The source of the “mother water” used to brew Bijofu is the subterranean flow of the Nahari River, which originates in the forest of Mt. Jinkichigamori in Yanase, the homeland of Yanase cedar, the prefectural tree of Kochi Prefecture. After flowing all the way through the rich nature of green forests, beautiful trees and cool valleys of splashing clear streams, the water finally arrives at our brewery.

Crystal clear water is absolutely necessary for brewing our fragrant sake. But we also need high quality rice. We especially like the rice harvested from fields in Tojo, an area that is registered as a special A grade rice producing district.
