Hoshimachi Suisei, the powerhouse vocalist and Generation 0 member of COVER Corporation's VTuber agency Hololive, has been building serious momentum. Her subscriber count recently passed 2.93 million, and in March she launched her own agency, Studio STELLAR, to expand her music career.
During the November 12 finale of HOSHIMACHI SUISEI ARENA TOUR 2026 Once Upon a Stellar, she dropped two major announcements. Suisei will make her major-label debut through Sony Music's management and record label Echoes on December 9, 2026, with her first major-label single. She has also signed with U.S. talent agency WME.
Following the tour finale, officials confirmed that Hoshimachi Suisei had signed with WME. The global agency represents major artists including Bruno Mars, Billie Eilish, Adele, and Japanese singer Ado.
Suisei told fans, "I'll keep singing, so I hope you'll continue walking alongside me." Eight years into her career, she now has even more heavy-hitting partners behind her as she sets her sights on bigger stages.
Back in Japan, Sony Music's management and record label Echoes is an impressive new home for her major-label debut. Although the label was only established in 2024, its roster includes popular artists such as YOASOBI, MAISONdes, Tatsuya Kitani, and Eve.
Her first major-label single, "Datte Boku wa," arrives on December 9 as a two-CD release.
DISC 1: Features the major-label debut single "Datte Boku wa."
DISC 2: Features eight songs that have accompanied Suisei throughout her career so far, including "BIBBIDIBA" and "I don't care."
The package also comes with deluxe extras including an original necklace and a specially designed lyric card.
Suisei's music career has steadily expanded since she established her own agency in March. During the concert, she explained, "Now that I've established my own agency, I felt this might be the right time to take another step forward and enter new territory."
With a major-label debut in Japan and representation from a U.S. agency now in place, Hoshimachi Suisei is clearly preparing to take her career global.
