He is best known for portraying several heroic roles in tokusatsu, including Jiro in Android Kikaider and Goro Watari in Inazuman.
According to Ban in an interview in Otaku USA magazine, his casting was fairly typical, with him meeting Toei executives.
He has described Kikaider's story as "perfect", and expressed his desire for the series to be remade (he did not mention the anime adaptation released in 2000).
He played the title character on Inazuman, Ban was also a regular on Ninja Captor and Gridman the Hyper Agent.
Despite the iconic nature of his tokusatsu performances, he has said that he doesn't believe modern henshin hero shows have the same positive spirit as they once did, and that they are not able to excite children the way they used to.
