Light, elegant, and distinctly Japanese, Koshu white wine is the crown jewel of Japan’s wine industry. Grown primarily in the Koshu Valley of Yamanashi, this pale-skinned grape yields wines that are fresh, minerally, and perfectly suited to the country’s delicate cuisine.
At Winery Tours Japan, we specialize in introducing guests to the full spectrum of Koshu wines—ranging from crisp dry whites to barrel-aged and sparkling styles. Your journey begins in the vineyard, where you’ll see firsthand how the unique terroir and climate influence grape development. Koshu’s thick skins and late ripening make it ideal for Yamanashi’s humid summers and volcanic soils.
From there, we visit several boutique wineries focused on Koshu production. Each winery in Yamanashi offers a different interpretation of this historic grape. Some produce Koshu in stainless steel for purity, while others age it in oak to add depth and complexity. Along the way, you’ll learn how Koshu has evolved from table grape to internationally awarded wine.
Tastings are thoughtfully paired with light Japanese dishes, allowing you to experience the harmony between Koshu’s gentle profile and Japan’s culinary tradition.
