Kofu Wine Wineries — Japan's Oldest Wine Region

Kofu Basin in central Yamanashi is Japan's premier wine-producing region, responsible for 40% of domestic wine production. The region's viticulture dates to 1877 when two Yamanashi natives returned from studying French winemaking in Bordeaux and established Japan's first modern winery. The basin's climate — hot summers, cold winters, low rainfall, and granite-rich soil — creates conditions similar to European wine regions. The dominant grape variety is Koshu, a white wine grape native to Japan with over 1,000 years of cultivation history.

The Katsunuma district east of Kofu concentrates over 80 wineries within a 10km radius, ranging from century-old family operations to modern facilities with tasting rooms and restaurants. The most prestigious wineries include Chateau Mercian (Japan's oldest, established 1877), Grace Wine (small-batch organic Koshu), and Lumiere Winery (historic tunnel cellars dug in 1885). The region has gained international recognition — Koshu wines now appear on wine lists in European Michelin-starred restaurants.
