Ask any printmaker, bookbinder, or paper conservator what paper they reach for when the work really matters, and there is a good chance washi enters the conversation quickly. Japanese washi has been crossing borders for centuries, finding its way into studios in Paris, New York, London, and São Paulo. The reasons artists worldwide have adopted it over Western alternatives are not sentimental. They are practical, aesthetic, and in some cases, deeply personal.
A Paper That Was Built to Last
Western paper, for most of its history, was made from rags and later from wood pulp. Wood pulp introduced something that papermakers came to dread: acidity. Acid breaks down cellulose over time, which is why books and prints from the nineteenth and early twentieth centuries have pages that crumble and yellow. Washi, made from the inner bark of plants like kozo, mitsumata, and gampi, is naturally low in acid and high in long-fiber cellulose. The result is a paper that is genuinely archival in a way that most Western papers are not, at least not without chemical treatment.
Museums and conservators have understood this for a long time. Washi is the standard material used in paper and document conservation worldwide, not because it is trendy, but because it works. A sheet of kozo paper used to repair a fragile watercolor will still be flexible and stable long after synthetic alternatives have begun to fail. At Hiromi Paper, this connection to conservation is central to the mission. The company serves printmakers, artists, bookbinders, and conservators alike, and the papers in the Japanese Papers collection reflect that breadth.
The Fiber Length Difference That Changes Everything
One of the things artists notice almost immediately when they switch from Western to Japanese paper is how the paper responds to tearing. Western paper tears along a fairly clean line but with effort. Washi, particularly kozo-based papers, tears with a soft, feathered edge. That edge is not a flaw. It is a feature. In bookbinding and repair work, a feathered edge creates a seamless overlap that is nearly invisible once dry. In collage and chine-colle printing, it allows layers to meld together naturally.
This behavior comes directly from the long fibers of the source plants. When those fibers interlock during the sheet-forming process, they create a structure that is more like cloth than like conventional paper. The Hosho Professional and Hosho Natural papers at Hiromi Paper are classic examples of this quality. Japanese woodblock printers have relied on Hosho for generations because it can absorb water-based inks without cockling, hold fine detail without bleeding, and survive the pressure of repeated printing passes without tearing.
What Western Printing Papers Cannot Offer
Western papers have their strengths. Watercolor papers from Europe offer thick, heavily textured surfaces that are ideal for certain wet techniques. High-quality etching papers offer controlled ink release. But when a printmaker wants a paper that is simultaneously thin enough to feel the impression of the plate through the sheet, strong enough to survive repeated dampening and drying, and beautiful enough to let the print speak without interference, washi wins the comparison nearly every time.
The variety available through a specialized supplier like Hiromi Paper makes the difference even clearer. The Handmade Papers collection ranges from the gossamer Akaso Kozo at 10 g/m², thin enough to see through, to the substantial Hosho Professional at 85 g/m², with dozens of options in between. Each sheet has a character. The Yukyu-shi series, for example, offers a surface that is simultaneously smooth and softly textured, catching light in a way that enhances rather than competes with the work on it.
Washi and the Global Studio
The story of how washi became a global studio staple is really the story of twentieth-century printmaking. After World War II, American printmakers who had spent time in Japan brought techniques and materials back with them. Artists like Leonard Baskin and Carol Summers began working with Japanese papers and speaking about them publicly. The word spread. By the time Hiromi Paper opened its doors in Culver City, California, there was already a community of artists in the United States who understood washi and were hungry for reliable access to a wide range.
That community has only grown. Today, artists in countries with no direct connection to Japanese papermaking traditions are buying mitsumata and gampi papers because they have tried everything else and found these papers do something uniquely right. The Izumo Mingei Mitsumata Color Series and the ECG Echizen Shikibu Color Gampi Series are examples of papers that have found enthusiastic audiences far outside Japan, used in everything from fine art printing to bookbinding to textile art.
The Tactile Argument
There is also something harder to quantify, which is simply how washi feels. Western paper is often described in terms of weight and tooth, meaning surface texture. Washi adds a third dimension to that vocabulary, which is presence. A sheet of gampi paper from Fukui has a quiet authority to it. A sheet of handmade kozo from Kochi has warmth. These are not accidental qualities. They are the result of specific plants, specific water sources, specific hands, and papermaking traditions that stretch back well over a thousand years.
Artists respond to that quality because they are, at some level, always choosing materials that speak. Paper is not just a surface. It participates in the work. For painters working in egg tempera or gouache, for printmakers pulling editions, for calligraphers working in sumi ink, the paper is never neutral. Washi brings something to the collaboration that most Western papers simply do not, and that is why studios from Berlin to Buenos Aires keep returning to it.
If you are new to washi and want to understand the range before committing to full sheets, the sample books available at Hiromi Paper are the best starting point. Touch is the best teacher here, and once you have felt the difference, the question is no longer why artists prefer washi. The question becomes which washi, and that is a conversation worth having for a long time.
