I have never, ever supported dual citizenship for any American. Just don’t buy it.
You are in, or you are out. But that is me.
The Japanese would never accept her.
My bet is at 99% she and her greedy parents are lying. Did she renounce her US citizenship and formally give it up? Until I see evidence of this, she is lying.

Doesn’t the best player in baseball still refuse to speak English?
So she was a Japanese citizen, playing under a Japanese flag.
I am not sure what the story is.
People with dual citizenship make these decisions every day.
She can be a Jap if she wants. So what?
I’m confused. If her father is from Haiti and her mother is Japanese how did she get to be an American and how come her name is Osaka? That’s Japanese not Haitian.
People who need “dual citizenship” really disgust me. When America was great, immigrants were great too. They came here for freedom and opportunity. They gave up all allegiance to the country and royalty they came here to get away from. They didn’t beg for handouts. Now that America has gone full retarded third world, the immigrants are worthless panhandling beggers and they all need to be deported. They aren’t Americans and they will never be Americans.
Will she return sponsors’ money?
I’d guess that many, if not most, dual citizens are people, like my daughter, who was born while their parents were serving with the U.S. military or U.S. diplomatic service somewhere overseas.
Hate Trump person.
Whoever’s people you will fight to the death for, or choose canada. Good riddence.
No community? You are an island of selfishness taking up resouces, not what God put you here for.
Good. When Osaka loses, it won’t be as an American.
