Born in Hiroshima, Japan, Masaharu Morimoto is recognizable to “Iron Chef” fans as the serious chef who consistently creates artistic and delicious Asian fusion dishes. A star of the Japanese cooking competition that spawned “Iron Chef America,” Morimoto has been a dominant presence on both shows. The 56-year-old chef and restaurateur opened his first restaurant in Japan in 1980, before moving to the United States five years later. He owns restaurants in New York, Tokyo and Mumbai, has a line of sake and beer and is the author of “Morimoto: The New Art of Japanese Cooking.”
