Suisei Hoshimachi (星街すいせい), one of the biggest names in virtual music, has announced her major-label debut. She will join Echoes, the management and label arm of Sony Music Entertainment, with the debut set for December 9.
She made the announcement on November 12 during the Fukuoka stop of her four-city arena tour, “HOSHIMACHI SUISEI ARENA TOUR 2026 Once Upon a Stellar.” She closed the main set by performing a new song, “Datte Boku wa” (だって僕は), for the first time. The show ended on an emotional note.
Her management office, Studio STELLAR, confirmed the news on its official X account and labeled it a “major announcement.” The major debut single is also titled “Datte Boku wa.” A full-production limited edition CD package has been announced, and pre-orders are open.
Two new tours planned for 2027
Alongside the debut, Studio STELLAR announced two tours for 2027. The first is a joint-bill tour called “Metamorphose.” A joint bill, known in Japan as a taiban tour, pairs an artist with other acts on the same program. The second is an Asia tour called “NEVER LANDING.” Details for both will be released at a later date.
What is Echoes?
Echoes was launched by Sony Music Entertainment on September 12, 2024, as a combined management company and music label. Its current roster includes YOASOBI, Ayase, Rira Ikuta, MAISONdes, Aooo, asmi, Eve, Tatsuya Kitani, NOMELON NOLEMON and Hump Back.
Hoshimachi already has a link to the Echoes family. This year she performed at the CENTRAL MUSIC & ENTERTAINMENT FESTIVAL 2026, a music festival that featured many Echoes artists. According to PANORA, she sang under the night sky in Yokohama.
Who is Suisei Hoshimachi?
Suisei Hoshimachi is a virtual singer and VTuber (a performer who appears online as an animated avatar) affiliated with the agency hololive production. She also operates through Studio STELLAR, the individual office she set up. She announced its founding at a press conference. At that event she described the office as a “secret base” for realizing what she wants to do.
Her live career has grown steadily. It includes a show at Nippon Budokan, the famous Tokyo arena, and a 2024 tour called “Spectra of Nova.” Her song “Bibidebi” topped the 2024 annual VTuber ranking compiled by User Local. It was reportedly the first track in that ranking to pass 100 million views.
The move to Sony Music’s Echoes label adds a major-label partner to a career that has so far been built largely through the VTuber scene and her own independent office.
Author’s Comment
Let me be clear: a VTuber filling arenas and then signing to a major label is not a novelty act anymore, it’s the industry catching up to what fans already knew. I love that she chose to tell her fans in the middle of a live show, because that’s how you give people a moment they’ll talk about for years. Japanese labels tend to move slowly and cautiously, so seeing Echoes bring her in tells you something about where the music business thinks the audience is. Now I just want to see what the Asia tour looks like. Please, someone start saving up for tickets.
