Will an unaccredited college diploma count?

Before you jump down my throat, I was really stupid and desperate and didn’t do my due diligence. But I have a degree from a college that is unaccredited (not even national accreditation).

I looked through the subreddit, and there was discussion of regional vs national accreditation, though there isn’t a clear answer whether or not Japanese immigration would accept a nationally-accredited degree.

Questions:

1. If I submit an apostilled diploma from an unaccredited college, is that considered immigration fraud? I don’t speak Japanese well, but I attempted to talk to some lawyers here and they literally have no idea what accreditation is, let alone the difference between national and regional.
2. I don’t mind doing a lowly-paid English job – do they care if my diploma is unaccredited or not?

Thank you so much. And yes, I am kicking myself in the butt for this, but what’s done is done. For anyone considering a college in the future … make sure you check its accreditation status unless you want a lifetime of stress.
