Miyasuhime-no-mikoto is a figure from early Japanese tradition, traditionally described as a consort associated with the legendary hero Yamato Takeru, connected to the region now linked with Atsuta Shrine in Nagoya. She is venerated in association with the shrine's founding narrative, tied to the enshrinement of the sacred sword Kusanagi. Devotion to her has become linked with matters of love and relationships, reflecting her role as a devoted partner in the traditional accounts, though such associations rest on legend and popular belief rather than formal doctrine.
