高田延彦
After an August 2003 training accident while training with Kenzo Suzuki at World Japan's dojo, Okada suffered an acute subdural hematoma and entered a coma from which he never recovered. Okada died on August 8, 2003. Okada's August 13 wake was attended by Masaaki Satake, Nobuhiko Takada, Kazushi Sakuraba and World Japan Management Director Katsuji Nagashima. A moment of silence was held in PRIDE Grand Prix 2003 in his honor.
