Founded in 1991 in Numata, Gunma Prefecture, Okutone Winery relocated its vineyards and winemaking to the Akagi Plateau in Showa Village in 2000, drawn by the area's cool climate at roughly 700 meters above sea level. The family-run boutique winery, inspired in style by California's Napa Valley, manages the entire process in-house — from cultivating about 5 hectares of trellised Chardonnay and Merlot vines to fermenting, barrel- and bottle-aging (roughly a year each), and bottling. An on-site restaurant pairs the estate's wines with dishes made from local Showa Village vegetables and milk, and reserved winemaker-led tours take visitors through the vineyards and cellar.
Who Is This For?
For visitors who want a relaxed, hands-on winery experience — vineyard-to-glass touring, tastings, and a restaurant meal paired with estate Chardonnay and Merlot.
