Shichi-Go-San (七五三) literally means Seven-Five-Three. It is a traditional rite of passage and festival day in Japan held on November 15 for 3- and 7-year-old girls and 3- and 5-year-old boys. These ages are considered critical in a child's life. At 7 a young girl wears her first obi, while at 5 a young boy wears his first hakama pants in public. The first time boys and girls are allowed to let their hair grow is when they are 3. This day is well known as a day to take pictures of children.
