The winery "Cfa Backyard Winery" in Ashikaga City, Tochigi Prefecture is located on the grounds of the soft drink factory "Marukyo" that has been in operation since 1950. CFA stands for the climate classification representing a warm and humid climate, and "backyard" comes from the American backyard winery. This winery produces wine in a homely atmosphere. The winemakers are a father-daughter team, with senior winemaker Takashi Masuko, his older sister Haruka, who has supported the establishment of many wineries with him, and younger sister Waka, who brings a new perspective, in charge of brewing.
