English should adopt the French convention of capitalizing the family (last) name. For example, this would make it ABE Shinzo, which would remove ambiguity. When encountering East (thanks for the reminder) Asian (or Hungarian, for that matter) names in emails for example, I'm usually worried about if their "last" name in the directory is their given name and what they should be addressed by or their actual last name.
It probably doesn't matter too much, but this is a lossy conversion. For example "Fred McIntosh" -> "MCINTOSH Fred". So the capitalization of the "I" is lost.
