Shichi-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. As Shichi-Go-San is not a national holiday, it is generally observed on the nearest weekend.
Shichi-Go-San is said to have originated in the Heian Period amongst court nobles who would celebrate the passage of their children into middle childhood. The ages three, five and seven are consistent with Japanese numerology, which dictates that odd numbers are lucky. The practice was set to the fifteenth of the month during the Kamakura Period.
