Onamuchi-no-kami is another name for Okuninushi, a major deity in Japanese mythology associated with nation-building, agriculture, and healing. According to the Kojiki and Nihon Shoki, he cooperated with the deity Sukunahikona to establish medicine and healing practices for humans and animals throughout the land. He is enshrined at Izumo Taisha and other shrines, where traditions credit him with knowledge of remedies and protection of wellbeing, though such benefits reflect devotional belief rather than verified fact.
