The short answer: For Seongsu pop-up stores in October 2026, check your travel dates first: TWS’s TWIMI finishes October 4, ENHYPEN’s SPOOKY ENCHIN October 9, and 10MONTH October 11. T Factory’s Emotion Lab continues through November 15, making it the later-October option in this selection.
Schedule and entry rules rechecked September 27, 2026, Korea time. This is an early selection based on organiser announcements, not a complete October calendar or a report of personal visits. All dates are in 2026.
Which events fit your October dates?
| Event | Announced dates | Hours (KST) | Plan around |
|---|---|---|---|
| TWS: TWIMI : 42 Forest | Sep 28–Oct 4 | 10:30–20:30 | Weverse reservation |
| ENHYPEN: SPOOKY ENCHIN | Sep 29–Oct 9 | 11:00–20:00 | Weverse reservation |
| 10MONTH | Through Oct 11 | Check brand notice | Styling session booked separately |
| T Factory: Emotion Lab | Sep 19–Nov 15 | Check venue notice | Free scent activity; paid colour activity |
For October 1–4, all four fall within their announced dates. From October 5, remove TWIMI; from October 10, remove SPOOKY ENCHIN. After October 11, only Emotion Lab remains on this shortlist. That does not mean there are no other Seongsu events later in the month.
TWS: visiting before October 4?
Map address: 서울 성동구 서울숲2길 42. Search for 투위미 팝업 or use the street address in Naver Map.
The official TWIMI visitor notice lists September 28–October 4, 10:30–20:30. The announced reservation opening was September 23 at 13:00 KST through Weverse. Check the booking page for remaining slots; an opening date is not proof of current availability. Each account can book once, and one reservation admits one person.
Bring the entry QR on your logged-in app or reservation webpage, not a screenshot. The notice allows up to one hour inside and says arrivals more than 20 minutes late are treated as no-shows. It also says staff may admit unreserved visitors depending on conditions; that is a possible fallback, not a guaranteed walk-in ticket.
ENHYPEN: what matters for SPOOKY ENCHIN?
Map address: 해소, 서울 성동구 성수이로24길 31 — HAESO.
The official English visitor guide gives September 29–October 9, 11:00–20:00. This is the ENHYPEN official-character pop-up; do not confuse its dates or address with the TWS event.
Use the reservation link in that notice. Each account may reserve one time slot, and entry requires the live reservation QR rather than a saved image. If a session is full, cancellations may reopen places. Allow up to 30 minutes inside, compared with TWIMI’s one-hour limit. Arriving 20 minutes late means no entry, and re-entry is not allowed. A confirmed slot does not guarantee merchandise stock. The notice lists card, Samsung Pay and Apple Pay for purchases, but not cash; it also warns that some cards may be declined.
10MONTH: shopping rather than character merchandise?
Map address: 서울 성동구 연무장11길 11 — 텐먼스 성수 팝업.
10MONTH is the clothing option here. Its September 14 organiser announcement confirms the pop-up runs until October 11 and describes clothing try-ons, one-to-one styling and complimentary length alterations for qualifying purchased trousers. The brand’s venue announcement supplies the address.
The styling programme uses a separate reservation event through the brand’s Instagram. A visit to browse is not a styling appointment. If alterations are the reason you are buying, ask when you can collect the finished trousers before paying—especially if your flight home is close.
Emotion Lab: visiting later in October?
Map address: 서울 성동구 연무장1길 7-1 — T팩토리 성수. The official T world venue listing confirms this address. Its store hours are not a guarantee that every exhibition session runs for the same hours. This is a temporary brand experience exhibition, rather than a character-merchandise shop.
SK Telecom’s September 18 announcement gives September 19–November 15. The first-floor Scent of Emotion activity makes a personalised perfume and is free regardless of mobile carrier. The basement Color of Emotion activity costs ₩20,000 per person, or ₩16,000 for eligible SKT customers. Do not read “free perfume experience” as meaning every activity is free.
Check the official T Factory site for your visit date’s hours and participation arrangements before building the day around a session. The published event dates are not a live availability check.
Can two people enter on one reservation?
For both TWIMI and SPOOKY ENCHIN, one reservation admits one person. If you are visiting as a pair, each person needs their own reservation. Check both confirmations before making the trip; do not assume one booking includes a guest.
How should you plan the stops?
Choose the event you would be disappointed to miss, secure any required reservation, and then add one flexible stop. Save each Korean address separately: the two music-group events are not in the same building. Compare the addresses in Naver Map after fixing your appointment rather than treating a list of four events as a timed walking itinerary.
If you are leaving Korea that day, set your airport departure plan before filling the afternoon. Our before-flight planning guide and airport luggage-storage guide cover different parts of that decision. For a trip spanning both months, use the September Seongsu calendar only for its stated dates—not as an October list.
Do foreign visitors need a Korean phone number?
The two Weverse notices require an account and a reservation QR. We have not tested their complete booking flows with a foreign phone number, so this guide does not promise that every account can complete every step. Open the official booking link before travelling to the venue and check that you can actually obtain a reservation, not merely view the announcement.
Does an event on this list guarantee entry or gifts?
No. Dates show when the organiser plans to operate, not whether a specific session has space. Treat merchandise, gifts and admission as separate questions; a reservation is not a stock reservation.
Is this the full October schedule?
No. These are four announced options with schedules rechecked on September 27. An early-month closing date matters more than a headline saying “October pop-ups.” Reopen the organiser’s notice before your visit, particularly if you saved this guide several weeks earlier.
