Yamanashi is Japan’s largest and most famous wine-producing region, responsible for nearly 40% of the nation’s annual production of wine. The region is located on the main island of Honshu within a landlocked area. There is an extremely fertile valley in Yamanashi as famous for its peaches and plums as its grapes. This region, surrounded by some of the tallest mountains in Japan – including the famous Mt. Fuji – is now the focal point of high-quality wine production in Japan.
