Natsuyago is a seasonal brand from Izumibashi Shuzo in Ebina, Kanagawa, a brewery built on the philosophy that sake starts with rice and recognized as one of Japan's leading grower-brewers integrating sustainable rice farming with production. The name references the dragonfly nymph that develops in summer rice paddies, connecting directly to the brewery's iconic red-dragonfly trademark and its belief that healthy aquatic ecosystems in paddies produce the best sake rice. The Natsuyago series ranges from mineral, clean junmai genshu to bold, umami-rich expressions using Omachi rice.
