Hatsumiyamairi presents a newborn to the kami of the district it will grow up in, conventionally on the thirty-first day for boys and the thirty-second or thirty-third for girls, with wide regional variation. The family goes to the shrine, sits inside the worship hall, and the priest reads a norito naming the child. Traditionally the paternal grandmother carried the infant, because the mother was still in a state of post-childbirth pollution and could not enter — a rule most shrines have quietly abandoned and some have not. The child is dressed in a formal kimono draped over whoever carries it. What matters structurally is that this is the first act of parish membership and it is determined by address: you are presented to the kami of where you live, not to a congregation you or your parents chose. Many families now do it wherever is convenient or photogenic, which the priests notice.
