Shin Takarajima is a special anime that premiered in winter 1965, produced by Mushi Production.

About the production: the story comes from a other, there is 1 episode of about 55 minutes and its current status is "finished".

Its main genres are adventure, with themes such as Animals, Kids, Achromatic and Classic Literature.

On AniList, Shin Takarajima has an average score of 61%, an average score, and appears on 477 users' lists.

This was the first episode of Mushi Pro Land, a unique series of 60-minute animated programs. It was also Japan's first 60-minute animated TV program. However, the series never materialized and only this episode was actually aired. The story follows Stevenson's "Treasure Island," featuring characters in the form of animals. For example, the pirate Silver is illustrated as a wolf, where the main character Jim is changed into a rabbit. This has, therefore, nothing to do with the "New Treasure Island," Tezuka's masterpiece Manga. (Source: Tezuka Osamu Official Website)
