Choosing a nationality is a huge responsibility. You should choose the country you truly love. No one who loves their country wants to see someone else come to their country just for the benefits.
Once you gain citizenship in that country you should assimilate to that country's culture. Multiculturalism isnt all its cracked up to be. Tolerance of race and creed and multi-ethnicity is a great thing. But become part of the country you intend to stay in. If Nyororin can do that, that's great and she appears happy. Probably a benefit to her community. Most people cannot necessarily assimilate to Japan.
