Taking advantage of the power of nature, this sake is aged for eight years in the “Yukimuro”, a low-temperature snow storage facility with a thousand ton of snow in Uonuma, Niigata, one of the snowiest regions in Japan. The long period of storage at a low temperature of around 3 degrees produces a high-quality aged sake with a smooth and elegant flavor while retaining a light and refreshing taste. The “Ha-” of Hakkaisan means eight, and in this case, eight years of aging as well as a “ha, ha, ha” of much happy laughter.
