It is 4:30 in the morning in Yongsan. The rapper known as RM will not arrive for months. Yet the queue outside the National Museum of Korea has already begun to curl around the building. In fact, it is a ribbon of people in puffer jackets, clutching thermoses. They are not waiting for a concert. Instead, they are waiting for a museum to open at 9:30 a.m. A decade ago, this scene would have been unthinkable. Back then, national museums were where school groups went on rainy Tuesdays. Generally, they were quiet, worthy, and slightly dusty. However, something has shifted. In 2025, the NMK drew roughly 6.5 million visitors. That was a 70 percent jump in a single year. As a result, it leapfrogged the British Museum in London and the Metropolitan Museum of Art in New York. It is now the third most-visited museum on Earth. For foreign investors and hospitality groups, this is not a cultural footnote. Instead, it is a signal. In particular, it shows that the forces powering K-pop, K-drama, and K-beauty have reached the country's oldest institutions. In turn, a state museum has become a genuine commercial and diplomatic asset. The Numbers Behind Korea's National Museum Let us start with the figure that made global headlines. The Art Newspaper released its annual attendance survey in spring 2026. According to that survey, the National Museum of Korea placed third worldwide with 6,507,483 visitors in 2025. Notably, only two institutions ranked higher. The Louvre in Paris topped the list with 9,046,000 visitors, followed by the Vatican Museums with 6,933,822. What makes the ranking remarkable, though, is the company it now keeps. The NMK finished ahead of the British Museum, which came fourth, and the Metropolitan Museum of Art, which placed fifth. These are institutions with centuries of prestige. Indeed, they anchor tourist itineraries around the world. Meanwhile, Seoul's national museum pulled it off in a country still associated with phones and pop stars, rather than porcelain and pagodas. The growth rate is arguably more striking than the ranking. The museum's main venue grew more than 70 percent, from 3.8 million visitors in 2024 to 6.5 million in 2025. For context, that is one of the largest jumps the survey has ever recorded. Moreover, The Art Newspaper described South Korea as showing "the most remarkable growth" among all countries surveyed. The momentum has not slowed, either. In the first quarter of 2026, some 2 million people visited the museum, up 44.8 percent from a year earlier. If that pace holds, the Seoul museum boom could push the NMK toward second place in the next survey. The success went beyond a single building, too. Other Korean museums placed in the global top 100. For instance, the National Museum of Modern and Contemporary Art in Seoul ranked No. 35. Furthermore, the Gyeongju National Museum came in at No. 39. Clearly, this is a nationwide phenomenon, not a one-venue fluke. Why the Seoul Museum Boom Happened Now So why now, and not five years ago? The honest answer is that several forces converged at once. No single explanation covers it. Instead, think of it as a perfect storm. Four separate currents happened to peak in the same window. The Hallyu Halo Effect The first current is the obvious one: the Korean Wave. For two decades, Korean film, music, and television have primed a global audience. As a result, anything labeled "Korean" now feels inherently interesting. Consider the evidence. Bong Joon-ho won the Oscar for Parasite. Then Squid Game topped Netflix in more than 90 countries. Meanwhile, BTS filled stadiums from London to São Paulo. In each case, they were not just exporting entertainment. Rather, they were exporting curiosity. Eventually, that curiosity trickles down to the source material. A fan who discovers Korea through a Joseon-era drama eventually wants to see the real thing. As The Art Newspaper put it, the worldwide fervor for Korean culture is translating directly into museum visits from locals and foreigners alike. Seoulz has tracked the same dynamic across the Korea inbound tourism boom, where record arrivals are reshaping the travel economy. The Lee Kun-hee Collection The second current arrived as a gift so large it required its own logistics operation. In April 2021, the family of the late Samsung chairman Lee Kun-hee donated his private art collection to the Korean state. By any measure, this was no ordinary bequest. The collection comprises more than 23,000 works, reflecting over 70 years of generational collecting. Moreover, it is widely understood to be part of a deal to settle an inheritance tax bill of over 12 trillion won, roughly $8.2 billion. That tax bill is a story in itself. In fact, it ties closely to the broader question of how Korea's chaebol families manage succession. Regardless, the effect on the museum was transformative. Almost all of the 23,000 items went to the National Museum of Korea and the National Museum of Modern and Contemporary Art. In one stroke, an already world-class collection grew far