back number KINTEX Concert Guide — Ended Sept 13, Hall 9 Entry & GTX-A Return Routes

The Japanese three-piece back number held their first-ever solo shows in Korea (Grateful Yesterdays Tour 2026) on September 12 (Sat) and 13 (Sun), 2026 at KINTEX Exhibition Center 2, Hall 9, with both nights starting at 18:00. Comic World 336 ran the same weekend at Exhibition Center 1 (Halls 4–5). The Hall 9 floor layout, baggage storage, and GTX-A return routes below still apply to future concerts in this hall.

Note: These concerts took place on September 12–13, 2026; the times below are what was announced beforehand. For upcoming KINTEX concerts, see the guides for Doh Kyung-soo, LANY Live in Seoul, 5SOS KINTEX, and the KINTEX Venue Hub.

Hall 9 is a flat exhibition hall, not an arena#

This is the detail that catches first-timers out. Hall 9 is an exhibition floor with no raked seating — the ground is level, and the stage is what gives you sightline, not the slope of the room. Two consequences:

• In the standing zone, your queue number is your view. There is no tier of seats to fall back on; where you land in the pit is decided at the lineup, hours before the doors open.
• In the seated sections, being tall in front of you matters more than it would in an arena. If sightlines are your priority over proximity, a seat further back but higher on the temporary staging is usually the better trade.

If you want to see roughly what your section will look at, the seat distance simulator for KINTEX Hall 9 and Hall 10 draws this room at its official size with a representative end-stage plan. On a flat floor the head directly in front of you matters as much as the distance, so read the blockage line as well as the metres.

Two nights, and how to pick#

Both performances run the same 18:00 start and an approximate 120～150 minute set.

	September 12 (Sat)	September 13 (Sun)
Show start	18:00	18:00
Expected finish	approx. 20:00～20:30	approx. 20:00～20:30
Getting home	Full Saturday service; the easier night if you are staying out	Sunday services thin out earlier — check your last train before you commit

If you are travelling in from outside Seoul, the Saturday show leaves you more room on the way home.

Your entry timeline#

Time	What happens	What you should be doing
14:00～15:00	Ticket box opens (est.)	Check Yes24’s pickup instructions for your ticket type
15:30	Practical latest arrival at Exhibition Center 2	Leaves margin before the lineup closes
approx. 16:00	Standing lineup, strictly by queue number	Late arrivals lose their number and go to the back
16:30	Gates open	Seated entry flows steadily from here
18:00	Show starts	—

Yes24 issues a final admission notice per performance, and the two nights can differ — read yours rather than assuming the Saturday timings carry over. Ages 12 and above may attend. At the box office you will need the physical passport or Foreigner Registration Card matching your booking; a photo on your phone will not clear it.

Getting there#

Hall 9 is inside Exhibition Center 2, ten minutes on foot from GTX-A KINTEX Station. Both nights start at 18:00, which puts your arrival squarely in the evening road crush — the train is the only route that behaves predictably.
