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.
Names are fun. I recently had dealings with a company that assumed in its employee roster that the last word entered in the name field was your last name (i.e. anything beyond the last space). One of my coworkers was from Spain and had a last name consisting of two words separated by a space. She was the very definition of a failure case for that system.
