Zach Kaina Biography

Zach Kaina was born on May 23, 2002, in Oahu, Hawaii, USA, where he spent his early childhood, prior to his move to California at the age of 10.

The introduction to martial arts came by way of karate at the age of 5, a short-lived experience as Kaina did not find the striking-based combat style appealing. Being from Hawaii, Zach’s family was well aware of BJ Penn – a famous Hawaiian, former two-weight class champion of the UFC, and the first American athlete to win an IBJJF World title in the adult black belt division. So, when little Kaina fell out of interest in karate, his mom was quick to add him to a local jiu-jitsu school.

As a 6-year-old, Zach Kaina began his grappling tuition under the guidance of Mike and Chris Onzuka of team O2 (and later adding Kyle Nitahara), receiving all belts up to orange in Hawaii.

Already fully embedded in jiu-jitsu culture, by the age of 10, Zach moved to Costa Mesa, California (along with his family) to train at the Art Of Jiu-Jitsu Academy (AOJ) under the Believe & Achieve kids program, one of the sport’s most accomplished curriculums.

Zach Kaina arrived at AOJ as an orange belt, quickly becoming one of coach Guilherme Mendes’ top performers. Kaina went from the orange belt all the way to a professional level with AOJ, receiving his black belt on December 09, 2023, from the hands of Guilherme Mendes.
