Mars Hosaka Winery: A Taste of Japanese Terroir

Mars Hosaka Winery, a part of Hombo Shuzo, is located in Nirasaki, Yamanashi, a region known as the heart of Japanese winemaking. Established as a brewing base to enhance quality, the winery takes advantage of Yamanashi's rich climate to produce distinctive wines. The winery's location offers breathtaking views of Mount Fuji and the Southern Alps, enhancing the visitor experience. The Mars group may not be widely known outside Japan, but they produce modern red wines that are reminiscent of Australian or New Zealand wines. Chateau Mars also produces fortified and white Koshu wines, which are fruitier and more rounded than similar wines from other Japanese producers. Koshu grapes are well-suited to the volcanic soils and climate of the Yamanashi prefecture. Visitors can take a winemaking tour to learn about the production process and taste the products in the tasting rooms. The visitor building houses a wine bar and shop where guests can sample Mars wines. The shop also offers a selection of original items. The winery was established as a new brewery base in 2017.
