Chateau Jun is a winery founded in 1979 by JUN Co., Ltd., a prominent Japanese fashion and lifestyle conglomerate, making it one of the pioneering examples of a Japanese apparel company venturing into wine production at a time when such an idea was virtually unheard of in Japan. Located in Katsunuma-cho, Koshu City, Yamanashi Prefecture — Japan's premier wine-growing region — the winery operates its own vineyard of approximately 2 hectares and works with contracted farmers across Katsunuma Town and Hakushu Town in Hokuto City. Chateau Jun produces around 70,000 bottles annually from a diverse portfolio of grape varieties: white wines from Koshu (the Japanese indigenous variety), Semillon, Chardonnay, Sauvignon Blanc, Delaware, and Riesling; red wines from Merlot, Cabernet Sauvignon, Pinot Noir, Muscat Bailey A, Fujinoyume (a Japanese indigenous red variety), Marselan, and others. Winemaking and viticulture are overseen by Yoshiya Nirin, whose philosophy centers on producing honest wines that faithfully reflect the terroir of Katsunuma rather than chasing concentration or power. The winery targets elegance, drinkability, and long-aging potential. Chateau Jun has received four stars at the Japan Winery Award (JWA) for six consecutive years as of 2025 (started in 2020), and their Koshu 2018 was served at the G20 Osaka Summit leaders dinner in 2019. ROUGE 2023 (made from the indigenous Fujinoyume variety) won a Silver at Decanter World Wine Awards 2025 — the first DWWA recognition for a wine made from this variety. The winery also produces a cryo-extraction dessert wine from Koshu grapes and an accessible everyday range called Gabu-nomi Chateau Jun. JUN Group also operates Versailles Resort Farm in Hokkaido, a retirement home for racehorses, and releases special-label wines inspired by celebrated racehorses, reflecting the group's broader lifestyle and culture brand ethos.
