BIGBANG is celebrating its 20th anniversary with an immersive media exhibition in Seoul titled BIGBANG 20TH ANNIVERSARY MEDIA EXHIBITION “COSMOS.”
This is not a typical K-pop pop-up store or photo exhibition.
The exhibition uses a long underground space beneath Seoul Plaza, between City Hall Station and Euljiro 1-ga Station, and combines BIGBANG’s music and videos with media art, projection mapping, holograms, VR, and other immersive content.
For international visitors, however, there is one thing to check before anything else:
Tickets.
BIGBANG COSMOS is operated through advance reservation via NAVER Booking rather than simple walk-in ticket sales.
For foreign visitors who are unfamiliar with Korea’s reservation system, issues such as NAVER account access, passport verification, overseas credit cards, and payment approval can be just as important as the exhibition itself.
This guide focuses on how foreign visitors can book BIGBANG COSMOS tickets, what to prepare before visiting, and how to find the venue without getting lost.

What Is BIGBANG COSMOS Seoul 2026?
The official exhibition title is:
BIGBANG 20TH ANNIVERSARY MEDIA EXHIBITION “COSMOS”
It is an immersive media exhibition created to celebrate the 20th anniversary of BIGBANG’s debut.
Rather than simply displaying photographs and memorabilia in one room, the exhibition is designed as a long, walk-through experience where visitors encounter BIGBANG’s music, videos, and media content throughout the space.
The exhibition includes:
n other words, you are not looking for a large standalone exhibition building. You are entering an underground cultural space in central Seoul.
How Foreign Visitors Can Book BIGBANG COSMOS Tickets
This is the most important section for international BIGBANG fans.
Do not plan to arrive at the venue first and figure out the ticket situation later.
BIGBANG COSMOS uses NAVER Booking, and visitors should reserve their preferred date and entry time in advance.
NO WALK-IN TICKET.
BOOK BEFORE YOU GO.
1. Open the official BIGBANG COSMOS NAVER Booking page.
2. Log in with a NAVER account.
3. Select your preferred date.
4. Choose an available entry time.
5. Select the number of visitors.
6. Confirm the reservation information.
7. Complete identity verification if required.
8. Complete payment.
9. Check that the reservation appears as completed in your NAVER booking history.
Can Foreigners Use NAVER Booking?
NAVER provides reservation functions for non-resident foreign visitors traveling in Korea.
For services that support foreign reservations, language assistance may be available in English, Japanese, and Simplified Chinese through NAVER’s translation system.
For prepaid reservations, overseas-issued credit cards may also be supported when the individual business has enabled foreign reservations and international card payments.
This means that not having a Korean mobile phone number does not automatically make every NAVER Booking service unavailable to foreign visitors.
However, there is an important limitation.
Foreign visitor support on NAVER does not mean that every booking product works exactly the same way.
The actual booking process can vary depending on:
The venue’s reservation settings
The payment method
The user’s NAVER account status
Identity verification requirements
The card issuer
The individual reservation product
NAVER Account and Passport Verification
PASSPORT VERIFICATION
Foreign visitors sometimes experience difficulty with Korean online services because they do not have a Korean mobile phone number for identity verification.
NAVER provides passport-based identity verification for some services used by foreign visitors.
If verification is required, users may be asked to photograph a valid passport and complete a face scan so that NAVER can confirm that the user matches the passport holder.
This does not mean that every foreign visitor must complete passport verification before booking BIGBANG COSMOS.
It should be understood as an available verification method if additional identity confirmation is required during the booking process.
For this reason, it is better to install the NAVER app, create or prepare your NAVER account, and confirm that you can log in before arriving at the exhibition.
Do not wait until you are standing outside the venue to set up your account for the first time.
Can You Pay with an Overseas Credit Card?
CAN I PAY WITH AN OVERSEAS CARD?
This is one of the most practical concerns for foreign visitors.
NAVER Booking can support overseas-issued credit cards when the reservation provider has enabled foreign visitor reservations and international card payment for prepaid products.
However, “international cards are supported” does not mean that every overseas card will always be approved.
Payment may still fail because of:
The issuing bank’s security policy
International online payment restrictions
Additional authentication
3D Secure verification
Card issuer fraud prevention
Country-specific payment restrictions
For this reason, BIGBANG COSMOS should not be treated as a reservation that you can safely leave until after arriving in Seoul.
If your travel dates are already confirmed, it is better to open the official booking page in advance, check available time slots, and test whether your own overseas-issued card can complete the payment successfully.
Recommended Booking Order for Foreign Visitors
NAVER account ready
Open the official BIGBANG COSMOS booking page
Choose a date and entry time
Complete passport verification if required
Try overseas card payment
Confirm successful payment
Check the completed reservation in NAVER
Only after these steps are complete should you consider your ticket fully secured.
What If Your Overseas Card Keeps Failing?
IF YOUR CARD DOESN’T WORK
First, check the following:
Is the card enabled for international online purchases?
