This isn't worth a new thread so I'll stick it here since it is vaguely related. The new season of US TV series "Dexter" features a Japanese-American character called Yuki Amado who is played by Liza Lapira. According to IMDB, Lapira has Spanish, Filipino and Chinese ancestry. She will be the show's second Japanese American character: C.S. Lee already plays Vince Masuka. Lee himself was born in South Korea. With Korean actor James Kyson Lee playing Ando in "Heroes" and Jamie Chung playing Heaven in "Samurai Girl", there seems to be a mini-boom in Japanese characters on US TV series but few of them are played by actors with Japanese ancestry. This thread starts with an interview with Korean actor John Cho who will play the role of Sulu in the new Star Trek movie. James Kyson Lee was also up for the job but he has said elsewhere that he couldn't get time away from "Heroes". The actor playing Sylar in that show will play Spock in the film and the producers didn't want to lose two charcters at the same time.
You might think, with all this Korean acting talent, that it would just be easier to write a whole slew of Korean characters instead. However, I think maybe a Japanese character brings more associations for an American audience than a Korean character. Despite the large Korean-American population and the prominence of performers like Margaret Cho, I wonder whether the average Americans associates the population with much more than convenience stores. On the other hand, Japan brings to mind sushi, yakuza, salarymen, samurai just on a first pass.
