Aimyon will release her first-ever best album, "AIMYON BEST ALBUM - Kuchibiru wo Oe! -," on September 9.

The release commemorates the singer's 10th anniversary since her major-label debut, which she will celebrate on November 30.

The collection will feature every single and B-side released throughout her major-label career, spanning from her 2016 debut single "Ikite Itandayona" to 2025's "Sketch / Kimi no Yume wo Kikinagara, Boku wa Waraeru Idea wo!," which were used in 'Doraemon the Movie: Nobita's Art World Tales.'

The album will be available in regular and limited editions. The three-disc set will include all of Aimyon's singles along with a selection of fan-favorite B-sides, while the limited edition will come with a bonus fourth CD featuring her new song "Kyou wa Hare, Hadasamui. Watashi wa Ie, Guitar wo Hiku."

A teaser video was also released alongside the announcement. In the clip, Aimyon takes on a challenge in which she must quickly identify and sing along to instrumental versions of her own songs. Although the songs are her own, Aimyon surprisingly struggles to recall some of them.
