A traditional Japanese celebration that focuses on praying for the safe upbringing and healthy growth of children. The term "Shichi-go-san" literally translates to seven, five, and three years old, reflecting the ages of children being celebrated—specifically, those who are 3, 5, and 7 years old. However, the ages differ between boys and girls: boys typically celebrate at ages 3 and 5, while girls celebrate at ages 3 and 7. This tradition dates back to the Heian period (794-1185) and originated as a rite of passage for the elite before spreading to the general population.
