Look up "Professor Toru Tanaka" on ImdB sometime. His real name is Charlie Kalani, and was an American (Hawaiian), not Japanese. He served honorably in the US Army and had some movie roles, most notably with Arnold Schwarzenegger. Another wrestling "heel" who was a good guy in real life.
I remember Professor Tanaka, The Iron Sheik, The Assassin, Chief Strongbow, the Briscos, and the Mexican who proved a big man can fly like a bird, Mil Mascaras. I was a fan when it was great theatre, not today’s homoerotic bs.
