In 1955, Masatoshi Nakayama, a student of Mr. Funakoshi since 1931, was appointed chief instructor of the JKA and directed the technical development of the organization. Mr. Nakayama introduced karate as a sport, along scientific lines, and is largely responsible for the popularity and propagation of karate internationally. In 1987, Mr. Nakayama expired at the age of 74.
The JKA placed strong emphasis on the character building aspects of karate training. Sportsmanship and respect for one's opponent are cardinal principles. To keep pace with the growth and development of its students, the JKA has a technical committee who is responsible for continuing research and revising karate techniques.
Mr. Teruyuki
Okazaki, another disciple of Mr. Funakoshi, developed the International
Shotokan Karate Federation (ISKF), a direct affiliate of the JKA. The ISKF
has over 50,000 members with more than 200 clubs in 28 countries. As the
Chairman and Chief Instructor of the ISKF, Mr. Okasaki travels extensively
to conduct examinations and clinics across the globe. The ISKF has a rigorous
instructor training program for individuals with the desire and aptitude
for teaching. As part of this curriculum, trainees are required to submit
43 essays on subjects ranging from kinesology to the philosophy and history
of karate. Upon graduation, trainees are licensed by the ISKF/JKA and have
worldwide recognition as instructors, examiners, and tournament officials.
