Konami is a Japanese entertainment and gambling conglomerate holder company located in Ginza, Chūō, Tokyo. It was founded on March 21, 1969, by Kagemasa Kōzuki in Osaka, stating him with his two co-founders' surnames of the company's name: Kagemasa Kozuki, Yoshinobu Nakama and Tatsuo Miyasako.
This logo was adopted in March 1981.
In August 1986, Konami introduced a new logo. The "bacon strips" were introduced (which would be used until 2003), and the wordmark on the bottom was given a new font (Univers Bold) and became all-uppercase, italicized, and colored gray; sometimes, the logo was placed in a boxed frame.
In October 1998, the Konami wordmark was made black and straightened upright. Like the last logo, a boxed frame is sometimes put around the logo. The wordmark is still being used on the card backs for the Yu-Gi-Oh! Trading Card Game.
In April 2003, Konami introduced a new logo, in which the Konami "bacon strips" were abandoned. This logo consists of a knife-shaped banner with the word "KONAMI" in it. This logo is still used by Konami Sports Club.
In 2013, the knife-shaped banner was removed, leaving only the wordmark from the previous logo.
