From the BBC World Service: Tech giant Amazon says it's blocked more than 1,800 North Koreans from trying to join the company in the past two years.

Plus, "oshikatsu" is a Japanese term referring to fervent fan subcultures surrounding things like sports teams, pop stars, or anime — and it's helped pull Japanese retail sales out of a slump.
