ATEEZ and LINE FRIENDS are bringing MIGHTEEZ, their collaborative character project, back to Shibuya for a third run: MIGHTEEZ Rock The Stage POP-UP. It runs from September 18 to September 27, 2026 at LINE FRIENDS SQUARE SHIBUYA.
If you are flying in for this, the one thing to get right is the opening day. September 18 is reservation-only, so this guide focuses on when you can actually get in and how the entry works.
Opening day, Friday, September 18, is reservation-only, and the slots may already be taken. If you do not have a reservation, plan to visit from Saturday, September 19 onward. A weekday afternoon is your best bet for shorter lines.

How to get in: reservation-only Sep 18, walk-in from Sep 19
The trap is the first day: Friday, September 18 is reservation-only, so you cannot enter that day without a reservation. The release does not spell out how or when reservations open; it points to the official LINE FRIENDS announcement page for the details.
Reservations opened before the run, so by the time this article goes live there may be no slots left. If you are set on going on September 18, check the official page first to see whether any reservation spots remain. Even if you cannot get one, you can buy the same merchandise during the walk-in days.
For a sure thing, build your plan around walk-in entry from Saturday, September 19. No reservation is needed on those days, but staff may limit entry when the store gets busy, which means you may have to queue outside. Weekends and the first hour after opening draw the longest queues, so aim for a weekday afternoon if you want to keep the wait short.
Getting to LINE FRIENDS SQUARE SHIBUYA
The venue, LINE FRIENDS SQUARE SHIBUYA, is about a six-minute walk from Shibuya Station, up toward Koen-dori (Park Street). The Rock The Stage pop-up is on the basement floor (B1F). Previous editions were held on different floors, so follow the signs for the third pop-up once you are inside.
Mid-to-late September in Tokyo is still warm, often around 25–30°C (77–86°F) in the daytime. Since the line forms outside when it's busy, dress for the heat and bring water. If you are still deciding what to pack, see our guide on what to wear in Japan in autumn.
Merchandise and purchase perks: flagship vs. Loft

The lineup includes photocards and store-exclusive goods. Details on featured items such as plushies, including prices, are being announced gradually, so check the official store page before you go.
The purchase perks depend on which store you visit, and it's easy to assume the flagship and Loft work the same way. Check the rule for your store first.
- Shibuya flagship (LINE FRIENDS SQUARE SHIBUYA): for every 5,500 yen (tax included) you spend, you get one random photocard from a set of eight. With a purchase of 5,500 yen or more, you can also buy a reusable bag for 484 yen (tax included).
- Loft stores: with a purchase of 5,500 yen or more, you receive one photocard, but only one per person per transaction, while supplies last.
The flagship also sets purchase limits: up to three of each item per transaction, and up to eight "random photocard sets." If you plan to buy in bulk, budget with those limits in mind so there are no surprises at the register.
If you cannot make it in person, select items go on sale online too. The online launch is 11:00 a.m. on Friday, September 18, at the LINE FRIENDS SQUARE official online store. The collection is also available at select Loft and HMV stores. Event dates vary by location, so check the official channels for the store you plan to visit.
What is MIGHTEEZ?
MIGHTEEZ is a character collaboration between the Korean group ATEEZ and LINE FRIENDS. LINE FRIENDS reinterprets the personalities of ATEEZ's eight members as characters, presented as "eight superpowered fairies."
This is the third MIGHTEEZ pop-up in Shibuya. The first ran in November 2025 and the second in April 2026 at the same venue. The first opened with a reservation-only day followed by walk-in entry, and this edition follows the same pattern.
Before you go
If you are traveling in for this, lock down these three points first.
- Friday, September 18 is reservation-only; go from Saturday, September 19 if you do not have a reservation.
- Store hours during the run are not published, so check the official schedule for your visit day.
- Purchase perks differ between the flagship and Loft; confirm the rule for the store you plan to visit.
