tripleS Tokyo Concert 2025: Japanese EP Release Date & US Tour Announced
K-pop group tripleS successfully wrapped up their first complete 24-member concerts in Japan while revealing two major upcoming projects during the Tokyo shows.
tripleS held "A Live 25 in Tokyo" at Kanadevia Hall (formerly Tokyo Dome City Hall) on July 19-20, 2025, marking their first full group concert in Japan. The shows attracted approximately 4,000 WAV (their fandom name) across both nights.
The performances showcased the group's journey from their debut dimension Acid Angel from Asia through their latest full group activities, featuring various sub-unit configurations and demonstrating what the company called "the overwhelming presence that only 24 members can deliver."
tripleS's latest album ASSEMBLE25 sold 516,626 copies in its first week, more than tripling the first-week sales of their previous release ASSEMBLE24, which sold 152,335 copies. This achievement made the group rank fourth in the list of highest first-week album sales by girl groups in 2025.
The group also achieved multiple music program wins with their title track "Are You Alive."
During the Tokyo concerts, tripleS ∞! (Hatchi!) announced their debut EP "SecretHimitsuBimil" will be released on October 1, 2025. The unit consists of members YooYeon, Mayu, Kotone, ChaeYeon, JiWoo, ShiOn, ChaeWon, and SooMin.
The title combines "secret" in three languages - English, Japanese (Himitsu), and Korean (Bimil). The unit will also hold a live concert on November 2 at Tokyo's Toyosu PIT.
tripleS announced their "Alpha Percent" world tour featuring a new eight-member unit called tripleS Alphie, consisting of YooYeon, Kotone, Nien, Lynn, HaYeon, ShiOn, ChaeWon, and JiYeon.
The North American leg will kick off in Toronto on September 3 before visiting New York (September 5), Indianapolis (September 7), Chicago (September 9), Dallas (September 12), Denver (September 14), San Francisco (September 17), Los Angeles (September 19), and Vancouver (September 22).
tripleS markets itself as "the world's first decentralized KPOP idol group made by its own fans", allowing fan participation in sub-unit formation and concept decisions through their blockchain-based system.
The group continues expanding their international presence with simultaneous activities across multiple markets while maintaining their core identity as "The Idol of All Possibilities."
