The Okinawan roots had been left far behind and, in the opinion of at least some of the JKA seniors, Okinawan karate was not perceived to contain anything of value. They were confident that the original Okinawan methods introduced by Funakoshi had been considerably improved upon by his Japanese followers, and there was nothing to be gained by investigating Okinawan karate systems. Masatomo Takagi, with a confidence verging on arrogance, observed in 1960 that "We (the JKA) studied Okinawan karate, but found that it lacked.....theory."
And so it comes full circle with TKD, with some fairly high ranking people saying the same thing about TKD, its patterns applications not listed in the encys and its roots in Shotokan.
Funny how things tend to repeat themselves eh!
