In Japanese tradition, the first shrine visit made by a newborn is called miyamairi.
Miyamairi is a Japanese Shinto practice in which a newborn is taken to a shrine for a first visit and presentation. The word combines terms connected with a shrine and visiting. Families traditionally express gratitude for the birth and pray for the child’s health and protection.
Timing varies. In some descriptions, boys traditionally visited around the 31st day after birth and girls around the 33rd day, although contemporary families may choose another date. The baby is commonly carried by a relative, and families may dress formally for photographs and prayers.
Miyamairi should not be confused with okuizome. Miyamairi is a shrine-centered welcome and prayer, while okuizome is a symbolic first-food ceremony held around the 100th day. Neither is a prenatal baby shower; both occur after the child is born.
