Domaine Nakajima is a winery founded by Yutaka Nakajima in 2014 in Tomi, Nagano. Tomi is also part of the Chikumagawa Wine Valley, one of the areas where Nagano promotes the wine industry.

When Yutaka was a businessman, he attended cooking classes organised by Le Cordon Bleu, a world-renowned culinary education institution, as a hobby. He became interested in wine as he bought wines to match the dishes he made there. He also attended wine school and eventually qualified as a wine expert. Around that time, he visited a hill of vineyards in Saint-Émilion, Bordeaux, and thought, "If only I could spend the rest of my life in such pleasant vineyards", which inspired him to become a winemaker.

He then moved to Tomi in 2009. Since then, he has trained at Domaine des Bois Lucas in France, which is owned by Junko Arai, a winemaker who makes wines that he likes, as well as at the Bernhard Huber in Germany and Coco Farm & Winery in Tochigi. These wineries were mainly wineries that vinified with wild yeasts.
