Haromoni (ハロモニ@) was the sequel to the long-running Japanese variety show Hello! Morning, which first aired on April 8, 2007, on TV Tokyo and later throughout the country. The show was recorded in HD and starred Morning Musume members. Each member represented different animals living under the young and mildly despotic ruler of the fictional Kingdom of Haromoni, King Akachin (あかちん国王), whose name derives from the Japanese word for "baby" (赤ちゃん, akachan).

The final episode aired on September 28, 2008.

Haromoni marked a departure from its predecessor and related Hello! Project productions in that it was shot exclusively outdoors and was composed of a series of connected segments. In the first ten episodes, the show followed the form of a relatively cohesive narrative, detailing the weekly accomplishment of a specific task. The tasks generally consisted of delivering a given piece of hardware used in commerce and industry on behalf of King Akachin.

Thereafter, the show focused primarily on several distinct characters, including Lying Queen (うそつQUEEN), Little King (チビッコKING), Hit Jack (ヒットの現場JACK) and Child Gourmet Joker (お子さまグルメJOKER). Morning Musume members were usually split into two groups who then challenged other Japanese celebrities to compete in a series of one or more games for each character.

In the episode 'Lying Queen', for example, four Musume members faced off against a celebrity artist in a game to determine which of them was lying about a given subject (past gastronomic experiences, among others). At one point, a third group, consisting of Koharu Kusumi and Aika Mitsui, visited Chinese restaurants and events related to China in order to learn more about Eighth Generation members Junjun and Linlin's home country.

Other challenges included creating an exclusive character design for the Kirarin Revolution anime series. Members were asked to draw the design for Tsukishima Kirari's pet cat Nā-san's antagonist. Sayumi Michishige's youma-inspired design was chosen from the submitted works.

From the January 27, 2008 episode until the April 27, 2008 episode, Haromoni@ had consisted of only a "MouTube" segment and occasionally a studio performance.
