What Is Studio STELLAR? Hoshimachi Suisei Announces Her Own Agency

On March 22, 2026 — her 8th anniversary and birthday — hololive VTuber Hoshimachi Suisei announced the establishment of her own personal agency, “Studio STELLAR.” The announcement was made during a special live stream on her YouTube channel, which boasts over 2.85 million subscribers, and sent shockwaves across the global VTuber community.

Is Hoshimachi Suisei Leaving hololive? The Truth About Her New Setup

The most important thing to understand about this announcement is that Hoshimachi Suisei is NOT leaving hololive.

According to Cover Corporation’s official statement, Suisei will continue her activities as a hololive Production VTuber, including collaborations and group events. However, her solo artist work — music releases, solo streams, new merchandise, and fan club management — will be handled by Studio STELLAR going forward.

This is not a simple graduation or independence. It is an unprecedented hybrid model: remaining under the hololive umbrella while operating her solo career through her own agency. Talent management will be handled by NERD Inc. in collaboration with Cover Corp.

Why Did Hoshimachi Suisei Start Her Own Agency? Her Goal: Tokyo Dome

During the announcement stream, Suisei stated her next major goal: performing at Tokyo Dome. She described the establishment of Studio STELLAR as “a positive decision to reach an even bigger stage,” and urged fans to support her on this new journey.

Cover Corp. echoed this sentiment, stating that the restructuring is essential for Suisei to pursue her ambitions in the mainstream music scene and achieve her Tokyo Dome dream.

With music production, live concerts, brand tie-ups, fan clubs, merchandise, and media appearances all scaling up rapidly, the traditional “talent under a single agency” model was no longer sufficient. Studio STELLAR is best understood as an operational optimization — not a rebellion, but a necessary evolution.

Hoshimachi Suisei’s Career Highlights — Why This Announcement Matters

Since her debut on March 22, 2018, Suisei has built one of the most impressive résumés in VTuber history. She became the first VTuber to appear on the iconic YouTube channel “THE FIRST TAKE.” Her 2024 hit “Bibideba” went viral worldwide, surpassing 100 million YouTube views and 100 million streams on Billboard JAPAN — both firsts for a VTuber.

The music video for “Bibideba” won a Bronze Award at the Clio Music 2025, one of the world’s top three advertising awards. She has headlined sold-out shows at Saitama Super Arena and Nippon Budokan, and was named to Forbes JAPAN’s “30 UNDER 30 JAPAN 2025” list — a recognition that transcends the virtual world entirely.

Studio STELLAR Arena Tour 2026 — “Once Upon a Stellar” Full Schedule

Alongside the agency announcement, Suisei revealed her biggest live tour to date: a 4-city, 5-show arena tour across Japan in 2026.

【Tour Schedule】
September 8–9, 2026: K Arena Yokohama (Kanagawa)
October 21, 2026: GLION ARENA KOBE (Hyogo)
November 7, 2026: IGA Arena (Aichi)
November 12, 2026: Marine Messe Fukuoka Hall A (Fukuoka)

Fan club “Hoshiyomi” members can access priority ticket lottery from March 22 to April 6, 2026. Additionally, Suisei’s music project with TAKU INOUE, Midnight Grand Orchestra, will hold their 2nd live “Project: Allegro” at Makuhari Messe on February 11, 2027.

What Does Studio STELLAR Mean for the VTuber Industry?

Cover Corp. described this move as “the next stage of VTuber culture.” And they may be right.

If Suisei’s hybrid model — staying within hololive while independently managing her solo brand — proves successful, it could open the door for other high-profile VTubers to pursue similar structures. The binary choice of “stay or graduate” may no longer be the only option for top-tier VTuber talent.

Suisei represents the clearest example yet of a VTuber transcending the streaming world to compete directly in the mainstream music and live entertainment industry. Studio STELLAR is not just personal news — it is a landmark moment in VTuber history.
