Tenryu River Wine Valley
天竜川ワインバレー
Nagano's newest wine frontier along the Tenryu River
Located in the Ina Valley of southern Nagano Prefecture, between the Central Alps and the Southern Alps, the Tenryu River Wine Valley is the youngest of Nagano's four officially designated Shinshu Wine Valleys, established in 2013 under the Shinshu Wine Valley Initiative. Vineyards are planted on well-drained river terraces and alluvial fans carved by the Tenryu River, at elevations ranging from roughly 650m to 800m across the towns of Ina, Matsukawa, and Miyada. While river-level areas are relatively warm and humid, the surrounding foothills offer a cooler mesoclimate, and winemakers are still experimenting to find the region's identity, including trial plantings of southern French varieties alongside Chardonnay and Merlot. A signature local grape is Yama Sauvignon, a cross between wild Vitis coignetiae (yamabudo) and Cabernet Sauvignon, prized for its deep color, pronounced acidity, and natural sweetness.
Best for: Adventurous drinkers curious about Japan's newest wine frontier and the native Yama Sauvignon grape.
