Creating and Sharing Relaxation from Tamba

 While the world continues to change, our approach to sake brewing here in Tamba has remained unchanged.
 Guided by the philosophy of Wajo Ryoshu(和醸良酒)—“great sake is born from harmony”—we believe that sake brewing is, above all, about nurturing people.
 Blessed with a rich natural environment, we craft our sake with the joy of those who drink it always in mind. Across generations, we have aspired to be a brewery that brings a sense of healing, calm, and comfort to every glass.

Tamba — The Land of Our Brewery

Tamba is a basin surrounded by high mountains, known for its wide temperature differences between day and night and across the seasons.
 These natural contrasts give rise to the mystical Tamba Fog （丹波霧）that appears from autumn through winter, and they also nurture agricultural products of remarkable depth—such as Tamba black soybeans and Tamba chestnuts—renowned for their concentrated umami and natural sweetness.

Local Rice

At Nishiyama Brewery, we primarily use rice grown locally in Hyogo Prefecture.
 Our sake rice, Hyogo Kitanishiki (兵庫北錦), cultivated in the Tamba–Tajima region of northern Hyogo, is grown not only by local farmers but also by our own brewers in company-owned rice fields.
 For over 20 years, we have worked together with local elementary school children on rice planting, harvesting, and biodiversity observation. Through these activities, we continue rice farming that stays close to nature and the local community, while nurturing learning opportunities for future generations.

Water That Lives with the Brewery

Since our founding in 1849, the essential brewing water for Kotsuzumi sake has come from the underground stream of the clear Takeda River.
 Drawn from our on-site well known as Chinju Tensen (椿寿天湶), this water is an exceptionally soft water with a gentle mouthfeel, giving our sake both depth of umami and a clean, crisp finish.
 Even during times of flooding in the past, the well continued to flow, and we have long regarded this water source as something sacred to be protected.
 To preserve this vital water for future generations, we actively engage in local environmental cleanup activities.