deeper. Crucially, the museum then took the collection abroad. First, a touring exhibition opened at the Smithsonian's National Museum of Asian Art in Washington. From there, it traveled to the Art Institute of Chicago. The Washington show alone attracted about 80,000 visitors. Further stops are planned, too, including a run at the British Museum from September 2026. For audiences who had never set foot in Seoul, this was a first handshake with Korean art history. The MU:DS Merchandise Machine The third current is the one that turns art lovers into dawn queuers. Over the past few years, the museum's foundation reinvented its gift shop. What was once an afterthought became a design-led retail brand called MU:DS. So far, the results have been staggering. In 2025, merchandise and heritage-inspired design products surpassed 40 billion won in annual sales. In particular, cult objects drove the surge, led by a miniature of the 1,400-year-old Pensive Bodhisattva statue. We covered this retail phenomenon in our look at why crowds line up before dawn for museum goods. For now, the key point is structural. Above all, the shop gives casual visitors a reason to return. In addition, it converts foot traffic into revenue. In that sense, the museum has absorbed the same lesson that turned Korea's convenience-store chains into lifestyle destinations. A functional space can also be a retail experience. Free Admission The fourth current is the simplest. It is also the most fragile. Since May 2008, admission to the permanent exhibitions has been free. The National Museum of Korea has offered free entry to its permanent galleries since 2008, though special exhibitions with overseas partners are ticketed. Consider a family of four. Add zero cost. Suddenly, the biggest barrier to a spontaneous visit disappears. Free entry alone cannot explain a 70 percent surge, of course. After all, plenty of free museums stagnate. However, combine it with the other three currents, and it becomes an accelerant. In effect, it lets the Hallyu halo, the Lee Kun-hee draw, and the MU:DS pull convert into actual bodies through the door. No one pauses at a ticket window to reconsider. RM, BTS, and the Ambassador Gambit Do you want a single image of where the museum sees its future? It arrived in June 2026. The museum named RM, leader of BTS, as its first-ever global ambassador. Specifically, the appointment recognized his longstanding interest in Korean traditional culture. For a state institution built on solemn scholarship, choosing a chart-topping rapper as its public face was a bold statement. The choice was not random, though. RM's relationship with the museum stretches back to 2021. Back then, one of his social media posts featuring the Pensive Bodhisattva Miniature quietly boosted a major exhibition. Beyond fandom, he has also backed heritage work with his own money. RM donated 100 million won in both 2021 and 2022 to the Overseas Korean Cultural Heritage Foundation. The funds support the preservation of Korean cultural assets held abroad. For the museum, then, the logic is clear. After all, RM commands a global audience of tens of millions. Many are exactly the young, culturally curious travelers the NMK wants. According to one travel-industry analysis, the appointment connects modern K-pop with centuries-old heritage. Above all, it aims to draw international visitors into Korea's artistic legacy. It is the same soft-power calculus behind the entire BTS economic engine. Notably, RM framed it in personal terms. "I want to do my part so that the beauty and value of our cultural heritage can reach more people," he said. Take the sentiment at face value or not; the payoff is obvious. A single post from RM reaches more potential visitors than any tourism-board campaign. The Ripple Effect Across Korea The rising tide has lifted more than one boat. The NMK sits atop a national museum system. Therefore, its success has pulled attention toward regional institutions that foreign visitors would otherwise never find. Take Gyeongju, for example, the ancient Silla capital. It is often called Korea's "museum without walls." Its national museum landed at No. 39 worldwide, helped by a blockbuster show. The exhibition "Silla Gold Crowns: Power and Prestige" opened in October 2025, bringing together six gold crowns from the ancient Silla Kingdom. Strategically, it was timed to the APEC summit. Remarkably, the show drew nearly 2 million visitors on its own. This matters for anyone planning Korean travel beyond Seoul. Over-tourism now strains hotspots like Myeongdong and Bukchon. Meanwhile, the Seoul museum boom is quietly building a case for cultural itineraries that spread visitors across the country. It echoes the logic behind emerging destinations in our guide to Gangwon Province. A traveler who comes for the NMK may leave planning a trip to Gyeongju. Meanwhile, the programming keeps the pipeline full, too. In 2026, the museum opened "Amazing Thailand: Masterpieces of Thai Art," bringing 239 works of Thai heritage to Korean