The whole situation is really confusing.
Some people already ``adjust'' their names for a Western audience, and others don't. So, given the <name 1> <name 2> of a Japanese person, I don't know if <name 1> is the family name or given name. Some people already make the adjustment so that Westerners get it right, some don't.
I don't care either way -- I'd just prefer things be consistent so that when I recognize a Japanese name I can call them by the proper name faster :).
