Hitori Gekidan is the stage name of Shogo Kawashima, a Japanese entertainer born on February 2, 1977, in Chiba Prefecture, Japan. While his career is primarily centered on being a comedian, actor, novelist, and film director, he has also contributed his voice to a small number of anime film projects.

His stage name, Gekidan Hitori, translates to one-person troupe, reflecting his solo comedy style. He began his entertainment career in the mid-1990s and gained prominence as a versatile performer, with his acting work in live-action films such as Memories of Matsuko and Golden Slumber being particularly noted.

In the realm of anime, he is known for two specific voice roles. He provided the voice for the character Yoshirō in the 2012 anime film Fusé: Memoirs of a Huntress. His other major anime voice role was as Singh, a boy from India, in the 2015 film Eiga Chibi Maruko-chan: Italia kara Kita Shōnen (Chibi Maruko-chan: A Boy from Italy). He was also part of a group of celebrity guest voice actors for this film, which marked the return of the Chibi Maruko-chan anime to theaters after 23 years.

Beyond these two film credits, his documented work as an anime voice actor is sparse. His broader career includes a vast number of television variety show appearances, live-action dramas, and films, as well as work as a screenwriter and director. Due to the limited scope of his verified anime voice acting credits, no recurring collaborations with specific anime directors or studios, nor any notable achievements specifically for anime voice acting, can be identified.
