Kamimura had wanted to become an idol due to her admiration of Miho Watanabe.

She first appeared in the group's concert on December 13 at the Nippon Budokan. Her catchphrase is When she joined Hiragana Keyakizaka46, she was its only third generation member, until the three other members joined her in February 2020; this has drawn comparisons to Neru Nagahama, who was the only member when Hiragana Keyakizaka46 was formed.
Kamimura is the first Hinatazaka46 non-founding member to have released a solo song, released on the group's third single in 2019. In 2023, she became the center (lead performer) of the group's tenth single title song, "Am I Ready?".

It sold 36 thousand copies in its release week and topped the Oricon Weekly Photobook chart. The same year, she starred as Serufu Yua in the live-action adaptation of the animated series Do It Yourself!!, originally aired on Mainichi Broadcasting System and TBS Television.
Having been part of the lineups of all Hinatazaka46 title songs up to 2025, Kamimura was not selected for that of the group's 2026 single, "Cliffhanger", and instead became the center of the non-selected team, , making her the first member to have been both title song and Hiragana Hinatazaka46 center. In an interview, she commented that she had always "respected" Hiragana Hinatazaka46 and hoped to "make a lot of eye contact".
Yohei Nakayama of Real Sound described Kamimura as a "unique" character who combines "seriousness" and "surrealism", and she has been noted for her inventive use of words. Nakayama also remarked that the rock-style dance music of her solo song was "unexpected from a Sakamichi group" and compared her "cool and powerful" singing voice to that of Ami Suzuki.
