
