Pachinko Parlors were common in Japan in the 80s. The store fronts were all glass on the front to allow the passerby to see into the parlor. The windows, doors, and every other uncovered area were lined with flashing lights, attempting to lure customers. I didn't understand the concept of pachinko, but I did play once with a friend.
Pachinko is a pinball machine on steroids. If you look closely at the photo, you will see a tray of small balls. These are the tokens for the machines, much like older slot machines used quarters or tokens. The balls could be "cashed in" for prizes, but not money since gambling was not legal in Japan. Usually, the players collected cigarettes with their tokens.
