Hi Its a great article but no matter what you will always get a different opinion from Iwama deshi and Hombu deshi. Its well known that most of O'Sensei's time was spent in Iwama teaching and developing Aikido and he did travel lot to his other dojos. Morihiro Saito is famous for saying that O'sensei really only taught in Iwama but demonstrated at the Hombu. im not saying this is def how it was even as an Iwama deshi. But one of the big differences in the 2 are that in Iwama the teacher was O'Sensei or Saito in the Hombu it was Mostly his son or people like Tohei who both made MASSIVE changes to the founders art that he was teaching in Iwama. Im not saying ALL these changes where bad, but these changes happened. I think its better if some of the sempai here speak of there understanding, especially the ones who spent a long time in Japan.
It was nearly the same in Iwama. Saito was perhaps the one with the most amount of time, but even then, it wasn't extensive. There were only two training periods per day.
Morihei's daily schedule in Iwama in those years:
7:00-9:00 A.M.: Aikido training followed by a simple breakfast.
4:00P.M.-6:00P.M. Aikido training.
Now, that might seem like a lot but consider that Ueshiba split his time between Iwama and Tokyo. Not only that, but he traveled extensively and entertained guests regularly.
