The Vatican needed to save a prayer handwritten by Saint Francis of Assisi in 1224. Yet the restorers did not reach for the Japanese paper that European conservators had trusted for half a century. Instead, they reached for a sheet made in a small workshop in southern Korea. That sheet was Korean hanji paper. Its quiet arrival inside one of the world’s most demanding conservation labs marks one of the strangest export stories coming out of Korea today.
Yet most outsiders have never heard of it. Korean mulberry paper does not trend on TikTok the way sheet masks or corn dogs do. Yet behind the scenes, this traditional Korean paper has done something remarkable. It has walked into the Louvre, the Vatican Museums, and Italy’s top document-restoration institute. Moreover, it has started pushing aside washi, the Japanese paper that dominated the field for generations. Meanwhile, back home, the same material is being spun into audio speakers, eco-friendly clothing, and building materials.
This is not a nostalgia piece about a fading handicraft. Rather, it is a story about a 1,000-year-old product finding a second life as a modern industry. That shift matters for anyone watching Korea’s export playbook. First, however, you have to understand why the paper lasts so long in the first place.
There is an old Korean saying: paper lasts a thousand years, silk lasts five hundred. For hanji, that is not marketing. The oldest surviving woodblock print in the world is a Buddhist sutra printed on hanji. Remarkably, it has held together for more than 1,200 years. In addition, eight of the thirteen Korean entries on the UNESCO Memory of the World Register are books or documents made on this paper.
Ultimately, the durability comes down to chemistry and craft. Korean hanji paper is made from the inner bark of the paper mulberry tree. Notably, that plant’s fibers are unusually long and tough. During production, artisans boil the bark using natural lye drawn from buckwheat or soybean stalks. As a result, the finished sheet lands at a neutral-to-alkaline pH, typically above 7. Indeed, that single fact explains a lot. Modern factory paper relies on acidic chemicals that trigger a slow chemical burn. This is why old newspapers yellow and crumble within a century. By contrast, hanji does the opposite. It resists the acid hydrolysis that destroys ordinary paper, so it refuses to age the same way.
Similarly, the physical numbers back up the reputation. Traditional Korean paper can reach tensile strength in the thousands of newtons per meter. Meanwhile, some sheets survive being folded well over a thousand times before failing. Furthermore, the bark is harvested only from one-year-old branches in the dead of winter, between November and February. That is when sap flow is minimal and the fibers are at peak strength. In other words, the durability is engineered from the very first cut.
Still, making it is brutal work. The traditional process is sometimes described through the word “baekji.” The term refers to the roughly one hundred touches a sheet passes through before it is considered finished. In practice, bark is boiled, rinsed, strained, pounded, separated fiber by fiber, and dried. Historically, whole villages shared the labor through a cooperative system called pumasi. Under it, neighbors traded work on demanding seasonal tasks. Consequently, hanji was never just a product. It was a community ritual, and that social dimension is now central to Korea’s pitch for global recognition.
For most visitors, the first encounter with Korean mulberry paper happens in a shop in Insadong, Seoul’s cultural district. There, hanji covers every surface in the form of lamps, boxes, fans, and stationery. Certainly, these workshops are lovely. However, they are also a little misleading. They make hanji look like a craft-fair material — pretty, decorative, and firmly stuck in the past.
In reality, the conservation world tells a completely different story. In Europe, Japanese washi had long been the default paper for restoring documents and artworks. That reputation was partly earned and partly the result of aggressive promotion. Japan sent large quantities of washi to Florence after the catastrophic 1966 flood of the Arno River. The disaster had damaged countless books and manuscripts. For decades afterward, washi was simply what serious conservators used.
Then, quietly, hanji started showing up in the labs. Italy’s Central Institute for the Restoration and Conservation of Archive and Book Heritage, known by its Italian acronym ICPAL, began testing Korean hanji paper around 2015. The institute does not restore anything unless it is genuinely valuable, so its standards are unforgiving. After running the paper through physical, chemical, and biological tests, ICPAL certified two types of hanji in 2016. Since then, it has certified five types in total. According to a former director of the institute, hanji satisfied every requirement where earlier papers had fallen short. As a result, it effectively replaced washi as the institute’s paper of choice.
Indeed, the list of things restored with traditional Korean paper now reads like a greatest-hits tour of Western heritage. Consider just a few:
Ultimately, that last case is the tell. The Louvre team switched to Jeonju hanji for one reason: it offered dimensional stability the Japanese paper could not match. For a Korean industry that spent decades in washi’s shadow, being chosen over the incumbent is not a small win. Rather, it is a category shift.
