Kawika Yoneda

Kawika has been involved in sports and martial arts since the age of six. He started with Karate and Tae Kwon Do, then spent many years training Muay Thai, Boxing and Kickboxing. When his gym started adding Jiu Jitsu to their training, Kawika was not very excited about the change. He didn't see why anyone would take a fight to the ground if you could stay standing! He found himself skipping Jiu Jitsu class, and eventually ended up taking a break from martial arts for almost two years. This all changed in 2010 when a friend somehow convinced him to try out a Jiu Jitsu class again. Little did he know that the very reason he stopped training martial arts would soon become one of his greatest passions.

Weighing in at 240 pounds at the time, Kawika went to his first Jiu Jitsu class thinking he would be able to use his strength and size to his advantage, but he was in for a surprise. Not only did the instructor beat him, he did it with his eyes closed! By the time he left class that night Kawika had made up his mind that he was going to learn Jiu Jitsu.

Shortly after receiving his blue belt, Kawika started teaching some adult classes. Wanting to do a great job, but not having much experience in teaching or a broad knowledge of the art, he began spending a lot of time researching techniques online. That's when he came across the Mendes Brothers and Andre Galvao. Their style was intriguing and something he had never seen before. Kawika spent a great deal of time studying their matches and watching their techniques. A pivotal moment came after competing in the 2012 Pan American Championships in Irvine, California as a blue belt. Being surrounded by world class athletes , watching them live, and competing in such a big arena for the first time sparked something in him. He walked off the mats and knew this is what he wanted to do for the rest of his life. After a lot of prayer and consulting with his girlfriend, Jamie, they made the decision to follow this dream and started saving and planning their move to California for Kawika to train Jiu Jitsu full time.

Kawika and Jamie were married in November of 2013, then in January 2014, they packed everything they could fit into 4 suitcases and boarded a plane to California. This was a big leap of faith to leave everything that was familiar and the life they had in Hawai'i for a great unknown, and a place they had never been. 

Kawika chose to train at the Art of Jiu Jitsu Academy (ATOS Costa Mesa) under Guilherme and Rafael Mendes. He chose the Mendes Bros not just because they are among the best in the world but because of their faith in God and Jesus Christ. Over the next 2 years, Kawika had the opportunity to learn, train, compete and grow as an athlete. Even before moving to the mainland, Kawika knew that California would not be a permanent thing for them, because part of his dream was to come back home to Hilo and bring what he had learned with him. He wanted to build a strong team from Hawai'i and to bring opportunity to those in his hometown with similar goals. 

These dreams are becoming a reality through opening Roma JJA as the first ATOS affiliate in the State of Hawai'i. This has been a very humbling experience and also a huge honor. Kawika has a great respect for the ATOS Association and looks up to Andre Galvao and the Mendes Bros not only for what they have built, but the example that they are through their Jiu Jitsu and also the strong foundation they have in their faith. Kawika received his black belt from the Mendes Bros in July of 2017.

"I want to extend my deep love and appreciation to everyone who has helped me along this journey; to my beautiful wife, my family and friends for their never ending love and support, and above all else to my Lord and Savior Jesus Christ. As long as we put God first, there is nothing we can't do."
