Last month, Korean pop group Sistar transformed into "Sailor Star" for a commercial to promote online Korean shopping site 11st. Some aren't happy about that!
Online in neighbouring Japan, online commenters wondered if the online shopping site got permission to use the Sailor Moon imagery.
"I thought [Korea] hated Japan?" wrote one commenter on 2ch, Japan's largest forum. "Stop stealing everything possible from Japanese culture," added another. "Knock it off!" Oh boy.
Well, the commercial is a lot of fun.
