Authorities halted a Pokémon 30th-anniversary celebration in Seoul's Seongsu-dong district on May 1, 2024, after a massive crowd surge created safety risks [1].

The incident highlights the volatility of high-demand collectibles and the challenges of managing large-scale urban events during public holidays. The disruption occurred on Labor Day, a national holiday in South Korea, which contributed to the high volume of attendees [1].

The event was designed to celebrate three decades of the franchise, but the atmosphere shifted when organizers began a giveaway of the rare “잉어킹” (Koi King) card [1]. According to reports, the crowd size grew rapidly throughout the morning. By 10 a.m., approximately 26,000 people had gathered at the site [1]. By noon, that number had surged to an estimated 40,000 people [1].

The density of the crowd led to significant traffic and pedestrian congestion. Local police and fire services were deployed to intervene and eventually shut down the festivities to prevent injuries [1].

Park Yongjin, a participant at the event, described a chaotic scene near the Seongsu Station Exit 4. He said some people were lying on the ground and the crowd blocked a lane of the road, preventing cars from passing for 30 minutes to an hour [1].

Emergency responders acted to clear the area as the surge made it impossible to maintain safety protocols. The event was stopped entirely to ensure the safety of the thousands of fans who had converged on the district [1].

“The crowd size grew rapidly... by noon, that number had surged to an estimated 40,000 people.”

The shutdown of the Seongsu-dong event underscores the 'collector's panic' often associated with limited-edition merchandise. When rare items like the Koi King card are offered, the resulting crowd dynamics can quickly exceed the capacity of urban infrastructure, transforming a marketing event into a public safety hazard that requires emergency intervention.
