Etchu Washi Paper

What Does a Piece of Paper Have to Do with a Travelling Medicine Kit?

Toyama's papermakers built part of their trade around a customer nobody visiting a paper mill would expect: the travelling pharmacist. Salesmen from Toyama carried medicine chests door to door across Japan under a system known as okigusuri, sometimes translated as "use now, pay later." They left a chest of packeted pills and powders in a rural household on one visit, and on the next they opened the chest, counted what was gone, and charged only for that. Nothing was billed for what sat untouched. Every packet needed wrapping, and the wrapping needed to survive months in a peddler's pack without splitting, tearing, or letting damp air in. That demand shaped paper made around Yao, a district of Toyama City, where sheets developed into what is remembered as yakuhoshi, medicine-wrapping paper. The valleys behind it supplied kozo, the mulberry-family bark that gives Japanese paper its long, tangled fibers. Workers steamed the bark, beat the fibers loose, floated them in water thickened with mucilage drawn from tororo-aoi root, and lifted the mixture onto a bamboo screen called a sukibune, one sheet at a time, before pressing and drying the paper in the open air. Etchu washi is not a single product but a shared name for three valleys that each solved this problem their own way: Yao washi in Toyama City, Gokayama washi in Nanto City, and Hiruya washi in the mountains of Asahi Town. Beyond medicine wrapping, the same hand-beaten sheets found their way into dyed paper and paper made for calligraphy and printmaking, uses that still carry the craft today.

Same Bark, Two Prescriptions

Travel two countries west and a similar bark meets a similar need. Korean papermakers have long produced hanji from mulberry fiber, and one of its steady markets has been hanbang, traditional Korean medicine: hanji has wrapped herbal remedies and carried official documents, and it holds up well enough that conservators reach for it when repairing the country's own cultural properties. Set a sheet of yakuhoshi beside a sheet of hanji and the kinship is immediate — the same bark, beaten by hand into a long-fibered, breathable sheet, pressed into service by a similar kind of customer. Conservators reaching for hanji when a centuries-old document or artifact needs repair are, in effect, asking mulberry-bark paper to do the same job it was originally made for: hold together under stress longer than most materials placed near it. In both places the paper also drifted toward other practical goods built to be handled roughly: umbrella paper as much as medicine paper, a covering meant to be folded, rained on, and carried, not admired under glass. Further south, in Chiang Mai, papermakers work a related lineage of mulberry-bark paper called saa, folded into umbrellas and fans rather than medicine packets. None of these traditions borrowed directly from the others. What they share is a plant and a purpose: durable, hand-lifted paper asked to do practical work across a wide stretch of Asia, not only in Japan and Korea.

So Why Did Two Countries Reach for the Same Fix?

The paper in Toyama and the paper in Korea did not converge because papermakers copied each other across the sea. They converged because both regions built a medicine trade that needed paper sturdy enough to trust. In Toyama, the answer was a peddling network well known enough to carry the region's name into common speech — Etchu Toyama no okigusuri, the medicine chests of Toyama, carried nationwide by travelling salesmen who restocked what a household had used and left the rest. In Korea, the answer was a home-grown medical tradition, hanbang, that needed packaging durable enough for both the remedy inside and the record of its prescription written on the wrapper — a wrapper that was also, in effect, a label the patient had to be able to read after weeks of handling. Different economies, different institutions, the same underlying pressure: a medicine trade only trusts a wrapper that survives handling, and hand-beaten mulberry paper met that bar in both places. The split had little to do with the bark itself. It came down to which country's medicine trade needed the paper first, how large that trade grew, and how far it carried the paper once it existed.

Three Valleys, One Designation

Papermaking in this part of Toyama is old enough to appear in Nara-period records connected to the Shosoin, and Hiruya washi in particular is said to trace back to around the year 770, brought in from what was then Omi Province. What is now recognized under the single name Etchu washi covers production across Toyama City, Nanto City, and Shimoniikawa District's Asahi Town, and the craft's designation record lists June 9, 1988 — the sixty-third year of the Showa era — as the date it received formal recognition. Under that one designation sit three distinct working traditions rather than one workshop tradition repeated three times: Yao washi, built around medicine wrapping for the okigusuri trade; Gokayama washi, worked in the mountain hamlets of Nanto; and Hiruya washi, made in the valley around Asahi. Each was shaped as much by its own geography and its own customers as by the shared name that now covers all three on paper. A visitor moving between the three would find a family resemblance in the bark and the technique, but not one workshop repeated three times over — closer to three cousins who grew up in the same mountains and ended up in different trades.

What Happens When the Medicine Trade Shrinks?

Okigusuri itself is a shrinking business. Fewer households keep a travelling pharmacist's medicine chest in the cupboard than once did, and fewer restocked packets means less call for a paper built specifically to wrap them. Yao washi's original customer is thinning out even as the craft continues through dyed paper and through calligraphy and printmaking sheets bought by artists rather than pharmacists — a shift in customer that keeps the hands moving but changes what the paper is asked to be. Hiruya washi carries a sharper version of the same risk. At one point the hamlet's papermaking tradition rested on a single remaining maker, the kind of situation where a craft's survival depends on one person's health and one person's willingness to keep teaching a process that took a lifetime to learn properly. There was no workshop to fall back on if that one maker stopped, and no second household in the hamlet still beating kozo bark to carry the process forward.

The Apprentice Who Kept Hiruya Washi from Going Silent

What very nearly went quiet in Hiruya did not, because in 2003 an outside papermaker took up the craft directly from that last remaining maker, learning the process by watching and listening rather than from a written manual. That is the version of the story that survives here: not an unbroken line running back through the centuries untouched, but a craft caught at the edge and handed forward because one person chose to learn it by hand, gesture by gesture, from the one person left who still knew it. If the valleys behind Etchu washi stopped, what would disappear is not only a papermaking technique but the commercial history folded into every sheet — paper made to travel in a peddler's medicine chest across the country, and a Nanto and Asahi tradition that came within one retirement of ending before someone decided, in person, to keep it going. The technique itself would survive somewhere, written down or filmed. What would not survive is the direct line from one pair of hands to the next, the part of the craft that only passes when someone stands in the same room and does the work alongside the person who already knows it.
