What God Is Enshrined at Koyasu Shrine? — Konohanasakuyahime, Goddess of Safe Childbirth
Koyasu shrines enshrine Konohanasakuyahime — the goddess who gave birth through fire in mythology. These shrines, dedicated to safe childbirth and parenting, can be found across Japan and often share their deity with Sengen (Mt. Fuji) shrines.
Konohanasakuya-hime (Princess Blossoming Brilliantly Like Flowers of the Trees) is the principal deity of Sengen Shrines dedicated to Mount Fuji, enshrined across Japan at shrines known as Koyasu-jinja (Child-Ease Shrines). She represents the blooming of cherry blossoms and serves as the divine protector of childbirth, marriage, and fire prevention.
The Myth of Childbirth in Flames
In the Kojiki, Konohanasakuya-hime proved her fidelity by setting fire to the birthing hut and giving birth safely to three divine children amid the flames. This legend became the foundation for her role as goddess of safe childbirth, child-rearing, and protection from fire.
