Yeah, I heard about the "Gaijin" phenomenon that you can't really become Japanese and you will(probably) always be a foreigner. But also heard that they often say it without any bad intentions. As I think about this, we tend to say it too during casual conversations in my country. "Yes, he is a foreigner, he is from xy", "the foreigner girl?" etc. without any bad intentions. That full citizenship law is rare though, as far as I know in most countries you can take up the nationality. Hm, different laws, different culture.

Anyways, what about crimes? Is it safe in the evenings? Like walking alone or going out at night, etc.
