Overview
Nagano is Japan's second-largest wine-producing prefecture, with vineyards spread across the Kikyogahara, Chikumagawa, Tenryugawa, and Nihon Alps valleys. The region was granted Geographical Indication status in 2021 and has built its reputation on high-altitude, cool-climate viticulture. Surrounded by peaks over 2,000 meters, Nagano enjoys strong day-night temperature variation, low humidity for Japan, and well-drained alluvial soils that help vines produce grapes with high acidity and clear varietal character.
Wine grape cultivation began in Kikyogahara in 1890 with American hybrids such as Concord, but Nagano's breakthrough came in 1989 when a Kikyogahara Merlot won a major international gold medal. Today the region is known for Merlot and Chardonnay, alongside Cabernet Sauvignon, Pinot Noir, Sauvignon Blanc, Pinot Gris, and the local Ryugan. Nagano wines have been served at G7 and G20 summits, reflecting their rising global profile.
