Photo sticker booths are a magnet for teenagers at a video arcade in Tokyo. Over three days in mid-March, we met two friends about to graduate from high school; a teen applying makeup to create the appearance she craves; two best friends who attend different schools; and a couple in their 20s. The booths have added many new features since they first appeared in 1995. Why are they still so popular? We asked youngsters at the arcade why these stickers mean so much to them.
