NCT 127 THE REDLINE Seoul is set as the opening stop of the group’s fifth tour, officially styled as NCT 127 5TH TOUR ‘NEO CITY : THE REDLINE.’ The Seoul concerts are scheduled for September 18 to 20, 2026 at KSPO DOME, placing the city at the front of the new NCT 127 World Tour schedule. 1
For readers trying to confirm what is already fixed and what still needs to be announced, the key point is simple: the Seoul dates and venue have been named, but detailed ticket reservation information has not yet been released in the official Weverse notice. 1
NCT 127 THE REDLINE Seoul: Confirmed Essentials

The Seoul run is currently the most specific part of the announcement for fans planning around the new tour. The official notice lists Seoul first, followed by Jakarta, Hong Kong, Singapore, Bangkok, and Taipei. 1 NCT 127’s official X account also posted the initial tour schedule, listing Seoul at KSPO DOME for September 18 to 20, 2026, with later dates continuing through January 2, 2027. 2
| Item | Confirmed information |
|---|---|
| Tour title | NCT 127 5TH TOUR ‘NEO CITY : THE REDLINE’ 1 |
| Seoul dates | September 18-20, 2026 1 |
| Seoul venue | KSPO DOME 1 |
| Tour order | Seoul is listed before Jakarta, Hong Kong, Singapore, Bangkok, and Taipei 1 |
| Ticket details | Reservation details and schedules will be announced later 1 |
This makes the Seoul concerts the practical starting point for anyone tracking the tour. The available sources do not provide show times, ticket prices, seating maps, fan club presale rules, or refund terms. Until those details are published through official channels, readers should treat only the dates, venue, and tour title as confirmed.
How the Seoul Shows Fit the 10th-Anniversary Schedule
The Seoul concerts are part of a wider 10th-anniversary year for NCT 127. Yonhap News Agency reported that SM Entertainment said the group will release its seventh full-length album on August 24, 2026, and begin a new tour on September 18 at Seoul’s KSPO Dome. 3 Newspim also reported the same August 24 album date and said the fifth tour opens at Seoul’s KSPO DOME from September 18 to 20. 4
That sequence matters for planning. The album release is scheduled before the Seoul concerts, so the September shows will follow the release of NCT 127’s seventh studio album. The sources do not state a Seoul setlist, whether new album tracks will be performed, or whether the concert production will differ from later overseas stops. Those details remain outside the confirmed information.
Aju Press reported that the seventh full-length album is due August 24 through Virgin Music Group and that the fifth world tour, ‘NEO CITY – THE REDLINE,’ starts with three KSPO Dome concerts in Seoul from September 18 to 20. 5 The same report noted that the tour follows the group’s 2025 ‘NEO CITY – THE MOMENTUM’ run. 5
For fans comparing articles, the tour title appears with slightly different punctuation across sources, including ‘NEO CITY : THE REDLINE’ in the Weverse notice and ‘NEO CITY – THE REDLINE’ in several reports and the official X summary. The safest approach for formal reference is to preserve the styling used by the official channel being cited.
What to Watch Before Booking Travel
The biggest missing item is ticketing. The official Weverse notice says ticket reservation details and schedules will be announced later, so there is no source-backed ticket open date, presale period, general sale time, or price range available from the provided materials. 1
Readers considering travel to Seoul should separate confirmed event information from pending ticket logistics. The confirmed framework is a three-day Seoul concert run at KSPO DOME from September 18 to 20, 2026. The pending information includes ticket platforms, purchase limits, membership benefits, seating categories, accessibility policies, and refund rules.
Newspim reported that additional regions will be announced later through official social media accounts. 4 JTBC, via Daum, also reported that after Seoul the tour is scheduled to visit Jakarta, Hong Kong, Singapore, Bangkok, and Taipei, with more locations to be updated later. 6 For readers outside the listed cities, that means the initial schedule should not be treated as necessarily final.
