Earnest Higa's life is all about being bicultural in Japan and the United States. He has used this aspect of his character in his career, spending the past 24 years making sure U.S.-based Domino Pizza fits in Japan.

"I was lucky to have both cultural backgrounds," the 56-year-old Hawaiian, who has spent three-quarters of his life in Japan, said in the Tokyo office of his company, Higa Industries.

Born in Honolulu to second-generation Japanese immigrants, Higa moved to Geneva at the age of 7 and two years later came to Tokyo, where he lived for nine years and attended the American School in Japan in Chofu.
