Hoshimachi Suisei is making her major-label debut with Echoes, a label within Sony Music. Her debut single, "Datte Boku wa" ("Because I Am"), comes out on Dec. 9 on CD and streaming. She announced the news on Nov. 12 on stage at Marine Messe Fukuoka Hall A, during her arena tour "HOSHIMACHI SUISEI ARENA TOUR 2026 Once Upon a Stellar" (Real Sound, Nov. 13).

An answer song to "Stellar Stellar"

"Datte Boku wa" answers "Stellar Stellar," the opening track of her 2021 album "Still Still Stellar" and the song many fans know her by. Suisei co-wrote the lyrics with TAKU INOUE and came up with the title herself. It's a driving, determined anthem built to push the listener forward.

The fully limited CD edition is a two-disc set that also includes an acoustic arrangement she performed on this year's birthday livestream, packaged with an original necklace and a special lyric card.

A deal with WME, too

At the same show she announced a deal with WME, one of the world's largest talent agencies. In March she launched her own management company, Studio STELLAR, as she expanded her solo career. Now she has a Japanese major label and a global agency in her corner at the same time.

Our take

An artist who grew up singing on YouTube, alongside her fans, is now teaming up with a global agency. It feels like one more road for Japanese music to reach the world. The single drops Dec. 9 — start with "Stellar Stellar" if you haven't heard her yet.
