The 9 Bujinkan Ryu-ha and its importance
When Hatsumi Sōke taught the schools during the 80’s up til his retirement in 2020. I never heard him say that knowing the techniques in the 9 Bujinkan Ryu-ha was important. We train the techniques from the Ryu-ha as if they belonged to one system, Bujinkan Dojo Budo Taijutsu.
