長野
Japan's most acclaimed wine prefecture, with cool mountain climate and dramatic diurnal temperature swings that produce wines of elegance and precision.
Nagano Prefecture is Japan's premier wine region, situated in the heart of Honshu at elevations between 500–900 meters. The region benefits from a cool continental climate with significant diurnal temperature variation, enabling the cultivation of both international varieties and local grapes. Nagano is home to over 70 wineries and is recognized for producing some of Japan's finest wines.

Appellations
Kikyogahara
Kikyogahara is a historic wine-producing area in Shiojiri City, Nagano Prefecture — the birthplace of Japanese wine culture. Situated on a gentle fluvial terrace at approximately 700 meters elevation in the Matsumoto Basin, it overlooks the Northern Alps. The volcanic ash soils and continental climate with cool nights are ideal for Merlot, which has attained world-class recognition from this appellation. Concord and Niagara grapes, long-standing local specialties, continue to be produced alongside European varieties.

Takayama
Takayama Village, nestled in northern Nagano Prefecture at the foot of the Japanese Alps, is one of Japan's most promising emerging wine appellations. Vineyards spread across an alluvial fan of the Matsukawa River at altitudes ranging from 400 to 850 meters, creating a remarkable diversity of mesoclimates within a single village. The cool mountain climate — with its pronounced diurnal temperature swings, low annual rainfall of around 850 mm, and long sunshine hours — closely mirrors the conditions of Champagne and southern Burgundy. Volcanic ash soils (Kuroboku) mixed with sandy loam and gravel ensure excellent drainage and high organic matter content. The first vinifera planting (Chardonnay) dates to 1996, and the village has since become a consistent medalist at Japan's major wine competitions.

Tomi
Tomi (東御市) is a city in eastern Nagano Prefecture, recognized as one of Japan's premier wine-producing areas. Located at 850 meters above sea level on south-facing slopes overlooking the Chikuma River Valley and the Northern Alps, the area enjoys abundant sunshine, low rainfall, and significant diurnal temperature variation — conditions that produce grapes with concentrated flavors, vibrant acidity, and excellent color. The volcanic clay soils provide rich minerality. Tomi anchors the Chikumagawa Wine Valley, an officially designated Japanese wine region.

Obuse Winery
Obuse Winery (Domaine Sogga) is one of Japan's most revered natural wine estates, based in Obuse-machi, Nagano Prefecture. Founded as a sake brewery in 1842 and converted to wine production in 1942, it rose to international recognition under fourth-generation winemaker Akihiko Soga, who trained in Vosne-Romanee (1997) and Chablis/Domaine Long-Depaquit (1998) before returning to Japan. In 2005 the winery went entirely chemical-free; in 2011 it became the first Japanese winery to obtain JAS organic certification for European grape varieties. Its flagship Domaine Sogga range (labeled Vigne Sans Chimie, meaning without chemicals) is made with 100% estate-grown organic grapes, wild-yeast fermentation, whole-bunch pressing for whites, whole-berry fermentation for reds, and bottled unfiltered. The Sogga Pere et Fils tier blends estate and contracted growers. Akihiko Soga is a central figure in the Japanese wine revolution, featured in the award-winning 2018 film Usukeboys. The winery received a 5-star award at the Japan Winery Award (JWA) 2025.
