Seagal Sensei studied under Koichi Tohei (another for Orange County, California) in the summer of 1974 before traveling to Japan shortly thereafter.
If he went to japan for the first time in 1974, how could he have possibly met or seen Ueshiba M. alive? I'm not saying the article isn't genuine...I have some questions about the accuracy of the impressions it gives. Some of those impressions may be unintentional, or were added during the transcription of the interview, or by the writer. But dates don't lie.
