As the largest grape-producing region in Japan, Yamanashi Prefecture refers to itself as the “Grape Prefecture.” Of course, there is also a thriving wine industry, which makes a visit to the region a must for wine lovers. Visit the Domaine Hide winery, which emphasizes the influence of the phases of the moon on its grapes, and has a reputation for particularly delicious red wines. Enjoy wine tasting and be sure to pick up a few bottles for souvenirs before you leave.
