The Pokémon 30th Anniversary Party Pop-up takes over Trend Pot — the rotating popup space inside Olive Young N Seongsu, the brand's flagship five-floor concept store on Yeonmujang 7-gil — for the entire month of May 2026. As one of the central stores of the citywide Pokémon Mega Festa 2026 celebration, it is dressed top-to-bottom as a giant birthday party for the franchise: oversized fondant-cake photo backdrops, ribbon-streamer ceilings, balloon walls, and a kid-friendly coloring corner where younger fans can fill in 30th-anniversary illustrations.

Find travel buddiesMerchandise is the headline. The exclusive 'Birthday Party Edition' line revolves around Pikachu and friends styled with cakes, ribbons and confetti — magnet sets, sliding pin badges, deco stickers, emblem keyrings and plush greeting-card sets, most limited to 2–3 per customer. The marquee item is the 'Pikapika! Pikachu' commemorative plush — a recreation of early-era chubby Pikachu carrying an official 30th-anniversary tag, and so coveted that purchase is hard-capped at one per person and frequently sells out within hours of opening.
Location-wise it could not be easier: a 100-metre walk from Seongsu Station Line 2 Exit 4. Hours are 10:00–22:00 every day from May 1 to May 31, 2026 (last day closes at 18:00). Entry to the pop-up is free, but expect long queues on weekends, especially since Olive Young N's other floors offer Korea's biggest K-beauty selection — making it a natural pairing with the Metamon Playground (5 minutes away) and the Pokémon Secret Forest in Seoul Forest for a one-day Seongdong Pokémon course.
