Aikido of Hilo just announced the sad news of the passing of Robert Aoyagi Sensei on their Facebook page:
Robert H. Aoyagi Shihan, Chief Instructor of Aikido of Honolulu, passed away on November 16, 2010. He had just celebrated his 90th birthday and over 50 years in Aikido. Condolences go out to his family, especially to his devoted wife, Dora.
I met Aoyagi Sensei once in 1979 while accompanying Saito Sensei for a seminar. He was a fine person, excellent leader, and devoted aikidoka. R.I.P. – Stanley Pranin
