Mario Sergio Yokoyama, Head Instructor (Australia)

Internationally regarded as both a teacher and competitor in both Brazilian Jiu Jitsu and Mixed Martial Arts, Professor Mario Sergio Yokoyama is known for his technical prowess, attention to detail and passion for martial arts.


Growing up training both Judo and Brazilian Jiu Jitsu in his hometown of Sao Paulo, Brazil, Mario’s life has revolved around martial arts. Both a competitor and teacher of the highest level, Mario has studied under Roberto Lage and Rickson Gracie, before earning with his black belt in Brazilian Jiu Jitsu under Ryan Gracie.


At the age of 16, Mario moved to Japan to continue his martial arts training. During his nine years in Japan, he became renowned for his training methods and technical knowledge and began teaching. Mario’s many achievements in Japan include teaching Brazilian Jiu Jitsu at the Police Academy in Nagoya, Japan.


After spending time between Japan and Brazil, Mario moved to Australia in 2006, where he would go on to establish the Gracie Oceania Academy. The school had humble beginnings, with the first students training in Mario’s backyard. A short time later, Mario rented a small space at a boxing club to accommodate the increasing number of students wanting to train with him.


In 2010, Mario established his first full-time academy in Marrickville, which quickly grew to become one of the most formidable BJJ teams on the competition scene — despite being one of the smallest clubs in Sydney. In 2014, the club was re-named Mario Yokoyama Brazilian Jiu Jitsu (myBJJ) after its founder and Head Professor.


As the club continued to grow exponentially, Mario moved the club to a bigger space in Camperdown in 2015. With more than 400 sqm in floor space – including two separate training mat areas to allow for two classes to run simultaneously – the myBJJ school in Camperdown is now the headquarters of the myBJJ Academy.


With campuses and affiliated clubs across Australia, New Zealand and Japan, myBJJ is now one of the most respected names in Brazilian Jiu Jitsu in Australiasia.
