Suisei Hoshimachi's arena tour Once Upon a Stellar ends with a Fukuoka show on November 12, screened live in 51 Japanese theaters and in cities across Asia and Australia. The tour runs under her personal office, Studio STELLAR.
Suisei Hoshimachi's coverage in 2026 splits between a stadium-scale tour and a one-off appearance at a professional baseball game. The larger thread is the arena tour Once Upon a Stellar. Its final performance, in Fukuoka on November 12, will be broadcast live to 51 theaters and venues in Japan and to venues in Taipei, Hong Kong, Macau, Seoul, Singapore, Kuala Lumpur, Jakarta, and Melbourne. Domestic tickets are 5,000 yen. The tour is identified as the first large-scale live project under Studio STELLAR, Hoshimachi's personal office.
Earlier in the year, Hoshimachi appeared at a Chiba Lotte Marines game alongside Hatsune Miku. The two threw the first pitch on a Monday, with Hoshimachi appearing on the pitcher's mound via screen and delivering the pitch to Marines player Shingo Ishikawa. The appearance was part of Lotte's summer ice cream campaign.
The two stories share a pattern: Hoshimachi's activities are staged for audiences outside a standard concert or stream setting, whether at a ballpark or in cinemas across several countries. The tour finale is the more concrete of the two, with a fixed date, a fixed venue count in Japan, and named cities abroad. The Marines appearance is a single-day event tied to a corporate campaign, and the sources do not connect it to the tour or to Studio STELLAR. Nothing in the coverage states what follows the tour or the ballpark appearance.
