Tamayorihime-no-Mikoto is a deity in Japanese Shinto tradition, whose name is often understood to mean a spirit-attracting or spirit-possessing princess, reflecting a role associated with divine spirits taking up residence in a person. She appears in classical mythological genealogies connected to the imperial lineage, most notably as a figure linked to motherhood and the birth of important legendary figures. She is venerated at various shrines across Japan, where she is associated with matters of fertility, childbirth, and feminine beauty, though specific benefits attributed to her worship vary by local tradition and are not uniformly documented in classical texts.
