Isojiman Ooigawanomegumi Kawarutoki celebrates the gifts of the Oi River (Ooigawa), the water source that defines Isojiman Shuzo's sake in Shizuoka. The name, meaning roughly blessing of the Oi River, a time of change, suggests a seasonal or transitional character tied to a particular time of year. As a junmai expression, it focuses on pure rice flavor supported by the soft, pristine river water that is central to Isojiman's identity.
