Nakahora Dairy Farm is a vast farm range located in an area between mountain foothills and arable flat land, in Iwaizumi-cho, Iwate Prefecture. Though there is a milking shed, there are no cattle barns. The cattle live on expansive open mountain pastures (about 130ha) day and night throughout the year. They feed on wild grass and tree leaves, and drink mountain spring water. The farm is very animal welfare-friendly; it follows natural mating and birth cycles and allows the cows two months of breastfeeding – everything from the breeding to raising of the cattle is done in a natural way. This set of three kinds of pure grass-fed butter is made thanks to the mountain’s perfectly chemical-free grass and water.
