Tokyo talent agency Starto Entertainment announced on September 24, 2026, that the popular WEST idol group will officially cease all collective activities on September 30 [3]. The decision concludes twelve years of group performances following weeks of internal discussions sparked by the impending departure of two founding members [1]. Although the ensemble will no longer release music or stage concerts under a unified banner, all seven performers intend to remain under contract with the agency as individual talents [3].
WEST Idol Group Finalizes Formal Activity Conclusion
Corporate executives at Starto Entertainment Inc., led by Representative Director and CEO Katsuaki Suzuki from their headquarters in Tokyo’s Minato Ward, formally published the resolution regarding WEST. (formerly Johnny’s West) on Thursday, September 24, 2026. Management outlined that the conclusion of unit activities was reached after comprehensive deliberations concerning the artistic direction and personal aspirations of every performer. The agency acknowledged that concluding group operations was a difficult resolution after more than a decade of shared musical output. Suzuki signed the announcement [3].
Fans received a formal apology from leadership for the extended duration required to reach a definitive consensus following the initial departure announcements in late August. Agency officials explained that navigating future obligations while examining whether the group could realistically continue required delicate, multi-party evaluations. The resulting delay generated substantial concern across the domestic entertainment landscape as audiences awaited clarification regarding scheduled concerts and ongoing commercial campaigns [3].
The decision directly impacts the WEST idol group branding that has anchored the agency’s musical roster since autumn 2023. With activities ceasing on September 30, live group concerts, prospective ensemble singles, and collaborative broadcast appearances will draw to a close [1]. Both domestic broadcasts and prospective commercial contracts will adapt to the cessation of joint appearances. Group projects officially halt before October [3].
The sudden dissolution highlights the intricate organizational coordination that Japanese agencies undertake when historic boy bands alter their performance configurations [1]. Starto Entertainment maintained that preserving the individual artistic dignity of every member remained their guiding priority throughout the weeks of bilateral discussions. Joint stage performances end completely on September 30 [3].
Departure of Ryusei Fujii and Nozomu Kotaki
The primary catalyst for the shutdown emerged on August 30, 2026, when Starto Entertainment disclosed that members Ryusei Fujii and Nozomu Kotaki had determined to exit the seven-member formation. During ongoing dialogues regarding upcoming commercial projects, both Fujii and Kotaki formally submitted requests to depart WEST. so that they could pursue independent creative opportunities outside the boy band structure. Agency leadership chose to accept their resignations out of deep respect for their individual convictions after extensive internal discussions [2].
Organizers faced immediate operational revisions across scheduled live appearances following the departure disclosure. The unit was slated to take the stage at the prominent KAMIGATA EXPO PARK FES 2026 music festival, but coordinators determined that performing as a full seven-person lineup had become impossible. Management promptly announced full ticket refunds for disappointed ticket holders who had purchased admission to see the ensemble. Ticket refunds followed immediately [2].
Following the announcement regarding Fujii and Kotaki, the agency initiated extensive consultations with the five performers: Daiki Shigeoka, Akito Kiriyama, Junta Nakama, Tomohiro Kamiyama, and Takahiro Hamada. Executives deliberated whether reforming into a quintet was a viable long-term strategy for WEST., or whether continuing without two key vocalists would dilute their established artistic identity [1]. Ultimately, the five remaining members concluded that closing the group chapter was preferable to an altered continuation [3]. Both departing members joined in 2014 [2].
The remaining five vocalists evaluated their personal artistic aspirations together with their commitment to the group’s long-standing public reputation. Five members rejected the quintet format [3].
How Long Do Idol Groups Last?
