This amazing man, Masi Oka was not well-known in Japan till the drama; “Heroes” is big hit in the U.S. Masi Oka or Masayori Oka (his real name is 岡政偉) is the hottest Japanese in the U.S now.
Masi Oka was born in Tokyo, and moved to Los Angels, California at 6 years old with her mother. He speaks English, Japanese and fluent Spanish. You can guess he is now American, but he still has Japanese citizenship.
What made Masi famous in the U.S is a popular drama, “Heroes” on NBC. The drama was started to broadcast in 2006, and Masi plays role in Hiro Nakamura. He speaks lines in both Japanese and English in the drama. The lines of Heroes are all written in English, so Japanese for Japan scenes lines are translated by Masi himself. With his effort, he produced a great Japanese saying in this drama. He says “Yatta!” when Hiro Nakamura done best in the drama. “Ytta! (やった！)” is used to show you are happy or that you approve of something in Japanese.
Masi started his career not as an actor but a developer of special effects for movies. He worked in “Star Wars Episode 1, 2”, and “Hulk” as a background staff.
In this connection I may add that he once appeared on the cover of magazine, “Time” as one of “Asian-American Whiz Kids”. His IQ is 189 ,and he went to Mirman School for gifted.
