[1][2] Wado kai has numerous associated organizations and member clubs on different continents of the world.
[4] A Wadoryu Honbu (headquarters) was established in the Meiji University dojo in Tokyo, Japan in 1952.
[5] In 1964, the Japan Karatedo Federation (JKF) was established as a general organization for all karate styles.
The split occurred because the Wadokai board of directors and Hironori Ohtsuka had a difference in opinion about monetary expenditures and accessibility to the funds of the organization.
Ohtsuka felt it was within his rights to have full use of the Federation funds and one day made a withdrawal that drew the ire of the board of directors.
This matter was settled out of court and the terms of the settlement allowed him to keep the money but he had to resign from Wadokai and he also lost all rights to the name and logo of the organization.
[3] According to Ishizuka Akira, a veteran figure in the Japanese karate world, the term Wado Kai was in general use as early as the 1940s, but it was only in 1967 that the name was adopted formally.
With the formation of the Federation of All Japan Karatedo Organization (FAJKO, later changed to JKF) in the mid 60's, it was no longer correct to use this name so Wadokai came into formal use.
