Ennosuke Ichikawa IV, a highly respected Japanese kabuki actor, has also made select forays into voice acting for anime, with his known work being exclusively within the One Piece franchise. Born Takahiko Kinoshi on November 26, 1975, in Tokyo, he is a graduate of Keio University's Faculty of Letters, where he majored in Japanese literature. He made his first stage appearance at age five and formally entered the kabuki world in 1983 under the stage name Ichikawa Kamejirō II before assuming the prestigious name Ichikawa Ennosuke IV in June 2012.

His venture into voice acting is directly linked to his successful collaboration with the One Piece franchise. He starred in the live stage production Super Kabuki II: One Piece, where he portrayed multiple characters including Monkey D. Luffy, Boa Hancock, and Shanks. This involvement led to his casting as a guest voice actor in the anime specials. In 2015, he voiced the character Komei in the television special One Piece: Adventure of Nebulandia. He later voiced Gan Fall in the 2018 television special One Piece: Episode of Skypiea, taking over the role originally played by Jouji Yanami in the television anime.

Beyond these two specific voice credits, his professional filmography is predominantly composed of live-action roles in numerous television dramas and films. Examples of his extensive live-action work include roles in the NHK taiga dramas Fūrin Kazan and Ryōmaden, as well as the popular drama series Hanzawa Naoki, among many others. His career remains centered on kabuki, where he is known for his versatility in both male and female roles and his work in revitalizing the art form with Super Kabuki productions.
