This was the first PlayStation game to exceed 1 million copies sold.
The developers were originally going to title the game as "Rave War". But the team abandoned that idea and replaced it with the ancient Japanese word known as "Tekken" (meaning "Iron Fist").
The player can listen to all of Tekken's music with a CD Player.
In Jack's epilogue, the machine connected to Jack is named "System 11", which is the name of the arcade hardware used by Tekken [1994] and Tekken 2 [1995].
