Hiromi Sakamoto is a recognized director/producer whose work has been beneficial to the U.S.-Japan relationship especially in the fields of media and performing arts. He served as a drama director of NHK (Japan Broadcasting Corporation, the public broadcasting network of Japan) for several years, where he worked with many talented writers, composers and actors of Japan.
