One teacher says that in his later years he was in tokyo teaching quite often. Being there training Alan Ruddock says he saw him about two hundred times. He went to many of his lessons.
Ruddock also says "It was obvious to the intelligent observer that what O-Sensei was doing did not fit in with 'normal' practice."
So normal practice at Hombu in the late 60s was not O Sensei's aikido.
