There was a Yasuo Fukuda who used to teach at the old Washington Judo Club on Florida Ave. NE in DC in the early 60s while working on a masters degree at GW University. Not somebody who was going to take Osao Okano or anything like that but had the signature of all judoka from Keo i.e. 100% ambidextrous i.e. anything at all he could do to one side he could do equally well to the other and was fun to watch for that reason.
Same person to your knowledge?
