Seongsu hits a major holiday week. Children's Day falls on Tuesday May 5 (with substitute holiday Wednesday May 6) — Korea's biggest family weekend turns the district into a kid-friendly playground. Pokémon Mega Festa rolls into its second week with three pop-ups still going strong, the Olive Young × Pokémon Concept Store opens its doors, and Saint Laurent Beauty lands at Yeonmujang-gil on May 9.
We've sorted everything into five zones — Children's Day & Pokémon picks, fresh openings, last-call closes, and beauty/fashion drops — so you can plan an efficient route through Seongsu. Five popups close Sunday May 10; budget your week accordingly.
Children's Day (May 5) & Pokémon Mega Festa Picks
Korea's Children's Day on May 5 is a public holiday, and Wednesday May 6 has been designated a substitute day off — so Tuesday and Wednesday are mini-vacation days for Seoul families. These five pop-ups go all-in on family fun, with Seongsu basically transforming into a Pokémon trail.
1. Olive Young × Pokémon Concept Store — NEW
Korea's biggest beauty retailer collabs with Pokémon for an entire concept store inside Olive Young N Seongsu (the flagship). Expect Pokémon-themed beauty packaging, photo zones, exclusive merchandise, and limited-edition product bundles. The 1F Trend Fountain zone is fully decked out — a must for K-beauty fans and Pokémon collectors alike.
Open May 1–31, daily 10 AM–10 PM. Free entry. From Seongsu Station (Line 2) Exit 3, 6-minute walk along Yeonmujang-gil. Tip: Arrive before 11 AM on weekdays — exclusive items sell out fast on Children's Day weekend.

Practical Tips
- Children's Day = busiest weekend. Tuesday May 5 and Wednesday May 6 are public holidays. Expect 2–3× normal foot traffic, especially at Pokémon and Teenieping spots.
- Plan Sunday May 10 carefully. Five popups (BYD, Soonhari, Ploom, Find the Mattress, THE GATHERING) all close or run only that day. Start early.
- Beauty cluster route: Olive Young × Pokémon → FEEV at Musinsa → isoi → Mude → Saint Laurent (when open). All within Yeonmujang-gil, walkable in 20 minutes total.
- Subway: Seongsu Station (Line 2), Exit 3 or Exit 4 covers all 15 popups. Seoul Forest Station (Bundang Line) Exit 4 for Pokémon Secret Forest.
- Free entry on every popup, but bring ID for adult-only spots (Soonhari, Ploom).
