They don't have any Japanese members. Your probably thinking of Keno Eto but he wan around in the 60s/70s. In the 20s one of the highest guys up were Jake Guzik who was Polish. Succeeding his role was Gus Alex who was Greek. Then of course there was Murray Humphrey's who was Welsh and probably the highest ranking non-Italian member in Chicago. But none of them were ever made and there was always an Italian higher up. For example when Murray Humphrey's and Gus Alex were around, Ricca and Accardo were higher up. Same with Jake Guzik and Capone. Today there aren't any non-Italians as high up as they were but there are still some Irish, Greeks, Polish, ect associated with them.
