>it's a pretty random tossup between someone introducing themselves in family name first order or family name last order, even when speaking Japanese.
Same in Korea, except in Korean it's fairly rare to use "you" as a mode of address and everybody has a title or family term of some kind so you can often get away with outright forgetting/never learning somebody's actual given name. But if I fill out a form or something, even if I have to write my name in Hangul, the chances are really high that somebody will assume I've used the western system because I'm a foreigner and my FamilyName is actually my GivenName. There are just way too many variables that can creep in.
-Name in Hangul with western order
-Name in Hangul with East Asian order
-Name in roman letters with western order
-Name in roman letters with East Asian order
-something else (mangled, middle name acting as family name, etc)
The other day, a bank didn't let me transfer money from an account I had with them to an account I had at another bank because, they said, my name was written differently in Hangul than in the receiving bank account details. I said I didn't write my name in Hangul at any time while setting up either of the bank accounts, otherwise there wouldn't be a discrepancy. Didn't work. Also I know for a fact that bank systems here just cut off names that exceed character limits in both English and Korean.
I think the Korean government could fix this if it automatically issued a canonical hangul version of foreigners' names when they get ID cards here, but it will never happen, I think, for reasons that go far beyond immediate/large/practical concerns about updating systems etc.
I just grin and bear it while thinking of that patio11 post that often gets shared here, where he says he has broken many name systems in Japan just by putting his name into them.[1] That has been my exact experience in Korea.
Finally: regarding Abe's New Word Order, it seems like too much of a coincidence that the summer olympics are in Japan next year and the Olympic system, as far as I remember, capitalises family names.
edit: I may regret this, and it's kind of off-topic, but from what I understand about Abe, it makes a certain kind of sense that he does not want the Japanese to follow western naming orders in English anymore - he is an ultranationalist and ethnonationalist and a member of Nippon Kaigi[2].
