Japan’s winemaking identity is defined by two distinctive grapes: the ancient white Koshu and the richly aromatic red Muscat Bailey A. At Winery Tours Japan, we offer visitors a chance to discover these varietals where they grow best—in the vineyards of Yamanashi.
Koshu, a light-skinned grape with over 1,000 years of history in Japan, produces elegant, crisp white wines that pair beautifully with Japanese cuisine. Meanwhile, Muscat Bailey A—developed in the early 20th century—offers vibrant red fruit flavors and is often vinified into light-bodied reds or sparkling rosés.
On our guided Yamanashi winery tours, guests walk through rows of these native vines, learning how Japan’s climate, elevation, and volcanic soils influence their growth. You’ll also visit historic Japanese wineries specializing in these varietals, where knowledgeable sommeliers and winemakers explain the nuances of each style—from fermentation techniques to food pairing suggestions.
Tastings typically include a set of both Koshu and Muscat Bailey A wines, offering a delicious side-by-side comparison. For wine enthusiasts curious about Japan’s place on the global wine map, this experience to discover and enjoy the best wineries in Japan is unmatched.
