In the Edo period many of the famous budoka mastered their study in about the same period of time but these men were not beginners either. They were usually highly trained professional warriors. The founder of Shindo Yoshin ryu was highly licensed in 5 different traditions by the time he was 32 years old, holding terminal licenses in Tenjin Shinyo ryu and Jikishinkage ryu.
How often would a trainee attend training in those days? Was menkyo kaiden in 5-7 years in part a result of the fact that student and instructor would meet for a couple of hours a session, many times a week?
