Amamikiyo is a foundational deity in Ryukyuan (Okinawan) mythology, revered as the divine ancestress credited with creating the islands of Okinawa and establishing the first sacred sites and communities there. Associated with the sea and cosmic origins, she is sometimes linked to dragon-king (Ryugu-o) imagery tied to the ocean's abundance, which later folk tradition connected to notions of fortune and prosperity. She remains a central figure in Ryukyuan creation narratives and is honored at various utaki (sacred groves) across Okinawa, though her worship reflects indigenous Ryukyuan religion rather than mainstream Buddhist practice.
