In 2005, Mizuki appeared in a cameo role in "Yōkai Daisenso" ("The Great Yokai War") directed by Takashi Miike, a film about Yōkai inspired by his work as well as the work of Aramata Hiroshi. He appears towards the end of the film in the role of the "Great Elder Yōkai": a pacifistic character who condemns the warring ways of the film's antagonist and reaffirms the role of Yōkai as peaceful, playful creatures. A brief explanation about his works also is mentioned in the film. In 2010, NHK broadcast an asadora about his married life, "Gegege no Nyōbō", based on his wife's autobiography.
