What Makes Us Different?

We are the only certified Japanese Shotokan Karate school in the Fontana area and the only school with a father-son black belt instructor team teaching every class.

Our students are more than just numbers. We cap class sizes at 25 students to maintain quality and build a focused, respectful training atmosphere.

Testimonials

Members Feedback & Reviews

"Shihan Joseph runs a fabulous Dojo. He truly cares about his students. Both of my sons have learned a lot over the past three years training at Claycomb."

Brianna ZapataParent

"Amazing family-owned business with skilled, patient and passionate teachers! My son has been attending for a few months, and he loves it! He is not only developing his physical skills, but his self-confidence, ability to self-regulate and overall well-being have improved too. We are very happy with our experiences with the dojo!"

Ryan RayParent

"Claycomb is the best decision I made for my daughter she has gotten out of her comfort zone and has been a little more confident. Everyone is so friendly, it’s very nice inside and cool. We get to watch our kids practice on the screen while we sit down in the waiting area. The owner and the sanseis are very welcoming to everyone and challenge the kids."

RosemaryParent

"We’ve been with Claycomb for almost two years. It’s been amazing to watch the growth in my son. He has so much more confidence and loves coming to karate each week. Thank you CKA!"

Jocelyn FrancisParent

"I love how Claycomb teaches both traditional karate as well as kickboxing techniques. The variety keeps classes interesting, and gives me the opportunity to use different skill sets. Shihan Joseph is very detail-oriented, and does a great job with teaching me how to improve my form to become a more effective martial artist."
