Hayao Miyazaki's (Howl's Moving Castle) next animated flick, Gake no ue no Ponyo (Ponyo on a Cliff) will be released by Toho.

Variety notes the film follows a goldfish princess named Ponyo who wants to become human and her relationship with a 5-year-old boy. Miyazaki, who is writing the original script, is basing the boy on his grandson, the son of Tales From Earthsea helmer Goro Miyazaki. The seaside setting is inspired by the director's 2005 stay on Japan's Inland Sea, renowned for its scenic views.

No production has been set for Ponyo on a Cliff.
