Message from the Owner

Katsunuma is the birthplace of Japanese vine-growing and winemaking.  Katsunuma Jyozo Winery dates back to 1937, when our founder Yoshichika Aruga started his private winery alongside his silk reeling business.  Ever since the beginning, we have been truthful to our principle, gTo produce only the best, even if it is just one barrelh.  We continue our effort in reflecting the local climate and tradition of Katsunuma, while aiming for the world market.


In 2003 and 2004 consecutively, our Aruga Branca Brilhante was the first of the Japanese wines to win the Silver award at Vinalise Internationales in France, and became the forerunner of Japanese wines in the world stage.  Further in 2007, through the partnership with Chateau Pape-Clement in Bordeaux, Aruga Branca Issehara became the first Japanese wine to be exported to the EU.  On the other hand, in pursuit of expressing the full potential of Katsunumafs climate, we recently started our own production of the European variety of vines.  By maintaining controlled yield and artificial selection, we are receiving high acclaim in this field as well owing to our continuous effort. 


We believe that wine is an expression of nature itself, and winemaker is the advocate of such nature.  With our local winemaking tradition of over a century, we have created a wine that is uniquely Japanese.  We will continue our endeavour to bring out the maximum of Koshu grapes, working together with the local vine farmers in the Katsunuma region. 


Our belief in producing world standard wines with 100% Koshu grapes is solid.  We hope the wines will reflect the heart and soul of Katsunumafs terroir.
