I was out fishing, and it was good
Okamoto was a student of Horikawa Kodo for many years. Okamoto was the first of Kodo's students to receive 7th dan and shihan. Upon Kodo Sensei's death, Okamoto decided to open his own school, primarily because he had moved to Tokyo and the distance to Hokkaido was great.
Okamoto Sensei's primary focus is on high level balance breaking and locking skills. While that is his main goal, his jujutsu technique is stellar, but seldom seen by the public.
If you have more questions about Sensei or the Roppokai, please free to contact me.
Thanks for writing.
PS Thanks for the kind words Don, How is the shoulder ?
