Black Belt Rank Testing and Certification

The NJK tests and certifies Danzan Ryu Jujutsu Black Belt ranks. High standards of skill, knowledge, proficiency and ethical conduct are required for an organizationally recognized NJK Danzan Ryu Jujutsu Black Belt rank.


The NJK sponsors many clinics during the year. In-depth classes encourage the exchange of information between NJK schools and their students and cover the broad spectrum of techniques in the Danzan Ryu system. Black Belt and Brown Belt workouts are focused on the upper techniques of the system in preparation of advanced testing.  Additionally, focus is placed on emphasizing ‘the little things’ that are at the foundation of our system. All Dojo Workouts are open to all students and cover the areas of Danzan Ryu such as Yawara, Nage Te, Shime Te, Oku Te, self-defense applications, as well as other composite arts.

NJK Gasshuku

Gasshuku is our annual training event and banquet.  NJK schools, students, special guests and instructors gather for intensive study and fellowship. Gasshuku is a great opportunity to meet and study with the NJK Professor, school heads, and both association and guest instructors.

Restoration Therapy / Healing Arts Clinics

Danzan Ryu Jujutsu founder, Professor Okazaki was well known as a healer and therapist. His Restoration Therapy treatment is the core to the Danzan Ryu Seifukujitsu system.  Clinics are open to all NJK schools and their students who desire to learn and gain proficiency in the healing arts. Certification in Basic Restoration Therapy, Kappo (resuscitation/revival arts) and basic first aid is required for instructors grading in the association (Nidan and above).
