Kitagawa Rio was born on March 16, 2004 in Tokyo, Japan.
On June 22, she was announced as a winner of the Morning Musume '19 LOVE Audition and would join Morning Musume '19 as a 15th generation member alongside Okamura Homare and Yamazaki Mei. They were introduced on stage during the Hello! Project 2019 SUMMER concert tour from July 13 and will begin performing with the group in the Morning Musume '19 Concert Tour Aki.
On August 28, Kitagawa, Okamura, and Yamazaki held their debut fanclub event, Morning Musume '19 15ki Member FC Event, at Yamano Hall.
On September 5, the 15th generation members began a fanclub-exclusive web talk show, titled Three stations.
On March 25, she was scheduled to celebrate her 16th birthday at a fanclub event titled Morning Musume '20 Kitagawa Rio Birthday Event, featuring two shows at LANDMARK HALL. However, it was cancelled in consideration of a new policy established by the government to prevent the spread of the coronavirus. It was later rescheduled.
When Kitagawa joined Morning Musume, she was in her last year of middle school. As of April 2020, she is currently in her first year of high school.
A list of nicknames that have been used to refer to Kitagawa Rio:
- Kitario (きたりお): Her nickname as a member of Morning Musume.
- Rio (りお): A nickname she wrote on her Morning Musume '19 LOVE Audition application.
- Mizunomi Babaa (水飲みババア; Water-Drinking Granny): A nickname given to Kitagawa by her classmates, which she wrote on her Morning Musume '19 LOVE Audition application. On a school sports day, she had muscle pain and wasn't feeling well, so she collected and drank all the extra water that no one else wanted. Because her classmates thought she was like an old woman, they called her "Mizunomi Babaa".
