Morning Musume (モーニング娘。 Mōningu Musume.?), sometimes referred to as Momusu (モー娘。 Mōmusu.?), is a Japanese girl group formed in 1997 by rock singer-songwriter turned record producer Tsunku, who later composed a vast majority of the group’s songs over the decade. They are the lead group of Hello! Project that specialises in upbeat, pop-oriented music coupled with dance performance. The group produced several splinter groups, and often collaborates with other Hello! Project acts, including Country Musume, Berryz Kobo, Cute, Melon Kinenbi, and v-u-den. The group’s name can be translated as Morning Girls; as the name suggests, it consists of members mostly in their late adolescence and early 20s. The average age of the group members has remained more or less unchanged since its original formation because the group maintains a “school-like” system for their continuous line-up changes, with older members “graduating” and new, usually younger, members selected from nationwide auditions admitted to the group annually.
Since 2007, with their expansion into the Chinese-speaking market, the group officially adopted the name Jou An Sao Nu Jou (Chinese: 早安少女組; literally: “good morning girl’s group”). Since then, the group have been making a concerted attempt to break into new markets in Asia, Europe and the US, performing at EXPOs worldwide.
Morning Musume are one of the most successful Japanese pop idol girl groups, holding the second highest overall single sales (of a female group) on the Oricon charts as of February 2012, with the Oricon record of most top ten singles with an amount of 50, and they have sold over 21 million copies in Japan alone.
