What Ozawa Sake Brewery Co. does

Ozawa Sake Brewery Co. (小澤酒造株式会社), operating under the brand name Sawanoi (澤乃井), is a privately held, family-owned Japanese sake brewery founded in 1702 in Sawanoi, Ome City, Tokyo, at the foot of Mt. Takamizu in the Okutama valley. The company produces a full portfolio of premium Japanese sake using the traditional kimoto (生酛) brewing method, leveraging rock-filtered spring water drawn from a cave well over 100 meters deep on Mt. Takamizu. Its product range spans all major grades — junmai daiginjo, daiginjo, junmai ginjo/ginjo, tokubetsu junmai/junmai, honjozo, liqueurs/shochu, plus seasonal and limited releases such as Junmai Hiyaoroshi and Junmai Namazake Sawane. The flagship Tokyo Kurabito (東京蔵人) pure-rice ginjo has accumulated continuous international recognition since 2018, including Kura Master platinum/gold, Wine Glass Sake Award gold (2020, 2022, 2024, 2026), London Sake Challenge gold, and Milano Sake Challenge awards.

Beyond sake production, Sawanoi operates an integrated on-site hospitality and cultural complex that functions as the company's primary distribution and brand-building channel. This includes a brewery tour program (operating since 1966 and among Japan's earliest), a paid sake tasting room, five dining venues (Sawanoien Japanese restaurant, Mamagotoya soba house, Mameraku tofu restaurant, Cafe Shizuku, Akatonbo BBQ area), the Gyokudo Art Museum, the Sawanoi Gallery, and adjacent hiking trails in the Okutama valley. Distribution is exclusively direct-to-consumer and domestic Japan, executed through on-site retail, the Shopify-powered Sawanoi Online Shop (shop.sawanoi-sake.com) with nationwide Yamato Transport delivery, and partnerships with regional tourism bodies (Ome City Tourism Association, Mitake Tourism Association, Ome Chamber of Commerce) and the Musashi Mitake Shrine. The company is led by 11th-generation family ownership under president Mikiwo Ozawa (小澤 幹夫) and chief brewer Shinji Kashimura (樫村 信二), with no external funding, no parent company, and headcount reported at 1-10.

Direct peers
