Most recently, Tadao had an appearance on Heroes in the episode "Don't Look Back", where he played Detective Furokawa, a Japanese-American police officer who translated for Hiro Nakamura in a scene near the end of the episode.
Tadao has also appeared in Diagnosis: Murder, The Tracey Ullman Show, the films Inspector Gadget and Godzilla, and many others.
When Tadao is not working as an actor, he is actively involved in Science Fiction fandom. Tadao can regularly be found at the Los Angeles Science Fantasy Society clubhouse in North Hollywood during meetings and/or events, and is regularly a Staff member at many fan-run conventions, including Loscon, Gallifrey One, Anime Los Angeles and many Worldcons and Westercons. He will be the Toastmaster at BayCon 2010.
His acting resume gives little credit to his attractiveness as a science fiction personality. As an entertainer moving through the social landscape of nerddom he reveals the many aspects of the acting persona he has created. Many of these have yet to be recorded to film. As an actor who is frequently not in loan his stories about gaining meaningful employment are an asset to many social settings.
As a comedic instructor he takes time with each individual in his seminars, to ensure there are upbeat critiques on timing, material, and delivery.
As a Japanese American he is mindful of his dual heritage and is easily persuaded to poke fun at both.
He is also a graduate of Crystal Lake South High School in Crystal Lake, Illinois