Has the card issuer blocked overseas transactions?
Does the card require additional security verification?
Can you try another overseas-issued card?
Is there any restriction on your NAVER account?
Is identity verification still required?
Does the reservation product support foreign payment?
If you still cannot complete the reservation, you may consider asking a family member or a highly trusted friend in Korea for help.
However, unofficial personal ticket agents found through social media, open chat rooms, or messaging apps are not recommended.
There may be risks involving:
Reservation name mismatches
Excessive service fees
Payment scams
Non-refundable transactions
Communication problems
Cancellation disputes
Problems at the venue if the booking information does not match the visitor
Whenever possible, use the official BIGBANG COSMOS NAVER Booking page directly.
What Should You Prepare on the Day of Your Visit?
After completing your reservation, make sure you can easily open your NAVER booking information on your phone.
It is also a good idea to take a screenshot of your reservation confirmation in case your mobile internet connection is unstable.
If your reservation provides a QR code, barcode, or mobile admission screen, check it before leaving for the venue.
The exact admission method may depend on the instructions shown in your completed reservation, so always read the final visitor information provided by NAVER Booking.
Foreign visitors are also advised to carry their physical passport.
Current official exhibition information does not clearly state that every foreign visitor must show a passport at the entrance.
However, carrying the passport used for your travel is a sensible precaution in case the staff needs to confirm the booking holder’s identity.
If your reservation or NAVER identity verification uses your English passport name, having the matching physical passport with you can help avoid unnecessary problems.
Most importantly, arrive according to your reserved entry time.
BIGBANG COSMOS operates with limited admission by time slot, so it may not work like a conventional museum where visitors can arrive at any time during opening hours.
Arriving a little early gives you time to find the entrance and prepare your booking confirmation.
What Can You See Inside BIGBANG COSMOS?
COSMOS is different from a traditional anniversary exhibition where photographs and memorabilia are simply displayed around one room.
Visitors move through a roughly 335-meter-long underground space while experiencing BIGBANG’s music, videos, and immersive media content.
The exhibition includes:
Media art
IMMERSIVE ZONE
Projection mapping
IMMERSIVE ZONE
Holograms
IMMERSIVE ZONE
VR experiences
IMMERSIVE ZONE
Music and video installations
IMMERSIVE ZONE
Interactive media content
IMMERSIVE ZONE
A total of 11 experience zones are arranged throughout the underground route.
The space itself is part of the attraction.
An old underground area in central Seoul has been transformed using light, sound, video, and digital media while retaining much of its original concrete structure.
As a result, the exhibition feels less like a conventional museum and more like an entire underground environment transformed into a BIGBANG media experience.
For long-time BIGBANG fans, the emotional appeal may come from experiencing the group’s music while moving through a space designed around 20 years of memories and visual content.
How to Combine BIGBANG COSMOS with a Day in Central Seoul
One of the biggest advantages of BIGBANG COSMOS is its location.
The exhibition is not in a remote area of Seoul.
It is positioned in the heart of the city, between City Hall, Euljiro, and Myeongdong.
That makes it easy for international visitors to combine the exhibition with several major Seoul attractions in one day.
Deoksugung Palace
Deoksugung Palace is located next to City Hall Station and is one of the easiest attractions to combine with a COSMOS visit.
You can explore the palace and walk along the famous Deoksugung Stone Wall Road before or after the exhibition.
Seoul Plaza and Seoul City Hall
Because the exhibition space is located beneath the Seoul Plaza area, these locations are naturally connected to your visit.
They are also convenient starting points for exploring central Seoul on foot.
Myeongdong
Myeongdong is close to Euljiro 1-ga Station and is easy to visit after the exhibition.
It is a practical next stop for:
K-beauty shopping
Korean cosmetics
Fashion
Restaurants
Cafes
Souvenir shopping
A simple day route for foreign visitors could look like this:
Final Take · BIGBANG COSMOS SEOUL 2026
BIGBANG COSMOS Seoul 2026 is more than a simple anniversary exhibition celebrating 20 years of BIGBANG.
It transforms a roughly 335-meter-long underground space beneath Seoul Plaza into an immersive environment combining BIGBANG’s music, video, media art, holograms, and VR.
For international fans, however, ticket booking is just as important as the exhibition itself.
The key points are simple.
First:
Do not wait until you arrive at the venue to solve the ticket problem.
Second:
Book through the official BIGBANG COSMOS NAVER Booking page in advance.
Third:
If you plan to use an overseas-issued credit card, check whether your card can successfully complete the payment before traveling to Korea.
Fourth:
If identity verification is required during the booking process, passport-based verification may be available, so keep a valid passport ready.
Fifth:
Use the official reservation system whenever possible and avoid unofficial personal ticket agents found through social media or messaging apps.
If BIGBANG COSMOS is part of your Seoul travel plans, the first thing to secure is not the route to the venue.
It is your ticket.
