IShichi-Go-San (七五三?, lit. "Seven-Five-Three") is a traditional rite of passage and festival day in Japan for three- and seven-year-old girls and three- and five-year-old boys, held annually on November 15 to celebrate the growth and well-being of young children.
The tradition has changed little since the Meiji Period. Boys who are aged three or five and girls who are aged three or seven are still dressed in kimono—many for the first time—for visiting a shrine to drive out evil spirits and wish for a long healthy life.
These children are often photographed in their formal attire, kimono, at a local photography studio to commemorate this special occasion.
