The fact that Japanese culture was originally seeded by and proceeded to be heavily and thoroughly influenced by Chinese culture is a vacuous argument in favor of the idea that Ueshiba's martial arts were influenced by Chinese martial arts. You may as well say that Aikido is exactly the same thing as Tai chi because most people have two arms and two legs.
It had to be felt, right? So who did Ueshiba feel it from? That's where this story has to start.
Well, I'm fairly sure that most Aikido students feel that they have been heavily and thoroughly influenced by Morihei Ueshiba, even though most of them have never felt them, even though the actual contact is, in many cases, three or four generations in the past.
