Founded in 2007, the GOJU RYU PORTAL began as a private resource for an elite group of senior instructors dedicated to preserving the traditional teachings of Japanese Goju Ryu karate. It was created at the direct request of the legendary Grand Master Ohtsuka Tadahiko, O-Hanshi—mentor to our Founder—to share and protect the true essence of this time-honoured martial art.

What started as an exclusive platform quickly grew in reputation. By 2020, interest from around the world surged as more instructors and dedicated students sought authentic, credible knowledge in a sea of misinformation. In response, the Portal was opened to the global karate community and has since become a trusted destination for serious martial artists everywhere. Today, the GOJU RYU PORTAL proudly serves thousands of members across more than 160 countries, united by a shared passion for traditional Goju Ryu karate-do.

Every piece of content within the GOJU RYU PORTAL is meticulously curated and deeply rooted in the teachings of legitimate master instructors with decades of hands-on experience. These Senior Master Instructors, certified in Japan and Australia, hold Bubishi Master ranks and senior black belt gradings, ensuring you receive only the most accurate and time-tested knowledge.

Operated as a not-for-profit initiative, the Portal remains free from commercial bias. Our mission is clear: to provide high-quality, authentic and credible Goju Ryu information and knowledge to practitioners worldwide. With over 140 years of combined expertise behind our team, we are committed to helping you deepen your understanding and sharpen your skills—wherever you are on your martial arts journey.
