Pancrase is a Japanese mixed martial arts promotion company based in Tokyo. It was founded in 1993 by professional wrestlers Masakatsu Funaki and Minoru Suzuki.
The name was based on pankration, a fighting sport in the Ancient Olympic Games. Suzuki and Funaki practiced catch wrestling. They based the promotion and its rules on professional wrestling. The promotion's champions were called "King of Pancrase".
The rules allowed closed-fisted punches, except to the head, and palm strikes to the head. From Wikipedia