Observers analyzing entertainment dynamics frequently examine how long do idol groups last across the demanding Asian music ecosystem, where intense physical regimens, rigorous public expectations, and shifting contractual milestones typically restrict group lifespans to between five and seven years. Sustaining active momentum for more than a full decade represents a notable achievement within contemporary idol culture. When Johnny’s West stepped onto the national scene in 2014, the seven performers entered a fiercely competitive landscape dominated by entrenched agency legacies [1]. Reaching twelve continuous years of collective recording and touring placed the ensemble among the most resilient male idol units in Japanese pop history before divergent career aspirations prompted their final transition [3]. Their extensive discography highlights sustained creative resilience across competitive domestic charts [1].
Media observers also track why musical groups across Asian markets dissolve after passing their initial contracts. Many idol units disband when members cross into their thirties and seek specialized creative outlets such as theatrical acting, television hosting, or independent music composition that clash with demanding group tour schedules. The unit released music for 12 years [1].
Japanese entertainment agencies frequently manage sudden schedule shifts and production pauses, as illustrated when a Gachiakuta manga research break continues under Kodansha while creative staff reorganize upcoming project commitments. In idol management, coordinating seven distinct schedules across stage plays, variety television, and studio sessions presents perpetual logistical friction. Resolving that friction often necessitates allowing individual members to direct their own professional calendars [3].
The longevity of the WEST idol group demonstrates that strong camaraderie can extend a unit’s lifecycle well beyond typical industry averages for idol groups in japan [1]. Maintaining synchronized schedules across seven adult professionals eventually becomes unsustainable when individual career priorities branch into distinct media sectors. Group activities concluded naturally after twelve fruitful years [3].
Johnny’s West Rebranding and the Smile Up Scandal
The history of WEST. connects deeply to profound structural upheaval across Japan’s talent sector. When the group formed in 2014, they debuted under the name Johnny’s West, explicitly carrying the moniker of talent agency Johnny’s & Associates. Their early career flourished under that legacy banner through nationwide arena tours and top-charting studio singles. The group debuted in 2014 [1].
Public scrutiny intensified following extensive revelations detailing historical sexual abuse perpetrated by late agency founder Johnny Kitagawa. In autumn 2023, the managing company rebranded as Smile Up in an effort to provide victim compensation, subsequently establishing Starto Entertainment to oversee commercial artist representation under incoming president Atsushi Fukuda. To sever connections with the disgraced founder’s name, the performers dropped ‘Johnny’s’ and renamed themselves simply WEST. (with a period) [1].
The rebranding allowed the seven members to continue performing without carrying the institutional founder’s disgraced title across public broadcasting networks. Seven members preserved their union [1].
Nevertheless, operating as an established WEST idol group within the reconstructed agency landscape imposed new strategic pressures on each artist [1]. The transition highlighted how legacy boy bands navigate structural modernization while managing shifting corporate ownership [3]. The performers demonstrated exceptional resilience by sustaining their fan base throughout the administrative renaming process. The agency underwent historic restructuring [1].
Seven Talents Transition to Separate Agency Contracts
Despite the conclusion of group activities on September 30, none of the seven members are departing Starto Entertainment. Company leadership verified that Daiki Shigeoka, Akito Kiriyama, Junta Nakama, Tomohiro Kamiyama, Ryusei Fujii, Takahiro Hamada, and Nozomu Kotaki will all remain under official contract. Management stressed that their organizational relationship with each performer remains firmly intact. All seven members stay signed [3].
Beginning Thursday, October 1, 2026, every performer will pursue career milestones as an autonomous solo talent supported by agency management. Starto Entertainment confirmed that it will continue providing full operational infrastructure for each artist’s individual ventures across acting, broadcasting, and personal projects. Agency staff will facilitate their respective transitions into specialized media roles. Solo activities commence on October 1 [3].
By transforming unit contracts into distinct personal representations, Starto Entertainment enables the performers to explore distinct creative directions while preserving their institutional relationship with the firm. The evolution marks a definitive closing chapter for the WEST idol group, yet it secures ongoing industry visibility for the seven talents who defined the sound of WEST. for over a decade. Fans will continue following their respective journeys through solo theater productions, television dramas, and broadcast hosting assignments [3].
