The Legacy of Mejiro Kickboxing

Our Muay Thai Kickboxing style originated from the Mejiro Gym in Japan, founded by Sensei Kurosaki, a martial artist known for blending the power of Kyokushin Karate with authentic Thai striking techniques. The style was proven in real competition, producing elite fighters like Toshio Fujiwara, the first non-Thai to win a national Muay Thai title in Bangkok.

In 1978, Jan Plas brought Mejiro Kickboxing to the Netherlands, where Rob Kaman — a nine-time world champion — became one of the most respected Muay Thai fighters in history. Under Rob Kaman’s direct mentorship, Professor Sam Marcellini became the first certified instructor in the United States, continuing the Mejiro legacy right here in Riverside.
