It could be per-language, i.e. use family-given when speaking Japanese or given-family when speaking English. That's more what I'm getting at.
This would also (I'd propose) hold true for non-Japanese names; if family-given is conventional when speaking Japanese, and my English name is John Johnson, it'd only be fair for my Japanese name to be ordered as Johnson John.
