Koji Shibamoto Biography

Koji Shibamoto was born on August 23, 1980 in the Aichi Prefecture, Japan. He started practicing martial arts from a young age, being Judo his main sporting activity, where he became a Japan representative at an international level and one of Tokai University’s most prominent judo standouts. After graduating from university in Physical Education, Shibamoto spent some time working at a sports club and lost some of the focus in Judo. He decided he needed a new challenge in life, and in 2004 started looking for jiu jitsu academies where he could get the best instruction.

After seeing an instructional DVD by Mitsuyoshi Hayakawa, teaching his jiu jitsu techniques, Koji Shibamoto was truly impressed and chose to learn under Hayakawa, signing up for the Tri-Force gym. One year later, Shibamoto was already proving that he was a gifted athlete by winning the All Japan tournament in the blue belt division.

With time, Koji Shibamoto decided that jiu jitsu was his true calling and quit work to dedicate his full attention to jiu jitsu. His perseverance and work ethics paid off in a big way when, in 2010 Shibamoto won the World Jiu Jitsu Championship in the brown belt division, receiving shortly after the tournament (on the 19th of June, 2010) his well deserved black belt by the hands of his instructor Mitsuyoshi Hayakawa, an achievement he accomplished with little over 5 and ½ years of BJJ training.

  • I trained with Shimbamoto when in Tokyo on holiday and was very impressed. He treated me just like one of his other students and after two training sessions I was sad to leave. I still remember him stretching for the next class and giving me a big smile and wave goodbye. I hope to train under him again for a full week at the end of this year.

  • shibamoto sensei is a super badass, and a great instructor
