Katsunuma Budou no Oka is a hilltop complex in the center of Japan's Koshu Valley, specifically designed as a showcase for local Yamanashi wine production. The facility features an expansive underground wine cellar containing approximately 200 varieties of locally produced Koshu wine. Visitors gain access to the cellar via a standardized tasting cup (tastevin), which allows for self-service sampling of all available vintages. The site also functions as a multi-use leisure destination, incorporating a panoramic hot spring bath, an accommodation wing, and restaurants overlooking the surrounding vineyards. It sits on a prominent elevation that provides unobstructed views of the Kofu Basin and the surrounding mountain ranges. The facility is owned and operated by Koshu City to promote the regional viticulture industry. It acts as a central hub for the local oenology scene, hosting wines that have passed a rigorous quality screening process by the Katsunuma Wine Committee.
