Koshu Wine & Grape Picking (Katsunuma)
Katsunuma in the Kofu Basin is Japan's oldest wine region, producing the distinctive Koshu white grape โ a thin-skinned variety yielding delicate, citrusy wines unique to Japan. Late August to October is harvest season when dozens of wineries open for grape picking, barrel tastings, and cellar tours. The surrounding basin, ringed by mountains and filled with vine rows, resembles a Japanese Provence.
