The story takes place on Sanagi Island in Kagawa Prefecture, famous as Cat Island.

With the cooperation of the islanders, the entire film was shot on location on the remote island, which would normally be difficult to do, and this sci-fi human comedy about Sanagi Island is sprinkled with the beautiful, idyllic scenery that is the island's charm!

The director and screenwriter is playwright Nomura Yuji, whose previous work "Sayonara" won numerous awards at film festivals both in Japan and abroad, including the Filmination Award at the Yubari International Fantastic Film Festival (Japan), the Best Crime Film Award at the Kokai International Film Festival (India), the Best Supporting Actor Award at the Wallachia International Film Festival (Romania), and was selected for the Foreign Film category at the Swiss International Film Festival.
Nomura, who is acclaimed for his works that combine pathos and laughter and make full use of his unique tempo and timing, carefully depicts the sad yet beautiful human (?) patterns surrounding the future, past and present of people who have chosen various places to live.

This quiet science fiction drama, uniquely Japanese, has been acclaimed at film festivals both in Japan and abroad, including the Minsk International Film Festival in Belarus and the Kokai Film Festival in India, for its unique folktale-like feel, which is created by the intermingling of everyday traditional scenery with the extraordinary that quietly appears next to it.
