About Shiga
- Producers listed
- 2
Shiga Prefecture, home to Japan's largest lake, Lake Biwa, is a small but distinctive wine region in the Kansai area. Vineyards cluster around the lake's southern and eastern shores, where the vast body of water moderates temperatures and reduces frost risk, creating a workable microclimate for grape growing in an otherwise humid, inland setting. The scene is anchored by two very different producers: Ritto Winery (run by sake brewer Ota Shuzou), which farms its own organic vineyard in Ritto City to make the estate-driven Château Côte de Biwa wines, and Hitomi Winery in Higashiomi, Japan's only winery specializing in unfiltered 'nigori' (cloudy) wine, founded in 1991 by former apparel executive Reizo Zushi. Together they represent Shiga's character: small-scale, hands-on winemaking that favors organic and low-intervention methods over volume, producing wines that pair naturally with the region's renowned Omi beef and Lake Biwa freshwater fish.

ヒトミワイナリー
Hitomi Winery
Hitomi Winery is a pioneering natural wine producer in Higashiomi, Shiga Prefecture, on the eastern shore of Lake Biwa. Founded by Reizo Zushi in 1991 after he stepped down as president of an apparel company at age 60, the winery has produced only unfiltered, cloudy 'nigori' wine since 1994 — bottling each vintage with its natural lees intact rather than clarifying it away. Made entirely from Japanese-grown grapes such as Delaware, Muscat Bailey A, Merlot, Chardonnay and Sauvignon Blanc, fermented with wild yeast and largely without added sulfites, Hitomi's wines capture the raw, living character of the fruit. The winery also bakes bread with its own wine yeast and welcomes visitors for tastings.

Ritto Winery
Ritto Winery is operated by Ohta Shuzo Co., Ltd., a sake brewery founded in 1874 and best known for its 'Dokan' label, headquartered in Kusatsu City, Shiga Prefecture. During WWII the company was ordered to grow grapes for military tartaric acid production; after the war it reclaimed the wasteland of Asagarano in Ritto City through a large-scale soil-inversion project ('tenchi-gaeshi') and began serious winemaking in 1949. Roughly 70% of the grapes used come from the winery's own 7-hectare vineyard, farmed organically without herbicides, taking advantage of strong day-night temperature swings and good sunlight near Lake Biwa. The winery grows around a dozen varieties including Cabernet Sauvignon, Chardonnay, Semillon, Merlot, Muscat Bailey A, and the rare disease-resistant Yama Sauvignon and Red Millennium grapes (used by only two wineries in Japan). Wines are released under the single-vineyard 'Asagarano' label as well as 'BIWA WINE', 'Chateau Court de Biwa', and 'Cheval'; the winery was formerly marketed under the name Biwa Lake Winery (Biwako Winery). The chateau building, completed in 2011, houses the winemaking and aging facility on the ground floor and a tasting shop upstairs, with tours available by advance reservation.
