Kenshi Yonezu and Hikaru Utada have teamed up for a brand new single, entitled “Jane Doe.” Released on September 22, 2025 (Monday), the collaboration track, written by Yonezu, between the modern J-pop superstar and the “First Love” hitmaker serves as the ending theme to the upcoming animé film CHAINSAW MAN – THE MOVIE: REZE ARC.

This follows Yonezu’s release of the movie’s theme song, entitled “IRIS OUT,” last September 15, 2025, alongside his hit single “KICKBACK” – a theme song for the popular CHAINSAW MAN animé series – becoming the first ever Japanese language song to achieve RIAA-Platinum status.

Alongside the release of “Jane Doe,” an accompanying music video also premiered. The music video is notably directed by Tomokazu Yamada, best known for directing the music videos for Yonezu’s “Lemon,” “Uma to Shika,” and “Sayonara, Mata Itsuka! – Sayonara,” as well as Utada’s “Mine or Yours,” “A Flower of No Color,” and “Gold -Mata Au Hi Made-.”

“I started working on the song without giving too much thought to who would sing it. However, as the song began to take shape, it
became evident that no one was better suited to it than Utada-san, so I reached out to them,” stated Yonezu in a press statement. “The moment Utada-san’s voice — melancholic, yet sweeping like a gust of wind — came in over the track, I remember being so moved that I let out a sharp gasp. As a songwriter, I feel truly honored to have been given this opportunity.”

“I knew I had to give it a go when I received this offer,” adds Utada. “Both of us being uncompromising singer-songwriters, we knew better than anybody else where the other comes from, but also faced the challenge of meeting halfway where our styles, as we found in the process, contrast. I hope everyone can feel the new sides that were brought out in us, as we remained true to ourselves and each other.”
