Let's settle this for once and all. He is not from Canada. I repeat, he is not from Canada.
you are missing my point. A lot of people believed wikipedia article that stated he was born in Prince Rupert, Canada with a source from bullshit Dynasty Warrior Gundam game.
Well, he is not, and I am here to correct that false statement.
It was never from Dynasty Warriors anon, that just repeated it. It was from the movies that people got that - which the article you just linked flat out says, so I'm not sure why you're trying to undersell it by acting like Dynasty Warriors was the only source to ever say this. And in the novels he's Mexican if I recall. So even Yoshikazu saying he's from Sanin in Tokyo isn't really definitive because it depends which version of him they're talking about.
In the TV series they left America and are already trekking across the Pacific Ocean when they first meet Ramba Ral, and an episode or two later they stop on an island and Amuro flies home.
It's pretty clear they're in Asia by this time, just not where in Asia exactly.
