In elementary school Akeomi Nitta loved baseball; during junior high he chose not to pursue sports, instead concentrating on other activities.

Soon after he met his teacher, Mr. Katsuyama, and became a pupil of S.V.G., a kickboxing gym, he won the championship of Shin-karate absolute class by knocking out all his opponents.

He knocked out another future welterweight champion, of the All Japan Kickboxing Federation, Tatsuya Suzuki, and won 12 straight matches from April 1994 to September 1998.

Two months later, he beat an Italian kickboxer and won the title of WKA World Thai Boxing Super Welterweight champion in Milan, Italy.

In 2005 he defeated Ash-Ra, Takehiro Murahama and Koutetsu Boku while losing to Takayuki Kohiruimaki and Ian James Schaffa.
