4s4ki has announced the guest performers for the finale of their national tour, “4s4ki Oneman Live Tour 2025 ‘4444年 ; C4’,” set to take place on March 11 at Zepp Shinjuku in Tokyo. The event promises to be a standout moment, with an impressive lineup of collaborators who have previously worked with the artist on various projects.
Having successfully completed their first solo overseas tour in 2024, with the “4s4ki 極東周遊2024 ‘超喜猫仔/Hyper Happy Cat'” tour, 4s4ki followed up with a collaborative EP, “集合体大好病 / Collective Obsession,” featuring artists such as DÉ DÉ MOUSE and maeshima soshi. Later in December, 4s4ki released their fully self-produced EP, “慈愛equal自愛.”
Continuing to build on their momentum, 4s4ki kicked off 2025 with the release of “44th Dimension,” an EP co-written with Los Angeles-based electro music producer YULTRON under the 4s4ki×YULTRON name, released on January 29. In addition to the release, the artist will embark on a nationwide tour, beginning in February in Sapporo, Hokkaido, at cube garden.
For the March 11 finale, 4s4ki will be joined by a diverse and talented group of guest performers, including aviel kaei (CVLTE), Teru Ishige (the telephones), Itsuka (Charisma.com), OHTORA, Gigandect, gu^2, KOTONOHOUSE, Gokou Kuyt, Shakabouzu, DÉ DÉ MOUSE, Minami Nakamura, NUU$HI, Hanagata, maeshima soshi, and Masayoshi Iimori. All these guests are considered “friends” of 4s4ki, having previously collaborated with the artist on various musical projects, either as featured artists or co-writers. Furthermore, the concert falls on 4s4ki’s birthday, adding a special touch to the occasion.
Tickets for the finale concert are currently available for general sale on various ticket platforms. Fans are eagerly anticipating what promises to be an unforgettable performance with an exciting mix of 4s4ki’s creative collaborations.
