The Pokémon 30th Anniversary Party is the key Seongsu pop-up inside Pokémon Mega Festa 2026, the wider Seoul anniversary project running from May 1 to June 21, 2026. The party pop-up itself is held at Trendpot by Olive Young N Seongsu from May 1 to May 31, 2026, with regular operating hours from 10:00 to 22:00 and an earlier 18:00 closing time on the final day. 1
For anyone planning a visit on or after May 29, 2026, the practical point is that the confirmed event window is almost over. The official Pokémon Korea page lists the Pokémon 30th Anniversary Party period as May 1 to May 31, 2026, but the available source material does not provide a reservation method, admission price, refund rule, queue policy, or restock schedule. 2
Pokémon 30th Anniversary Party: What Is Confirmed

The official venue is Trendpot by Olive Young N Seongsu. Pokémon Korea places the party within the Seongsu-area program for Pokémon Mega Festa 2026, alongside other locations in the broader Seoul project, including Seoul Forest, Seongsu, and COEX. 1
The Seongsu event is described as a 30th-anniversary party-themed pop-up store and exhibition space. Electronics Times reported that CJ Olive Young’s Pokémon collaboration runs from May 1 to May 30, 2026, with 61 participating brands and about 230 limited products, and that Olive Young N Seongsu is operated as the Pokémon “30th Anniversary Party” pop-up store and exhibition space. 3
Confirmed or reported visitor elements include a coloring zone, photo zone, capsule-toy-style limited product sales area, Pikachu-shaped desserts, and a floor-by-floor stamp rally. 3 Game Chosun also reported on-site features and goods including a photo zone, capsule toy zone, 30th anniversary logo sticker collection, magnet set, and pin badges. 4
Those details are useful for planning, but they should not be read as a guarantee that every item will be available at every time. The source material confirms the event concept, venue, period, operating hours, and reported activity areas, but it does not state inventory quantities, purchase limits, waiting-time estimates, payment methods, or whether specific products are restocked after selling out.
How to Plan a Visit in Seongsu
Because this is one of the major Seongsu Pop-Ups connected to Pokémon Mega Festa 2026, visitors should plan around both the pop-up and nearby anniversary programming. The wider project includes major programs such as Pokémon Secret Forest, Ditto Playground, Pokémon 30th Anniversary Party, Pokémon Run 2026, and Pokémon Sports Day 2026. 5
For Seongsu specifically, the nearby Ditto Playground may affect crowd movement. Game Chosun reported that the Seongsu-dong Ditto Playground includes an exhibition and store, Ditto cafe, Pokémon Card Game showroom, and DJ Pikachu photo spot. 4 That means visitors going only to the 30th Anniversary Party may still encounter foot traffic from people moving between multiple Pokémon-related destinations in the same district.
A practical visit plan should start with the confirmed hours. On ordinary operating days, the party is listed for 10:00 to 22:00. On May 31, 2026, the final day, the official schedule says the event closes at 18:00. 1 Since no official ticketing or booking process is included in the supplied source material, visitors should not assume that a reservation option exists based on these sources alone.
It is also worth separating the Olive Young collaboration period from the Pokémon Korea party period. Electronics Times reported the Olive Young X Pokémon IP collaboration from May 1 to May 30, 2026, while Pokémon Korea’s official event listing gives the Pokémon 30th Anniversary Party period as May 1 to May 31, 2026. 3 2 For planning purposes, the official party page is the clearest source for the pop-up period, while the collaboration article helps explain the scale and product context.
Crowd and Safety Notes
The strongest caution in the available sources concerns opening-day crowding. Segye Ilbo reported that on May 1, 2026, the Labor Day holiday, large crowds gathered around the Seongsu-dong Pokémon Mega Festa area, and the event was eventually halted for safety reasons. 6
The same report said safety concern reports had been received from the morning, about 90 police personnel were deployed near Seoul Forest event booths and nearby areas, and Seoul city estimates placed the Seongsu Cafe Street crowd at 26,000 around 10:00 and about 40,000 around noon. Organizers reportedly stopped the event around noon at the request of Seoul city and others. 6
That report does not mean every later operating day had the same conditions, but it does show why visitors should leave extra time, avoid assuming quick entry, and consider crowd conditions when moving between Seongsu-area Pokémon sites. Families, groups, and visitors trying to buy limited goods should be especially cautious about time planning because the source material does not include live queue updates or product availability details.
