Looking at Higashi's photo closer reveals to me that he is half-Japanese and most likely half-Hispanic. Could possibly be half caucasian, but I kind of doubt it.    Father must have been Japanese, and perhaps the mother was in the service in Japan? He wouldn't have both a Japanese first and last name otherwise. Japanese don't use middle names either.    All beside the point anyway, but just wanted to throw my observations in. One ugly little SOB any way you slice it.
