300 years of Katsunuma grape-growing behind a small, hand-crafted family winery
Marusan Budoshu (also known as Wakao Kajuen) is a family-run winery and orchard in Katsunuma, Koshu City — the historic heart of Japanese winemaking. The Wakao family has cultivated grapes on this land for more than 300 years, and the winery's own winemaking traces back to before World War II, with the business formally incorporated in 1963. Now led by third-generation winemaker Ryo Wakao, the operation combines a tourist vineyard, Wakao Kajuen, where visitors can pick from roughly 26 grape varieties between mid-August and late October, with small-batch winemaking carried out almost entirely by hand — from fermentation to labeling to sales. Using natural farming methods, Marusan Budoshu focuses on expressing the honest character of each grape variety rather than chasing trends, producing approachable, food-friendly wines such as its signature Koshu Hyaku.
