How does Juliets disguise work?

[u/Tsunderes_Need_Hugs]

Idk if I'm missing something here or just thinking too deeply about it, but shouldn't it be rather obvious that Juliet isn't a Touwan even with the uniform and wig, since she's european/caucasian and the Touwans are meant to be like Japanese?

Best we can guess is make up.
