Harry Endo was best known for his role playing Che Fong, a forensic scientist on the series Hawaii Five-O.
He had been working for Territorial Savings Bank in Hawaii and was being filmed in a commercial for his employer when he was approached about an acting role playing "Che Fong" as one of the original cast members in the television series Hawaii Five-O. Fong appeared in 111 episodes of the crime drama from 1968 until 1977, and reprised his role in a 1997-hour-long made-for-television movie.
After the series ended, he played some minor roles, including two episodes of Magnum, P.I. and appeared in single episodes of both Jake and the Fatman and Murder, She Wrote, before retiring from acting in the late 1980s.
