Kunpei Sakamoto

Kunpei Sakamoto’s Path from Stage to Voice Booth

Before the recording booth, there was the stage. Born October 10, 1965, in Tokyo, Kunpei Sakamoto entered the Gekidan Himawari training program after high school, then made his screen debut at just 19 in a Nikkatsu production. Through his twenties and thirties, he served as a lead performer in Gekidan Shu Kuri-mu, a Tokyo theater troupe where he fronted nearly every major production from 1986 through 2005. His seiyuu career launched only after his yakudoshi years – the traditional unlucky ages in Japanese culture – a late start that would prove anything but inauspicious. He joined Ken Production, the agency he still calls home, and quickly accumulated credits across Korean drama dubbing during the Hallyu wave, including a prominent assignment dubbing J.Y. Park in Dream High.

The Star Fox Legacy and Nintendo’s Lylat System

The role that defines Sakamoto’s gaming legacy is Peppy Hare, the elder advisor of Team Star Fox and perhaps the most quoted character in Nintendo’s classic space shooter franchise. He inherited the character for Star Fox 64 3D in 2011, taking over from Tomohisa Aso, and simultaneously voiced James McCloud – Peppy’s fallen comrade and Fox’s father – in the same title. Both performances carried over into Star Fox Zero in 2016, a full reimagining of the original game. In 2026, Sakamoto returned to the role once more for Nintendo’s Star Fox remake developed by Velan Studios for Nintendo Switch 2, cementing his status as the definitive modern voice of Peppy Hare in the Japanese version of the franchise. The character’s weight – a grief-marked mentor figure carrying guilt over James McCloud’s death while guiding a young Fox – demanded emotional range that Sakamoto brought across multiple releases spanning 15 years.

Anime Credits and the Breadth of Supporting Work

Across the anime landscape, Sakamoto built a career largely through character work rather than leads, accumulating appearances in titles covering almost every major genre. He played Renjiro Ayabe in Danball Senki Wars, Manninger in Kakumeiki Valvrave, and Tomoaki Iwakura in Btooom! On the prestige end of the spectrum, he appeared in Attack on Titan The Final Season and the OVA Attack on Titan: Lost Girls. Karakuri Circus, Legend of the Galactic Heroes: Die Neue These, and Concrete Revolutio all carry his name in their supporting casts. Across the Maji de Fumajime Kaiketsu Zorro franchise, he voiced multiple recurring roles across three series between 2020 and 2022.

Dubbing, Games, and Cross-Media Breadth

Sakamoto’s dubbing work spans American procedurals, Korean dramas, and Hollywood films. Among his most consistent assignments is the character of Roman across CSI: Miami, alongside recurring appearances in The Killing and Criminal Minds: Suspect Behavior. In games beyond Star Fox, he voiced Hatono in Muramasa: The Demon Blade, contributed to Medal of Honor’s Japanese localization, appeared in Final Fantasy: Type-0 HD and Lightning Returns: Final Fantasy XIII, and voiced Pablo Millan in both Detective Pikachu and Detective Pikachu Returns. On Starlink: Battle for Atlas, he reprised the Peppy Hare role in the Japanese version once more.
