My name is Joel Castasus, and I am the owner of Shorin Martial Arts Bristol (Bristol Kodokan Matsubayashi Ryu).
​
My childhood in the Philippines was marked by adversity. Frail, underweight, and naturally introverted, I struggled with health issues and was often a target for bullies. My goal was simple: I wanted to become a superhero to overcome these challenges. To my young mind, martial arts was the only logical pathway to that strength.

My journey began in a local church hall. Despite my initial lack of coordination and athleticism, the welcoming nature of my first Sensei helped me persevere. I trained consistently until the difficulty became my new normal.

Over the years, I explored various styles—including Taekwondo, FMA, and Kickboxing—but it was Matsubayashi Ryu Karate (Shorin Ryu) that truly resonated with me. It offered the blend of simplicity, elegance, effectiveness, and culture I had been searching for.

My Mission As a dojo owner, I view it as both a privilege and a responsibility to introduce authentic Okinawan Karate to Bristol. I am passionate about sharing the art that transformed my life, hoping it will do the same for you.

Recent Achievement In November 2022, I travelled to Okinawa, Japan, to take my Sandan (3rd Dan) examination. I successfully passed under a panel of distinguished masters, including Yoshitaka Taira Sensei (10th Dan, WMKA President) and Toshimitsu Arakaki Sensei (10th Dan, WMKA Vice-President), renewing my license to teach authentic Okinawan Karate and Kobudo.

If you’re interested in training with us, please drop me a message. I read every inquiry myself and would be delighted to welcome you to the dojo.



Best wishes,
