In Japanese tradition, the shrine visit that introduces a newborn to a Shinto kami soon after birth is miyamairi.
Miyamairi is a first shrine visit for a baby. Family members take the infant to a Shinto shrine, where a priest may offer prayers or perform a blessing. The visit expresses gratitude for the birth and asks for the child’s health and protection.
The traditional timing is often described as about one month after birth, although the exact day differs by region, family custom, and the baby’s or mother’s health. Modern families may choose a convenient date.
Miyamairi is separate from okuizome. Okuizome is the symbolic first-meal ceremony held around 100 days, while miyamairi centers on a shrine visit and Shinto blessing.
