Yoshio Kojima is a Japanese entertainer known primarily for his work as a comedian, with his profile listing his birth date as November 16, 1980. His involvement in anime voice acting is limited, with his most notable roles being in the early 21st century.

Kojima provided the voice for the character Note in the 2019 anime film Korasho no Kaitei Wakuwaku Daibouken!. This film, produced by TMS Entertainment, is based on the Korasho character from Benesse's Shinken Zemi correspondence course for elementary school students. His casting as the film-original character Note was part of a voice cast that included established professional voice actors.

In 2018, he voiced the character Jinjin in the television series Hugtto! Precure. Jinjin is a recurring character depicted as a suited subordinate to the villain Zeroth, part of a comedic duo with another character named Takumi. Information on Kojima's performance in this role notes that he is a comedian rather than a dedicated voice actor, and his work received attention for its distinctive character interpretation.

Beyond these two specific credits, there is no readily available information on recurring collaborations with specific directors, studios, or a broader body of significant work in anime voice acting. His filmography is predominantly composed of live-action television and film appearances, reflecting his primary career as a performer. Consequently, there are no documented major achievements or awards for Kojima specifically within the field of anime voice acting.
