Yamanashi is the birthplace of the Japanese wine industry and the country's largest and most important wine region. Set in a mountain-ringed basin west of Tokyo, it enjoys long sunshine hours, low rainfall, and wide diurnal temperature swings — ideal conditions for viticulture. The region is world-renowned for the indigenous Koshu grape, which yields elegant, crisp white wines, while Muscat Bailey A produces distinctive reds. Historic districts such as Katsunuma and estates like Suntory Tomi no Oka Winery in Kai City anchor a landscape of more than 90 wineries, from century-old houses to innovative boutique producers, keeping Yamanashi at the forefront of Japanese wine quality.
