Pachinko (????) is a device used for gambling and is related to pinball machines. Although originally strictly mechanical, modern pachinko machines are a cross between a pinball machine and a video slot machine. It is said to have been invented sometime after World War II in Nagoya, though the date is sometimes questioned. They are widespread in Japan in establishments called "pachinko parlors", which also often feature a small number of slot machines.
The player purchases a large number of small steel balls which are inserted, in bulk, into the machine. Originally, machines had a spring-loaded lever for shooting the balls, but modern machines use a round "throttle" that merely controls how quickly an electrically fired plunger shoots the balls onto the playfield. The balls then drop through an array of pins, and usually simply fall through to the bottom, but occasionally fall into certain gates which make the machine pay out more balls.
Most current machines include a slot-machine (these are called "pachi-slo"), and the big winnings are ultimately paid not from the balls falling into gates, but from the slot machine matches that follow. In fact, many modern machines do not use the balls at all to determine winnings; they are based strictly on electronic random number generators.
The winnings are in the form of more balls, which the player may use to keep playing or exchange for tokens or prizes such as pens or cigarette lighters. Cash cannot be paid out according to Japanese law, but players can then exchange certain tokens or prizes for cash at small centres located nearby or in a separate room from the game parlor itself. Such pseudo-cash gambling is theoretically illegal in Japan, but from the sheer number of pachinko parlors in Japan, it is clear that the activity is at least tacitly tolerated by the authorities. Because of issues such as verifiability, both Japanese and Western media refrains from explicitly pointing out that every pachinko parlor has a cash payout window, but no pachinko parlor without a cash payout window has ever been documented.
As a quasi-gambling activity, pachinko is widely held to have links to organized crime (specifically the yakuza), as well as to North Korea, which allegedly uses the sizeable population of Pyongyang-aligned ethnic Korean residents of Japan to funnel pachinko earnings.
Pachinko parlors share the reputation of slot machine dens and casinos the world over—garish decoration, over-the-top architecture, the smell of tobacco, the constant din of the machines, and players entranced for hours in their games.
