Eisen Shuzo, located in Fukushima Prefecture, brews under two distinct labels: the wide-distribution Eikawa brand bearing the brewery's name, and the premium Eisen label distributed to a limited network of specialist stores. The name Eisen (榮川) combines the characters for prosperity and river, anchoring the brand in imagery of fortune and natural purity drawn from Fukushima's abundant water resources and rice fields. The sake is characterized by a crisp, dry profile with clean acidity and refreshing lightness typical of Fukushima's refined brewing style.
