Pokémon Mega Festa 2026 is the key Pokémon stop for anyone planning a Seongsu Popup Tour in May 2026. The Seongsu-focused program centers on two official locations: the Pokémon 30th Anniversary Party at Trendpot by Olive Young N Seongsu and Ditto Playground at 9 Seongsui-ro 7ga-gil, both listed by Pokémon Korea as part of the wider Seoul 30th anniversary event. 1
The full Pokémon Mega Festa 2026 period runs from May 1 to June 21, 2026, but the Seongsu programs do not all share the same dates or hours. Visitors should plan by venue rather than assuming every Pokémon Mega Festa activity follows one common schedule. 1
Seongsu Pokémon Mega Festa 2026: Dates and Hours

The most time-sensitive Seongsu stop is the Pokémon 30th Anniversary Party pop-up store. Pokémon Korea lists the venue as Trendpot by Olive Young N Seongsu, with the pop-up running from May 1 to May 31, 2026. Regular operating hours are 10:00 to 22:00, while the final day, May 31, closes earlier at 18:00. 2
For readers checking plans on May 23, 2026, the 30th Anniversary Party is still within its announced operating period, but it has a clearly defined end date. If the visit is planned close to May 31, the earlier final-day closing time matters: the source material supports an 18:00 close on the last day, not the usual 22:00 close. 2
The second major Seongsu location is Ditto Playground at 9 Seongsui-ro 7ga-gil. Pokémon Korea’s official Q&A lists this Seongsu-area venue with operating hours of 10:00 to 21:00. The same Q&A separates it from the 30th Anniversary Party at Trendpot by Olive Young N Seongsu, so it should be treated as its own stop with its own closing time. 1
A practical route can therefore start with Ditto Playground and continue to Trendpot by Olive Young N Seongsu, since the 30th Anniversary Party normally stays open one hour later. The exception is May 31, when the 30th Anniversary Party closes at 18:00. This is only schedule-based guidance; the supplied sources do not provide reservation rules, queue rules, or guaranteed entry details.
What to Expect at the Seongsu Stops
The Pokémon 30th Anniversary Party at Olive Young N Seongsu is tied to the “Olive Young X Pokémon” IP collaboration. ZDNet Korea reported that the collaboration ran from May 1 to May 30, 2026, with Olive Young N Seongsu as the central space, and that the site included a Pokémon 30th anniversary party-themed pop-up store and exhibition area. Reported features included a coloring zone, photo zone, capsule toy zone, and Pikachu desserts. 3
GameMeca also described the Trendpot by Olive Young N Seongsu pop-up store as running until May 31, with photo zones, capsule toy areas, original goods, and venue-limited goods. 4 That gives merchandise-focused visitors a useful baseline: the source material confirms goods and venue-limited items, but it does not provide item names, prices, purchase limits, or restock schedules.
Ditto Playground has a different concept from the Olive Young N Seongsu party pop-up. GameMeca reported that the Seongsu-dong Ditto Playground was designed as a purple Ditto-themed space and included a Ditto cafe, Pokémon Card Game showroom, and DJ Pikachu photo spot. 4 Based on the available facts, this stop is not described only as a shop; it combines themed space design, cafe content, card-game display elements, and photo opportunities.
The wider Pokémon Mega Festa 2026 program extends beyond these two Seongsu stops. ETNews reported that the Seoul-wide 30th anniversary program included Seoul Forest Secret Forest, the Seongsu-dong Ditto Playground, the 30th anniversary party at Trendpot by Olive Young N Seongsu, Pokémon Run, Pokémon Sports Day, and a Pokémon GO Seoul Stamp Rally in the Seongdong-gu area. The same report said the stamp rally was planned for May, with rewards available after collecting stamps from six designated locations. 5
Crowd and Safety Notes Before Visiting
Crowd conditions became an important planning issue on the opening day. Dong-A Ilbo reported that on May 1, 2026, large crowds gathered around Seongsu-dong and Seoul Forest during Pokémon Mega Festa, with Seoul city figures estimating about 40,000 people around Seongsu Cafe Street and about 120,000 people inside Seoul Forest. The report also said police were dispatched because of crowding and safety concerns. 6
The same report said the organizer announced a temporary suspension of the Seoul Stamp Rally event for safety reasons. 6 This point matters because earlier program coverage described the stamp rally as part of the May event plan, but later opening-day coverage reported a safety-related suspension. Visitors should distinguish between the announced program and the later crowd-control update.
For a Seongsu-focused visit, the safest reading of the supplied information is simple: confirm the specific venue and date before going, expect possible crowd management, and do not rely on the stamp rally as the main reason for the trip unless a current official notice confirms its status. The sources provided here do not include live queue times, entry caps, ticketing steps, or refund information.
