BTW, I find it amusing when I hear Western teachers say in videos: "Hi, I am X sensei and I am the head of this dojo". A japanese will not refer to himself as sensei, as it is a honorific title used by others. Just as a British or American wouldn't call himself "Sir".
(this is probably way off topic, btw)
That's true, Ueshiba used to introduce himself by saying "I am Ueshiba" (in Japanese) - no honorifics. The same when signing a letter or similar document - no honorifics.