Korea is now trying to convert that momentum into a formal seal of global recognition. In 2024, the government submitted an application to UNESCO. It seeks to inscribe the traditional knowledge and skills behind hanji production on the Representative List of the Intangible Cultural Heritage of Humanity. The final decision is scheduled for the 21st session of the relevant intergovernmental committee. That body meets in December 2026 in Xiamen, China.
Notably, the timing is pointed. Chinese xuan paper was inscribed by UNESCO back in 2009, and Japanese washi followed in 2014. Hanji, despite arguably superior conservation properties, has been the odd one out. For that reason, the application is as much about competitive positioning as preservation. Korea’s pitch leans on the paper’s living, evolving uses, from eco-friendly construction materials to household goods and contemporary art. In short, it is framed as a working material rather than a museum piece.
Still, Korea has reason to be confident. The country has turned 22 nominations into UNESCO inscriptions since 2001. That track record is so strong that UNESCO now reviews Korean submissions only every two years, giving other nations a turn. Meanwhile, hanji-making already carries national intangible-heritage status at home. The government also formally recognizes elite artisans with the title of hanjijang, or hanji master. A handful of these masters, including Hong Chun-su, Kim Sam-sik, and Shin Hyun-se, are named bearers of the tradition. Their workshops, in effect, are the supply chain behind those Vatican restorations.
For readers who want the official file, UNESCO publishes its list of nominations under review for each cycle. Korea’s ambitions here echo a pattern Seoulz has traced across other sectors. Consider the way K-beauty conquered global skincare or how frozen Korean food became a global factory business. In each case, a product refined for a demanding home market gets packaged for the world.
Not all hanji is the same, and the differences start with geography. Three cities anchor the craft, and each has built its reputation on a specific combination of water, climate, and mulberry.
Jeonju is the historic heart of the industry. A 15th-century record noted that the city had the second-highest number of master paper artisans in the country. That prominence was no accident. The region’s water carries very low iron content and sits near neutral acidity, which gives Jeonju hanji its characteristic gloss, absorbency, and archival stability. For that reason, Jeonju is the paper most associated with conservation-grade work, and the city hosts the Hanji Industry Support Center, where a research team develops new techniques and applications. If hanji has a spiritual home, this is it.
Wonju, in the mountainous inland region, took a different path. Its mulberry grows wild across hillsides, embankments, and unused fields, and the area’s clean water produces a notably strong, tough sheet. As a result, Wonju leaned into color. The city became known for vividly dyed hanji and craft applications, and it now runs a hanji theme park and an annual festival built around the material. Where Jeonju sells heritage and archival prestige, Wonju sells creativity and consumer craft.
Andong, meanwhile, operates the largest handmade hanji factory in the country. The operation runs dozens of sheeting stations and produces roughly seventy different types of paper, from window paper to painting paper to backing and flooring grades. In addition, Andong has pursued research into reproducing ancient Buddhist scriptures, including paper suited to copies of the Tripitaka Koreana. The city’s hanji also feeds its famous mask-dance tradition, turning paper into performance objects.
For a foreign buyer or designer, this regional map matters more than it first appears. Hanji made by traditional methods from locally cultivated mulberry has different fiber length, beating, and sheet consistency than industrially produced sheets. In practice, sourcing “hanji” as a generic commodity gets you a very different material than commissioning it from a Jeonju master. Consequently, the most serious contemporary applications, whether in fashion or conservation, tend to involve direct collaboration with named artisans rather than bulk orders.
Of course, heritage prestige alone does not pay the bills for a whole industry. The more interesting question is commercial. What happens when engineers, rather than conservators, get their hands on Korean mulberry paper? The answer, increasingly, is that hanji is being reborn as a high-performance material.
First, take audio. Hanji has an irregular fiber density, so speaker cones made from it scatter internal resonance instead of amplifying it. Consequently, some audiophile makers argue that hanji cones deliver cleaner, more natural sound than synthetic equivalents. It is a niche, but a telling one. The same fiber structure that makes the paper durable also makes it acoustically useful.
Meanwhile, fashion has run in a parallel direction. Designers have spun hanji fiber into yarn to create “hanji-wear,” clothing marketed as breathable, durable, and eco-friendly. One Korean knitwear label built an entire product line around it. Meanwhile, another designer produced a collection organized around the ideas of ephemerality, disposability, and sustainability. The fashion industry is drowning in synthetic waste. For that reason, a compostable fiber with a thousand-year pedigree is an appealing story.
