Hans Christian Andersen's The Little Mermaid (1975 film)

Hans Christian Andersen's The Little Mermaid (アンデルセン童話 にんぎょ姫, Anderusen Dōwa: Ningyo-hime; lit. 'Andersen's Fairy Tales: Princess Mermaid') is a 1975 Japanese anime film directed by Tomoharu Katsumata, based on Hans Christian Andersen's 1837 fairy tale "The Little Mermaid". Animated by Toei Animation, this film is close to Andersen's story, notably in its preservation of the original and tragic ending. The two main protagonists are the youngest daughter of the royal family, Marina, and her best friend Fritz, an Atlantic dolphin calf. In Japan, the film was shown in the Toei Manga Matsuri (Toei Cartoon Festival) on 21 March 1975.

The film was later released in the United States, dubbed into English by G. G. Communications, Inc. and Prima Film, Inc., in 1978, under the title: Hans Christian Anderson's The Little Mermaid (Andersen's name would be correctly spelled in subsequent releases).
