I don't remember what countries, but I know there are North Korean restaurants in other countries. With actual North Korean women working there, having to live on premises and be vetted for political loyalty while essentially being under surveillance.
Looked it up and Wikipedia was saying they're all essentially fronts for laundering foreign currency to send back home. Other sites have been saying that these restaurants have been closing since the pandemic.
Not just Japan. When they need language teachers and translators, they just dock their subs close to the beach of the country, and kidnap anyone they found there.
This sub is "Today I Learned", not "Today You Learned." OP just learned about it and wanted to discuss with other people. Seems reasonable.
And, indeed, though I knew most of this, I've still found some of the discussion interesting. What, then, is your problem? No one is forcing you to visit the thread at all.
