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.

Comet in Moominland is the second in Finnish author Tove Jansson's series of Moomin books. Published in 1946, it marks the first appearance of several main characters, such as Snufkin and the Snork Maiden.
