Inspector Zenigata was first voiced by Shinsuke Chikaishi in the CinemaScope version of the 1969 , while Chikao Ōtsuka voiced him in the pilot's TV version. However, Gorō Naya was given the role when the first anime was actually produced (1971–72) and he continued to voice the character until 2010, with one exception. Due to budget concerns, TMS decided not to employ the regular voice cast for the 1987 original video animation "The Fuma Conspiracy", with Zenigata voiced by Seizō Katō. The 2011 TV special "Blood Seal - Eternal Mermaid" marked the first appearance of Kōichi Yamadera as the character and he continues to voice Inspector Zenigata to this day. Naya did return to the role once more for the 2012 "Lupin Family Lineup" short original video animation.
