I.O.I is making their highly anticipated return for their 10th anniversary with both a comeback and tour in 2026.

The group announced their "LOOP" tour will visit three cities: Seoul, Bangkok, and Hong Kong during May and June 2026. The tour follows their planned May comeback, marking a decade since the group first debuted through Mnet's "Produce 101" in 2016.

Nine members are confirmed to participate in the anniversary activities, including Jeon Somi. The original group consisted of 11 members who promoted together for less than a year before disbanding in early 2017 to return to their respective agencies.

Since their disbandment, the members have pursued various career paths. Somi has established herself as a successful solo artist under The Black Label, while other members have joined different groups or continued as soloists. The reunion represents a rare opportunity for fans to see the group perform together again.

I.O.I's original run was brief but impactful. Their debut single "Dream Girls" and follow-up tracks like "Whatta Man" and "Very Very Very" became major hits, cementing their place in K-pop history despite their short promotional period.

The "LOOP" tour name suggests the cyclical nature of their return, bringing the story full circle after nearly a decade apart. Seoul will likely serve as the tour's home base, while Bangkok and Hong Kong represent their continued popularity across Asia.

Specific dates and venues for the tour stops haven't been announced yet, but fans can expect more details as the May comeback approaches. The reunion comes at a time when temporary group reunions have become more common in K-pop, though few carry the nostalgic weight of I.O.I's return.

With their anniversary celebration combining both new music and live performances, I.O.I is giving fans the comprehensive reunion they've been hoping for since the group's early disbandment.
