Mann's Wines
マンズワイン
Japan's largest Koshu producer and pioneer of Japanese fine wine — their Solaris series has graced G7 summits and diplomatic state dinners. JWA 2025 five-star winery.
Mann's Wines (Manns Wine Co., Ltd.) is one of Japan's most established wineries, founded in 1962 as a subsidiary of Kikkoman Corporation — the legendary soy sauce maker. The name combines 'Man' from Kikkoman with 'manna,' the Latin word for heaven-sent food. With wineries in Katsunuma, Yamanashi (est. 1963) and Komoro, Nagano (est. 1973), they are Japan's largest producer of Koshu grape wines by volume and a pioneer of Japanese fine wine. Their flagship Solaris series, launched in 2001 — named for the Latin word for 'sun' — has been served at diplomatic state dinners including the 2016 G7 Ise-Shima Summit and official receptions hosting foreign heads of state. Mann's Wines has developed its own proprietary grape varieties, including Shinano Riesling (a Riesling x Chardonnay cross registered in 1991) and Asama Merlot. The winery holds Japan Winery Award 2025 five-star status, the top recognition for consistently outstanding quality across multiple wines and vintages.
