Izanami-no-Okami is a primordial creator deity in Japanese mythology who, together with Izanagi, is credited in the Kojiki and Nihon Shoki with birthing the islands of Japan and many of the kami. After her death and descent to Yomi, the underworld, she became associated with death and the boundary between the living and the dead, following a mythic estrangement from Izanagi. Some later traditions and shrine associations link her to marriage and union, though this connection stems from her foundational role as a partner in creation rather than being a defined specialization in the earliest textual sources.
