Rika Ishikawa
She sang many of the lead lines in Morning Musume songs, especially after Natsumi Abe's graduation. She and fellow Morning Musume member Asami Konno were also lent to Country Musume, a group that features "Country Girls from Hokkaidō", such as Miki and Asami (the group has been known, however, to include members not from the rural island—such as former featured singers Rika Ishikawa and Miuna Saito).
