We have a lot of Korean tourists in Tokyo (you can spot them usually by their style of clothes even before they speak); I've got to say, I'm impressed that most I encounter are humans: Wandering the nightlife spots, restaurants, cultural centers. Even the twenty-something party-types might be a little loud but certainly respectful for the most part: And also, for the most part, thin and human. I started making assumptions about how all Koreans were shitlord-thin (especially given the legendary stories of full-length mirrors in all schools, people always checking their hair/body in mirrors, so much plastic surgery, etc); then for a few business engagements I went to offices in Akihabara (the "otaku district"), and... yep... that's where all the fatty Koreans congregate.
