Pachinko (????, Pachinko?) is a Japanese gaming device used for amusement and prizes. Although pachinko machines were originally strictly mechanical, modern pachinko machines are a cross between a pinball machine and a video slot machine.

The machines are widespread in establishments called “pachinko parlors”, which also often feature a number of slot machines. Pachinko parlors share the reputation of slot machine dens and casinos the world over — garish decoration; over-the-top architecture; a low-hanging haze of cigarette smoke; the constant din of the machines, music, and announcements; and flashing lights. Modern pachinko machines are highly customizable keeping enthusiasts continuously entertained.

Pachinko machines were first built during the 1920s as a children’s toy, then emerged as an adult pastime in Nagoya around 1930. All of Japan’s pachinko parlors were closed down during World War II, but re-emerged in the late 1940s and have remained popular since then. Taiwan also has many pachinko establishments due to Japan’s influence during their occupation in WWII. Source : wikipedia.org
