About Shorin Martial Arts Bristol
​
My name is Joel Castasus, founder and owner of Shorin Martial Arts Bristol (Bristol Kodokan Matsubayashi Ryu).
​
My journey into martial arts began not from strength—but from struggle.
Growing up in the Philippines, I was frail, underweight, and naturally introverted. I faced health challenges and was often the target of bullying.
Like many young people searching for confidence and strength, I dreamed of becoming something more—someone stronger. To me, martial arts became that path.
​
I started training in a small church hall, lacking coordination and athletic ability. But through the guidance and encouragement of my first Sensei, I persevered. Over time, what once felt difficult became part of who I am.
​
I explored various martial arts, including Taekwondo, Filipino Martial Arts (FMA), and Kickboxing. However, it was Okinawan Martial Arts, Matsubayashi Ryu Karate (Shorin Ryu) that truly resonated with me. Its balance of simplicity, elegance, effectiveness, and deep cultural roots set it apart—it wasn’t just training; it was a way of life.

​
Our Mission
​
At Shorin Martial Arts Bristol, I see teaching as both a privilege and a responsibility. My mission is to bring authentic Okinawan Karate and Kobudo to Bristol, preserving its traditions while making it accessible to everyone within a modern lifestyle.
​
This is more than self-defence—it’s about building confidence, discipline, resilience, and character.

​
Authentic Lineage & Achievement
​
In November 2022, I travelled to Okinawa, Japan—the birthplace of Karate—to undertake my Sandan (3rd Dan) examination. I successfully passed under a panel of distinguished masters, renewing my licence to teach authentic Okinawan Karate and Kobudo.
