The passenger flow posted in the photo depends on where the store is opened. Generally speaking, shops are near primary and secondary schools and universities, and the daily passenger flow is about 300 people. If it is opened in a shopping mall, the average passenger flow is about 400 on weekdays and about 800 on rest days. Because of being favored by young people, various photo paste shops emerge in an endless stream, and the competition is becoming increasingly fierce. It has been 10 years since photo stickers became popular. It is said that every female middle school student in Japan has 500- 1000 photos, and photo stickers have become their image representatives, even replacing their signatures.
