I need to verify the correct name of the group she was in during 2021. She was in Nogizaka46's 1st generation, right? Yes. So in 2021, her activities would include group concerts, music programs, maybe some solo projects. I should also check if she was in any TV shows or variety programs that year.

Another thing to consider is how Japanese idol groups structure their activities. Typically, members participate in various events, which might include both local and national tours. In 2021, due to the pandemic, maybe some events were held online or with limited capacity. That could also impact her performance schedule.

2021 saw Kitano continue to serve as a leader within Nogizaka46, balancing group responsibilities with individual projects. She made appearances on variety shows like The New Music on! and Countdown Live , contributing to the group’s public image. Additionally, her solo performance in the Nogizaka46 theater plays further highlighted her acting abilities, broadening her artistic profile. While she did not release a solo single that year, her consistent presence in the group’s activities underscored her reliability and commitment.

Another angle is her personal life before marriage. The user might be interested in her career trajectory and how it was affected by her decision to marry. Since marrying can have implications on a career in Japan, especially for female idols. I should mention how she balanced her career with her decision to get married.
