The coming of age ceremony is called seijinshiki and it is held on January 15 every year. The day is a national holiday. I don't know when it was started, but the coming of age day has existed since the old days. In the year when we become twenty years old, we attend the coming of age ceremony. Many women attend coming of age ceremony, wearing a kimono .
Some men attend coming of age ceremony, wearing a kimono , too.
Kimono is a traditional and folk costume in Japan. We either buy or rent the kimono . My sister attended the coming of age ceremony two years ago. She bought her kimono in Kyoto. Kyoto is a historic city.
