Contra KonamiIf you’ve never heard of the Konami Code, that’s not much of a surprise. First, let’s make sure we all know who Konami is.

The Konami Corporation is a leading Japanese game developer and publisher of toys, trading cards, anime, tokusatsu, slot machines, arcade and video games. Konami is responsible for the following popular game series: Metal Gear, Dance Dance Revolution, Castlevania, Contra, Pro Evolution Soccer, Yu-Gi-Oh!, and Silent Hill.

Konami was also responsible for Frogger and Super Cobra, two very popular arcade games released in 1981.

Founded in 1969 as a jukebox rental and repair business in Osaka, Japan, Konami is a conjunction of the names Kagemasa Kozuki (current chairman and president), Yoshinobu Nakama, and Tatsuo Miyasako, partners acquired by Kozuki and the original founders of Konami Industry Co., Ltd in 1973. Konami also means “small waves.”
