Most importantly, this interview is yet another account that states that O Sensei personally taught Aikido, on the mat as it were. He was not, therefore, retired after 1941.
You mean this part?
Did O-Sensei himself teach?
Yes, he also taught. The dojo used to be downstairs. There was a room next to the dojo and O-Sensei used to sit there and watch us practice. He sometimes came out of the room and instructed us
Anyway, it's not a yes/no thing - it concerns how much he taught, what he taught, and how he taught it.
