In Japan, there is a celebration for girls when they reach 3 years old and again 7 years old. For boys, it is when they become 5 years old. Our daughter Misaki will turn 7 this school year, so we celebrated her "7-5-3" on November 10th.
Misaki probably doesn't have many fond memories of the experience, with the weight of obi belt that wraps around the kimono, and the hassle of posing for the family portrait. But maybe that's typical of these 7-5-3 events -- it's mostly for the parents.
The next time I'll get to see Misaki wearing a kimono will probably be in 13 years, for her Coming of Age ceremony. So this day was extra-special for me.
