Japanese children in elementary school all wear the same type of backpacks. The color is determined by which school they attend and it is part of their school uniform. I saw these in a shop and am amazed at the price, 39,000 yen is the equivalant of $464.00! I used to make my children use their $20 JanSport backpacks for several years. They had to be falling apart and beyond repair for me to buy a new one.
