One day, while playing on the rocky beach under the cliff, he found a mermaid Bonio, whose head was trapped in a glass bottle. Sosuke saved Ponyo and raised her in a green plastic bucket.
Ponyo and Sosuke are infatuated with each other. She made up her mind to become a human little girl and return to Sosuke, so Ponyo decided to run away from home and finally get together.
Extended data:
When Miyazaki Hayao conceived the film, he listened to Wagner's opera Valkyria. At first, Jin Yuji's name was "Brunside" (a character in Valkyria). Later, when Miyazaki Hayao was painting, he had a whim and changed it to "Ponyo".
The name of the young hero Sosuke comes from the character Nonaka Sosuke in Natsume Sosuke's novel Door (in Japanese, "Sosuke" and "Sosuke" are pronounced the same).
During the release of Hal's Moving Castle, Ghibli members collectively went to a small town near Seto Inland Sea for a holiday. Miyazaki Hayao likes the traditional houses there. Everyone lives in a hotel on a cliff with a view of the sea. This trip gave birth to goldfish princess on the cliff.
