 The conclusion of both of these surveys was that it would be inappropriate to introduce bujutsu (Japanese martial arts in general) into the school curriculum, in anything other than a spiritual way (the 1896 survey suggested that boys over 16 could study bujutsu).This led to a number of people, notably Ozawa Unosuke and Nakajima Kenzo, to try to develop a gymnastics adaptation of bujutsu.This was met with some criticism, and it was noted that the techniques were ineffective and did not take into account the blade or the direction of travel.
