Was best known as the voice of Inspector Koichi Zenigata in the Lupin III anime franchise which he has done for 41 years until he retired from the role.
Voiced Sam the Eagle in the Japanese dub of 'The Muppet Show', alongside Yasuo Yamada as Kermit the Frog.
He attended Yasuo Yamada's funeral. When he saw Yamada's picture, Naya tearfully said in his Zenigata voice, "Hey, Lupin, who should I chase from now on? Who should I chase if you die?".
Because I'm an actor, I thought it was my job to act in various ways according to the role I was given. That's why I never thought of myself as a voice actor.
Zenigata never gets old, but I get older year by year, so it's a little bit difficult to match.
