Giant Ochiai

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.

In 2000, after Seidokaikan mainstay Masaaki Satake tried his luck in PRIDE Fighting Championships, Okada followed him in order to do his own debut. He gained the ring name of "Giant Ochiai", sporting shades and a large afro wig over his actual afro hair during his entrances, which drew popularity among the fans. The origin of the name would be found in his large height and weight and his mother's maiden name, Ochiai.

Also in 2000, Ochiai debuted in professional wrestling, working sporadically in the stiff style Battlarts organizations. He joined Riki Choshu's World Japan promotion for proper training.

As a student, Okada won the All Japan Industrial High School Judo League Championship four times. After graduating from college, he would went to train at the Seidokaikan Tokyo Bom-Ba-Ye dojo with Naoyuki Taira. He also joined the amateur division of Shooto, placing second in its All Japan Amateur Shooto Championship in 1998 and 1999.

Takayuki Okada (May 8, 1973 – August 8, 2003), more widely known as Giant Ochiai, was a Japanese professional wrestler and mixed martial artist. Okada's MMA record was 3-3-2 (Win-Loss-Draw).
