Urusei Yatsura (うる星やつら, untranslatable pun regarding telling aliens to shut up) is a Japanese manga series written and illustrated by Rumiko Takahashi. It was serialized in Shogakukan's Weekly Shōnen Sunday from September 1978 to February 1987. Its 366 individual chapters were published in 34 tankōbon volumes. It tells the story of Ataru Moroboshi, and the alien Lum, who believes she is Ataru's wife after he accidentally proposes to her. The series makes heavy use of Japanese mythology, culture and puns. It was adapted into an anime television series produced by Kitty Films and broadcast on Fuji Television affiliates from October 1981, to March 1986, with 194 half-hour episodes. Twelve OVAs and six theatrical films followed, and the series was released on various home video formats.
The manga series was republished in different formats in Japan. Viz Media released the series in North America in the 1990s under the names Lum * Urusei Yatsura and The Return of Lum, but dropped it after eight issues. They re-licensed the manga and released an omnibus edition under its original title with new translations from 2019 to 2023. The television series, OVAs, and five of the films were released in North America with English subtitles, as well as a dub for the films by AnimEigo. They provided extensive notes on the series to allow people to understand the many cultural references and jokes in the series that would not normally be understood by non-Japanese. The remaining film, Beautiful Dreamer, was released bilingually by Central Park Media. Five of the films, as well as the OVAs, are available from MVM Films in the United Kingdom. The series was released on television in Southeast Asia as Lamu the Invader Girl. The series and films have been license rescued by Discotek Media for a Blu-ray release. A second anime television series adaptation of 46 episodes produced by David Production premiered on Fuji TV's Noitamina programming block in October 2022, exactly 41 years after the first premiered. That series is licensed by Sentai Filmworks and streamed on HIDIVE.
