Pokémon Mega Festa 2026 Seoul: Complete Seongsu & Seoul Forest Guide

Pokémon Mega Festa 2026 has turned Seoul's Seongdong-gu — Seongsu and the adjacent Seoul Forest — into the world's biggest Pokémon playground. Running from May 1 through June 21, 2026, the franchise's official 30th-anniversary celebration is the largest Pokémon event ever held outside Japan: three flagship pop-ups, a forest takeover at Seoul Forest, a Pokémon GO stamp rally winding through Seongsu's alleyways, a Magikarp marathon along the Han River, and the Pokémon Sports Day finals at COEX.

If you only have a day in Seoul, you can still cover the three free anchor pop-ups in a single afternoon — they're all within a 15-minute walk of Seongsu Station (Line 2) or Seoul Forest Station (Suin-Bundang). This guide walks you through every venue, the exact subway exits, the things you'll actually want to buy, and — critically — how to avoid the four-figure crowds that shut down opening day.

The three anchor pop-ups in Seongdong-gu

These are the flagship destinations and the ones almost every traveler will want to combine in a single visit. All three are free to enter, all three sit within 15 minutes of one another, and all three can be tackled in the order below for the most natural walking route from Seoul Forest down into Seongsu's pop-up district.

1. Pokémon Secret Forest at Seoul Forest

The most family-friendly of the trio and the largest, the Pokémon Secret Forest spreads across roughly 2,800 m² of Seoul Forest's Ginkgo Tree path. Following a marked 'Secret Trail', visitors discover 30 life-sized Pokémon sculptures hidden among the trees, including 'Pikachu's Camping Village', the atmospheric 'Pikachu Forest', and a paid photo booth that adds the official 30th-anniversary frame to your shot.

Because it sits inside the 2026 Seoul International Garden Show, the outdoor exhibit is free — no ticket required to enter Seoul Forest itself, and most of the Pokémon installations can be enjoyed without queuing. There's also a smaller on-site Pokémon Game Center and store for limited goods.

Hours: 12:00–19:00 daily until June 21. Subway: Seoul Forest Station (Suin-Bundang Line) Exit 4, then a 5-minute walk along the park's main path.

Pro tip: Aim for a weekday around 1 PM. Saturdays after 3 PM the trail is almost shoulder-to-shoulder, and the wait at the Pikachu Camping Village photo spot can hit 30+ minutes.

2. Metamon (Ditto) Playground

If the Secret Forest is the picnic, Metamon Playground is the rave. The entire side street at 9 Seongsui-ro 7-ga-gil is painted in Ditto's signature purple, with giant Ditto sculptures lounging across benches, walls, and shopfronts — the result is one of the most photogenic pop-up spaces Seoul has produced in years.

The two-story interior is split between a pop-art retail floor — featuring limited goods tied to the new Pokopia game line and the now-infamous 'Pale Pikachu' plush that has been reselling for over 140,000 KRW since opening day — and a calmer, record-shop-styled second floor dedicated to the Pokémon Trading Card Game, with display walls, demo tables, and a quieter space for cracking booster packs.

Tucked into the back of the ground floor is a small Ditto Cafe serving takeaway drinks and soft-serve in the playground's purple palette — the perfect after-queue reward.

Hours: 10:00–21:00 daily until June 21. Subway: Seongsu Station (Line 2) Exit 3, 4-minute walk. Entry is free but you must register on the on-site QR waitlist and wait for a notification before entering.

3. Pokémon 30th Anniversary Party Pop-up at Olive Young N Seongsu

The most central and crowd-friendly of the three, the 30th Anniversary Party Pop-up takes over Trend Pot, the rotating pop-up space inside Olive Young N Seongsu — Olive Young's flagship five-floor concept store, just 100 metres from Seongsu Station Exit 4. The whole space is dressed as a giant birthday party: oversized fondant-cake photo backdrops, balloon walls, ribbon ceilings, and a coloring corner for younger fans.

The merchandise is the headline. The exclusive 'Birthday Party Edition' line styles Pikachu and friends with cakes, ribbons and confetti — magnets, sliding pin badges, deco stickers, emblem keyrings, and plush greeting-card sets, mostly limited to 2–3 per customer. The marquee item is the 'Pikapika! Pikachu' commemorative plush, a recreation of early-era chubby Pikachu carrying the official 30th-anniversary tag — capped at one per person and frequently sold out within hours of opening on weekends.

Hours: 10:00–22:00 daily until May 31 (final day closes at 18:00). Entry is free, and as a bonus you get four floors of Korea's largest K-beauty selection to browse upstairs.

Beyond the pop-ups: three more Pokémon Mega Festa 2026 events

If you have more than a day in Seoul, three additional Pokémon Mega Festa events are worth working into your itinerary.

