TWICE is getting ready to celebrate a major milestone with ONCE! The group will mark its 11th debut anniversary with a special fan party titled “ONCE UPON A THRI11.”
The event will take place on October 17, 2026, in Seoul, giving a limited number of fans the chance to celebrate the milestone with TWICE in person.
“ONCE UPON A THRI11” will be held across three sessions on October 17, at 2 PM, 4 PM, and 6 PM KST.
Each session will welcome 250 fans, bringing the total number of attendees to just 750 ONCEs. The exact venue will be revealed individually to selected participants and is currently listed as being in the Seoul area.
The event name itself also plays on TWICE’s 11th anniversary, replacing the “LL” in “THRILL” with 11.
While the full program has not been publicly revealed, the intimate fan party is expected to give selected ONCEs a chance to spend a special anniversary moment with TWICE.
With only 250 fans per session, the event will be considerably more intimate than the group's usual concerts and large-scale fan events.
Since making their debut in 2015, TWICE has grown into one of K-pop's biggest girl groups, building a dedicated global fandom through hit songs, albums, world tours, and countless memorable moments with ONCE.
Their 11th anniversary is another milestone in a career that has continued to evolve while maintaining the group's strong connection with fans.
The fan party offers a much smaller and more personal way to celebrate TWICE's anniversary. With only 750 fans able to attend, those selected will have the opportunity to mark 11 years of TWICE in an especially intimate setting.
At the same time, the limited capacity has led to disappointment among some fans, particularly given the size of TWICE's global fandom.
TWICE's “ONCE UPON A THRI11” will bring the group and 750 lucky ONCEs together on October 17 for a special 11th anniversary celebration.
While only a small number of fans can attend in person, the milestone is still another chance to celebrate everything TWICE and ONCE have shared over the past 11 years. Here's to another year of memories with TWICE! 🍭
