Gorō Naya

Naya's association with One Piece appears among the anime's extended Japanese voice credits, though the particular character he portrayed is not documented in publicly available sources. Minor or archival credits of this kind were not unusual late in his career, when he continued limited voice work alongside his primary commitments in theatre.

Goro Naya was a Japanese actor born in 1929 who died in 2013. He worked for decades as a stage actor, narrator, and voice performer, becoming one of the most recognizable voices in Japanese animation.

Naya most famously performed Inspector Zenigata Koichi across the decades-long Lupin the Third franchise, a role that made him one of Japanese animation's most recognizable voices.

Naya was the older brother of fellow actor Rokuro Naya, making the two the only sibling pair from the family known to have built careers in Japanese show business. Beyond this family tie, no further relatives are documented in connection with Goro Naya's professional life.

Naya spent his entire professional life as a member of the Theatre Echo troupe, a commitment that ran alongside a screen career stretching from 1951 into 2012.
