The Japan Karate-Do Federation Goju-Kai (JKF Goju-Kai) is one of the major organizations dedicated to the practice and promotion of Goju-Ryu Karate-Do, a traditional Okinawan style known for its blend of hard (go) and soft (ju) techniques.

As part of the Japan Karate Federation (JKF), the Goju-Kai follows a structured curriculum that includes foundational kihon (basics), kata (forms), and kumite (sparring), all rooted in the principles of discipline, respect, and personal development. The organization also plays a key role in the global standardization and spread of Goju-Ryu Karate-Do, offering instruction, seminars, and official rankings to practitioners worldwide.

Through its strong traditional base and modern organizational structure, the JKF Goju-Kai continues to cultivate skilled martial artists while honoring the legacy of its Okinawan origins.
