"Vivarium" (Japanese: ビバリウム) is a song written and recorded by Japanese singer Ado, released on February 18, 2026, via Capitol Records. The song accompanies the biography novel Vivarium: Ado and Me, written by Narumi Komatsu.

Background and release

On January 10, 2026, Ado announced a biography novel of herself, Vivarium: Ado and Me. Written by Narumi Komatsu, the biography is based on Ado's own account of her early childhood and eventual foray into the music scene.[2] Alongside the announcement of the novel, Ado shared she wrote and recorded an accompanying song, "Vivarium".[3]

"Vivarium" was released on February 18, 2026, as a digital single.[4]

Cover artwork

On February 14, Ado revealed the cover art for "Vivarium". The cover art was noted to be her first one taken "in real life" rather than featuring a hand-drawn character.[5] The artwork features a photo of Ado's backside in a closet.[6]

Music and lyrics

In an interview with Billboard Japan, Ado described "Vivarium" as a song where she is "talking to her current self".[7] Encore described "Vivarium" as "a vocal rock song where Ado searches for light despite suffering from self-denial."[6]

Music video

A music video for "Vivarium" was teased by Ado's staff on social media shortly after the digital release of the song. On February 27, her staff announced a music video for "Vivarium" would premiere on her YouTube channel on February 28.[8]

Directed by Kyotaro Hayashi, the music video for "Vivarium" is Ado's first live action music video.[9][10] Various news outlets reported around 300 takes were recorded for the music video.[11][12][13] Ado said that it was her idea to create a live-action music video for "Vivarium".[14]

The music video came to widespread attention due to several shots depicting her in a real-world location.[14][15][16] Although she had appeared obscured at concert performances, this was Ado's first unobscured appearance in a music video.[15] Several social media users remarked about the video's depiction of her face, with one fan remarking that they were unaware of Ado's human nature until then.[15][16] An insider at the music industry told Nikkan Gendai that this decision was likely due to her new career as a music producer.[17]

The video features animated segments depicting her illustrated persona, with Ado's long-time image director Orihara and the animation studio Bees Inc. producing the segments, interspersed throughout the live-action footage.[18]
