Ahh so cheap houses are only for citizens?

EDIT: So after a quick search: there are no residency requirements for any foreigner to buy a house or land in Japan, you can do it on a tourist visa.

You can be a resident without citizenship. You just need a visa, which requires some kind of reason to be in Japan other than tourism. E.g. work, school, etc. I’m sure there’s other caveats though. If this is being sold by the government, then they would probably want to ensure that the occupant will live in it long term and not leave it abandoned after their visa expires.