The sustainability angle is where the industrial and cultural cases converge. Traditional Korean paper is biodegradable, made from a fast-renewing plant, and produced without the acidic chemistry of modern mills. In addition, its breathability and humidity-regulating properties suit eco-conscious interior and building applications. That is precisely the modern use-case Korea highlighted in its UNESCO application. The broader arts-and-crafts materials market is growing steadily worldwide, and premium sustainable materials sit in the fast lane. You can see the same appetite for heritage-meets-innovation in Korea’s silver economy startups, where old sectors are being retooled for new demand.
Here the honest caveat arrives. Hanji is not, and will never be, a billion-dollar consumer category on the scale of K-beauty or webtoons. The numbers are far smaller and far quieter. Still, that is precisely what makes it interesting to a certain kind of investor.
The broader South Korean art-and-craft market, which includes paper crafts as a core segment, is projected to add more than 450 million US dollars over the 2024–2029 window, according to industry research. Hanji sits inside that flow as a premium, heritage-branded material rather than a mass commodity. Meanwhile, the global arts-and-crafts market overall is growing at roughly 7 percent a year, driven by demand for sustainable, handmade, and personalized goods. In other words, the tailwinds behind hanji are structural, not faddish.
The more compelling opportunity, however, is not selling sheets of paper. Instead, it is licensing what hanji represents. Korea has repeatedly shown that its cultural exports compound when a traditional asset gets attached to a modern platform. Consider the trajectory of the Korean webtoon industry, which crossed 2 trillion won and now feeds Netflix adaptations worldwide. Hanji is nowhere near that scale, yet the mechanism is identical: take something distinctly Korean, wrap it in a globally legible story, and let the validation travel.
For entrepreneurs, three entry points stand out. First, conservation supply, where certified hanji commands premium pricing from museums and archives that have few alternatives. Second, sustainable materials, where the paper’s compostability and alkaline chemistry fit the green-premium segment in fashion, packaging, and interiors. Third, experience tourism, where hanji workshops convert cultural curiosity into repeatable revenue. Notably, each of these plays sidesteps the brutal economics of competing on raw paper volume against industrial mills.
For all the good news, the hanji industry faces a problem no Vatican endorsement can fix: people. Making hanji by hand is punishing, seasonal, low-margin work. Meanwhile, Korea’s demographic squeeze is hitting traditional crafts hard. The number of working hanji masters is small and aging. Understandably, younger Koreans are reluctant to sign up for a life of boiling bark in freezing water.
Importantly, this is not a hanji-specific problem. Instead, it is the same generational reluctance reshaping everything from family restaurants to manufacturing. Seoulz has covered that dynamic in its look at Korea’s shrinking workforce and startup economy. When the current masters retire, the knowledge does not automatically transfer. That is exactly the risk UNESCO status is meant to slow. Recognition raises the tradition’s prestige and, ideally, its economic viability.
Fortunately, there are hopeful signs. Cities like Jeonju, Wonju, and Andong have built hanji museums, festivals, and theme parks. These pull in tourists and, crucially, expose the craft to younger visitors. The Jeonju Hanji Museum offers free hands-on papermaking, and Wonju hosts an annual hanji festival. For travelers, these rank among the more meaningful cultural experiences on offer. In particular, they fit the slow, hands-on tourism that has grown popular in recent years. Insadong studios, for their part, keep the material visible in daily commercial life.
Strip away the romance, and the hanji story rhymes with almost every successful Korean export of the past two decades. First, a product gets refined to an extreme standard inside a demanding domestic market. Next, it earns a credibility stamp from a respected foreign gatekeeper — a European museum, a global streaming platform, a viral American grocery aisle. Finally, it scales outward on the back of that validation.
For a foreign investor or entrepreneur, the practical lesson is simple. Watch the materials layer, not just the consumer layer. Everyone sees K-beauty serums and K-pop albums. Fewer people notice the industrial substrate underneath. Consider the cold-chain logistics behind frozen food, the retail infrastructure behind cosmetics, and now the thousand-year fiber behind Korea’s sustainable-materials ambitions. In particular, hanji sits at the intersection of three trends investors already track: heritage branding, sustainability, and high-performance materials.
Looking ahead, the December 2026 UNESCO decision will be the next big marker. If hanji is inscribed, expect a surge of government support, export promotion, and startup activity around the material. Other Korean sectors accelerated after their own moments of global validation. If it is not inscribed, the commercial case will keep advancing anyway. After all, the Vatican and the Louvre have already voted with their restoration budgets.
In any case, the humble sheet of Korean hanji paper has already done the hard part. It walked into the most demanding rooms in the Western art world and earned its place. For a material once written off as a dying craft, that is a rewrite worth watching. The paper, fittingly, will outlast the debate by about a thousand years.