Pokémon GO Seoul Stamp Rally (May 1 – May 31)

An outdoor city-wide PokéStop hunt run jointly by Pokémon Korea and Niantic. Open the Pokémon GO app inside the marked Seongsu zone, spin designated PokéStops to collect digital stamps, and earn special encounters and the limited-time Magikarp promo card that famously triggered the May-1 crowd surge. Active 10:00–20:00 daily. You don't need a separate ticket — just the app on your phone.

Pokémon RUN 2026 (May 5 only)

Held on Children's Day at Ttukseom Hangang Park (a 15-minute walk south of Seongsu), this is the world's first Magikarp-themed marathon. Around 5,000 registered runners 'become' Magikarp as they race along the Han River. Registration was a paid pre-event in March — you can't sign up on the day, but you can absolutely show up to the riverside finish line area to watch the Magikarp parade.

Pokémon Sports Day 2026 (May 24 – May 25)

A two-day finale at COEX Hall C in Samseong-dong, Gangnam. Free general admission gets you into the Pokémon Trainers Cup 2026 finals, the Korean Pokémon TCG League 2026 finals, a 30th-anniversary exhibition, official merchandise booths, and stage events. Subway: Samseong Station (Line 2) Exit 5 or 6 — about 20 minutes from Seongsu by metro.

⚠️ Crowd safety & how to visit without stress

On opening day (May 1), an estimated 40,000 people flooded the Seongsu pop-up district hunting the rare Magikarp promo card from the Pokémon GO Stamp Rally. Pokémon Korea was forced to temporarily halt the rally and pop-up admission for several hours due to safety concerns, and major Korean outlets (Kyunghyang, Seoul Economic Daily) covered it widely. Things have stabilized, but the lesson is real: this is not a relaxed weekend stroll.

• Visit on a weekday morning if at all possible. Tuesday–Thursday between 10:00 and 13:00 is the calmest window across all three pop-ups.
• Saturday afternoon is the worst time to come. Combined Pokémon GO foot traffic and pop-up queues can mean 60–90 minute waits.
• Use the subway — Line 2 only. Taxis get stuck for 20+ minutes in pop-up traffic. Seongsu Station (Line 2) handles all three Seongsu venues; Seoul Forest Station (Suin-Bundang) is for the Secret Forest.
• Register the QR queue immediately on arrival at Metamon Playground — your notification can arrive 30 to 90 minutes later, and you can use that time to walk to another venue.
• Have your passport on you. The 30th Anniversary Pop-up store accepts international cards but tax-free purchases require ID.

Recommended routes for foreign tourists

Half-day (3–4 hours) — Seongsu pop-up sprint

Best if you only have one afternoon and want the iconic photos. Start: Seongsu Station Exit 4 → 30th Anniversary Party Pop-up at Olive Young N → walk 5 min → Metamon Playground (register the QR queue first, then explore the street art) → Ditto Cafe takeaway → end with K-beauty shopping back at Olive Young N.

Full day (6–8 hours) — Seongdong Pokémon course

Best for fans who want all three flagships. Start: Seoul Forest Station Exit 4 → Pokémon Secret Forest (90 minutes) → walk 15 min south or take Line 2 one stop → Metamon Playground (60 minutes including queue) → 5-min walk → 30th Anniversary Party Pop-up (60 minutes) → optional Pokémon GO Stamp Rally on the walk back → dinner in Seongsu's pop-up alleys.

Family with kids (5 hours, low-stress)

Best for travelers with strollers or younger kids. Start: Seoul Forest Station Exit 4 → picnic + Pokémon Secret Forest at 12:00 (least crowded entry) → lunch in Seoul Forest → take Line 2 from Ttukseom Park Station to Seongsu (one stop) → 30th Anniversary Pop-up coloring corner → skip Metamon Playground if the queue is over 60 minutes.

Practical tips

• Free entry everywhere. The only paid Mega Festa events are Pokémon RUN (which is closed-registration anyway) and the optional photo booths at the Secret Forest.
• Limited goods sell out fast. The Pikapika Pikachu plush, Pokopia line items, and Magikarp promo cards are typically gone within hours on weekends. Restock schedules are posted only on Pokémon Korea's official Instagram (@pokemon_korea_official).
• Card payment works everywhere. Olive Young N and the Pokémon stores accept Visa, Mastercard, JCB and AMEX. Apple Pay works at most stores.
• English signage is partial. Olive Young N has full English signage; the Metamon Playground store has Korean and Japanese product cards. Google Lens or Papago is genuinely useful.
• Combine with Seongsu's other pop-ups. New beauty and fashion pop-ups open in Seongsu every week. See our weekly roundup: Must-Visit Pop-ups in Seongsu This Week.
