Japanese game publishing and development giant, founded in March 1969 by Kagemasa Kozuki as a jukebox rental/repair business. The company was officially established under the name Konami Industry Co., Ltd. in March 1973. Made famous in the old days for the Teenage Mutant Ninja Turtles, Contra coin-ops series, and Castlevania, Konami expanded its brands over the years with titles like Metal Gear Solid, NBA In the Zone, NHL Blades of Steel and Silent Hill, as well as a large number of rhythm games like Dance Dance Revolution.

Since then, it has successfully grown with increased product franchises and continues to expand its lineup for both the home and coin operated markets. In 1998, Konami became a $700 million dollar publicly traded company in Tokyo with 2000 employees over the world. It has offices in North and South America, Europe and Asia as well as Japan.

Konami first opened a North American office in Los Angeles in 1982. In 1984, the U.S. Headquarters were moved to Chicago so that it could better serve both the home market as well as the growing coin operated business. Konami of America later moved to Silicon Valley and finally settled in Redwood Shores in Northern California.

In 2004, Konami's subsidiaries included KCEO (Konami Computer Entertainment Osaka) and its internal soccer development team Major A, KCEK (Konami Computer Entertainment Kobe), KCE Tokyo, and the Konami Computer Entertainment School in Tokyo. It also invested in companies like Hudson and Takara and operates health clubs and arcade machines.

The company abandoned its classic orange logo in 2003 and replaced it with the text-only version seen above.

On April 1, 2005, Konami will merge its subsidiary development studios. It will also merge Konami with Konami Online to concentrate on the ever-growing online gaming business.
