Creation of Kodokan Judo by Dr. Kano
unified multiple schools of jujutsu and, for the first and only time,
created all-Japan martial art. Judo remains largely unified, thanks
to Kodokan and IJF, but in the course of its history a few
independent Judo styles branched out under different circumstances
and they still growing under their own rules.
The reasons for branching ware of two
sorts: (1) political and/or geographical separation from Kodokan
(SAMBO and Brazilian jiu-jitsu) and (2) Judo sport competitions
(Olympic Judo and Kosen Judo).
When each of those styles in the first
group (SAMBO and BJJ) seen nowadays as independent martial art and/or
combat sport on its own rights and often accepting their relation to
Judo with many reservations and just as a personal background of the
style founder, they are truly a part of the global Judo development.
By rejecting Kodokan link SAMBO and BJJ preserving their organizational structure and
business model. But the political interests of their federations have
nothing to do with the styles themselves.
The second group (Olympic and Kosen
Judo) on the opposite claiming to be the “true Judo” that are
loyal to Kodokan haritage. That even when Olympic Judo is governed by
IJF (International Judo Federation; Kodokan has significant
influence, but not authority over IJF) as a combat sport and not a
martial art, and when Kosen Judo was branched out by Dr. Kano himself
as Japan-only combat sport style when he started to introduce Judo to
the rest of the World.
Dr. Kano created Judo not from the thin
air, but on the solid foundation of old Japanese jujutsu. When on
July 24, 1905 majority of leading jujutsu school representatives
agreed upon accepting Kodokan as their “umbrella” organization
their schools overnight became “judo” schools. One of the
conditions of this agreement was preservation of traditional
technique of each school in the kata form. In fact, it took 50 more
years for outside observers to stop calling Judo “jujutsu”. But a
few of those old schools managed to survive on their own and a few
more new "old” jujutsu schools ware established over time. Within
spirit of July 24 agreement I see those schools as branches of
