What this is
THE IDOLMASTER SideM 11th STAGE ～EVER EVER＠FTER～ is a major two-day live concert event celebrating the 11th anniversary stage of THE IDOLMASTER SideM, the male idol branch of Bandai Namco's long-running IDOLMASTER multimedia franchise. SideM focuses on male idols across various units and has built a passionate fanbase through its mobile game, anime, and live performances since its launch in 2014. These numbered STAGE events are landmark occasions in the SideM calendar, bringing together voice actors who perform as their in-game idol characters in full concert format with elaborate staging, costumes, and fan participation. The 2026 edition marks the 11th such milestone event, taking place across two days at the large-scale TOYOTA ARENA TOKYO in September 2026.
Who should go
This event is ideal for dedicated fans of THE IDOLMASTER SideM franchise, whether you follow the mobile game, anime, or previous live events. Attendees can expect an energetic, emotionally charged atmosphere with coordinated light stick cheering, call-and-response audience participation, and passionate fan communities. Casual anime fans curious about idol live culture will also find it a fascinating and immersive experience. Book your preferred day early as two-day tickets and individual day tickets typically sell out quickly for major SideM STAGE events.
Good to know
Tickets will most likely be distributed via an official fan club priority lottery through Bandai Namco Entertainment's membership service before general sales open on eplus.jp or pia.jp — both platforms accept foreign credit cards, and convenience store pickup (combini) at Lawson is the most reliable collection method for visitors without a Japanese delivery address. TOYOTA ARENA TOKYO is a large indoor arena venue capable of hosting several thousand attendees, suitable for major idol live events with full stage production. Merchandise sales typically begin several hours before doors open and lines can stretch very long — arriving early is strongly recommended if purchasing goods. The venue will almost certainly enforce a no-photography and no-video-recording policy during the performance, which is standard for IDOLMASTER live events. Bring cash for merchandise purchases as card payment is not always available at goods booths.
