In April 2001, group leader Yuko Nakazawa left to focus on her solo career (stating her age as a factor as well—she felt it was limiting her ability to meet the physical demands of the group's activities) making Kaori Iida and Kei Yasuda Morning Musume's co-leaders. During this time, Rika Ishikawa was "lent" out to the rather inactive group, Country Musume. She did not officially join, but participated as a feature singers in number of their singles.
