One of the interesting things Shirata did for us in my opinion was to free us in a way from the obligation of tatemae -- to take what he gave and to wither or thrive on the outside so to speak.
Shirata Sensei is one of the few students of O Sensei from the very early Kobukan years who did not create their own organizations. After the war, when he returned to aikido after a long interval, he publicly supported Kisshomaru Ueshiba. In fact, I knew Shirata Sensei as a member of the Superior Council of the IAF, which Kisshomaru created. Like a few other postwar shihans he supported the Ueshiba family as a way of preserving and developing aikido.
In my opinion this public support was a tatemae
and was the public face of the honne
: his own private study of the inheritance he received from O Sensei at the Kobukan. Nearly all the shihans I know well exhibit this division to some degree.
