Equally prominent is her role as Krillin in the Dragon Ball franchise, a character she has voiced for decades across Dragon Ball, Dragon Ball Z, Dragon Ball Super, and numerous films such as Dragon Ball Super: Super Hero. She also voices other characters in the series, including Yajirobe and the Fortune-teller Baba.

Beyond these global phenomena, Tanaka has an extensive and diverse filmography.
