In early 2007, Morning Musume Tanjō 10nen Kinentai, a unit consisting of Kaori Iida, Natsumi Abe, Maki Goto, Risa Niigaki, and Koharu Kusumi, was created to celebrate the 10th anniversary of Morning Musume. They released a commemorative single called "Bokura ga Ikiru My Asia". The members chosen symbolize the beginning of the group; how they had five members ranging in age from 14–24. Additionally, each member was from an odd-numbered generation (Kaori Iida and Natsumi Abe from the first generation, Maki Goto from the third, Risa Niigaki from the fifth, and Koharu Kusumi from the seventh).
