Kenichi Endō is a Japanese actor and voice actor born on June 28, 1961, in Tokyo. While he is primarily known for his extensive career in live-action film and television, often playing intense or villainous roles, he has also contributed his distinctive, deep voice to animated projects and Japanese dubs of foreign films.

In the realm of animation, Endō is recognized for his role as the antagonist Shunack in the 2006 anime film Origin: Spirits of the Past, also known as Silver-Haired Agito. His performance as the character from the past who seeks to rectify his mistakes is noted for its deep and commanding vocal quality. Another prominent anime voice role was in the 2017 feature film Mary and the Witch's Flower, produced by Studio Ponoc, where he provided the Japanese voice for the character Zebedee.

Beyond original animation, a significant portion of his voice work involves dubbing foreign productions into Japanese. This includes providing the Japanese voice for the character Groot in multiple films from the Marvel Cinematic Universe, such as the Guardians of the Galaxy series and Avengers films. He has also lent his voice to characters in video games, including Officer Phillips in Binary Domain and as the narrator for Let It Die.

Endō's career began in 1979, and he has since built a prolific filmography with hundreds of credits. He is affiliated with the talent agency EN's Tower. His work as a narrator for documentaries on television and in film is also a well-established part of his career. While information on recurring collaborations specifically within voice acting is limited, his broader acting career is marked by frequent work with prominent film directors such as Miike Takashi, Tsutsumi Yukihiko, and Harada Masato.