audiences for the first time. Further collaborations are lined up as well. For example, the Tokyo National Museum, the Kunsthaus Zürich, and the Victoria and Albert Museum are all partners. Each show is another reason to return, and another link in Korea's cultural diplomacy. The Free-Admission Dilemma Here is where the story gets complicated. The very success that free admission helped create is now the reason it may end. The debate has become, in one report's words, a hot-button issue. Whether to introduce admission fees at national museums is now a heated topic in Korea. Many believe the public should start paying for cultural experiences as museums grow crowded. Notably, the pressure comes from the very top. President Lee Jae Myung suggested that state-run museums reintroduce fees, noting that "free admission could diminish their prestige". Still, a real operational problem sits under the rhetoric. Crowds of 6.5 million strain a building not designed for them. In addition, the museum has little hard data on who walks its galleries. So it is laying the groundwork for change. The museum moved its opening hours forward by 30 minutes in March 2026 to disperse traffic. Furthermore, it plans to set up a visitor management system in December as a preliminary step to paid admission. An online reservation and ticketing system will be piloted in the first half of 2027. Yet the economics are stranger than they look. Under Korean law, the museum cannot simply keep what it earns. Under the National Finance Act, the museum is funded by the central government, and any revenue it generates returns to the national treasury. In effect, charging admission would not automatically fund better exhibitions. First, lawmakers would have to rewrite the rules on how museums reinvest earnings. Meanwhile, critics warn about the human cost. For students, older visitors, and low-income families, a free museum is often the only place to encounter history and art without a financial calculation. Charge admission carelessly, and you risk hollowing out the public mission. As one commentary framed it, the real question is not whether culture should have a price. Rather, it is whether the experience is compelling enough that visitors would regret walking away. For foreign visitors, the takeaway is simple. The window of totally free, walk-in access may be closing. Have you been meaning to go? Then 2026 may be the year, before the reservation system and, eventually, the ticket booth arrive. What the National Museum of Korea Signals for Investors Step back from the turnstiles, and a bigger pattern emerges. The NMK's rise is a case study in how cultural assets become economic ones. That translation is exactly what makes Korea interesting to long-term investors right now. First, the museum proves that heritage now drives tourism demand. Indeed, it is no longer a nice-to-have. When millions build a Seoul trip partly around a museum, the spending flows straight into hotels, restaurants, and retail. It is one more pillar under the broader inbound tourism boom drawing hospitality capital back to Korea. Second, the MU:DS story shows that institutions can build commercial engines on top of their collections. A 40-billion-won retail line attached to a public museum is a proof of concept. Accordingly, private operators, from hotels to entertainment firms, are watching closely. Third, the RM appointment shows Korea has learned to fuse its two biggest exports. Pop culture and heritage now feed a single self-reinforcing loop. K-pop drives interest in Korea. That interest fills the museums. In turn, the museums deepen the cultural story that makes the pop culture resonate. In short, it is a flywheel, and it spins faster every year. The through-line connects to a theme we return to often. Korea keeps turning cultural confidence into hard currency. From Netflix originals to museum gift shops, the same instinct appears. Take something authentically Korean, present it with world-class polish, and let global curiosity do the rest. A Museum, Reimagined The people queuing in the Yongsan dawn are not there because someone called a museum important. Rather, they are there because the National Museum of Korea became something a museum rarely is. It became genuinely, urgently desirable. In other words, it became a place worth setting an alarm for. Importantly, that transformation did not happen by accident. It took a once-in-a-generation art donation. It took a retail reinvention, a pop-culture ambassador, and a decade of soft-power groundwork. Now the institution faces its next test. It must stay open, accessible, and beloved while managing crowds that would overwhelm most museums twice its age. For the rest of the world, the lesson is worth absorbing. Korea has shown what a national museum can do with the right mix of ambition and showmanship. As a result, it can compete with the Louvre and the Met on their own terms. The question now is not whether other countries will notice. It is how quickly they will try to copy the formula.
