Holy shit, I haven’t thought about this in years! I remember back in 2008 I had a copy of Stepmania on a flash drive and played it on school computers during class.

I had the exact same thought when I read the premise. One of my favorite indie games of all time.

The second sentence of the Wikipedia article literally says about 2/3 were American citizens.

The section on ‘Exclusion, removal, and detention’ says “[s]omewhere between 110,000 and 120,000 people of Japanese ancestry were subject to this mass exclusion program, of whom about 80,000 Nisei (second generation) and Sansei (third generation) were U.S. citizens.”

So yes, second and third generation Japanese Americans, natural born citizens, were held in American concentration camps.

It’s there purposely as a part of the satire. It’s meant to be a critique of the use of passive voice in news headlines.
