It was the first full-length Moomin film, and serves as a prequel to the 1990 anime series Moomin, introducing characters that would later appear in the series. It was released in Japan first theatrically on August 8, 1992 as a triple-feature with two unrelated shorter films, and was later released on home video with 10 minutes of extra footage. The original Japanese release of the film was scored by Sumio Shiratori, re-using compositions that were created for the anime series. In addition, he composed two new opening and ending songs for the film—"Shiawase no morugaane" and "Kono uchuu he, tsutae tai", respectively, both sung by Emiko Shiratori. The international version of the film featured a new musical score composed by Pierre Kartner. The film was later released in Europe, and has been dubbed to several European languages. It was the seventh most watched film in Finland during the 1992/1993 season with 166,738 viewers.

The film's re-release was halted indefinitely as a result of the COVID-19 pandemic, with it yet to be officially released.
