Kajiya – the Life and Work of Rural Blacksmiths in Medieval Japan

What was life like in a Japanese village when the rhythm of the day was set by the strikes of a hammer? A story of craftsmanship, fire, and responsibility that shaped the medieval countryside.

Tezukuri no michi

In a medieval Japanese village, the forge was the first place to awaken. Above its entrance hung a bundle of dried yomogi or a modest shimenawa rope, just like at small rural shrines. Not for decoration: it marked a boundary of realms. Inside burned a fire that no longer belonged solely to humans—a fire both dangerous and necessary, ordinary and ritual, within which tools were born that determined whether the community would survive another year. For the villagers, this place had its own scent, its own sound, its own gravity. When the kajiya—the village blacksmith—immersed a rod of iron in the glowing ro (炉), and the air was enlivened by the strokes of the tenbin-fuki bellows, everyone knew that one must respect the solemnity of work and experience.

Although he did not carry a sword and was not a hero of chronicles, he held in his hands a power more tangible than that of many samurai. It was his work that shaped the tools with which fields were plowed, houses built, meals prepared, and the village protected from the anger of others. In Muromachi-period Japan, the hand was the measure of a person’s reliability and dignity, and the blacksmith embodied this truth more fully than anyone else. He was not a philosopher—but he had his own philosophy: simple, austere, born of repetition and focus. In a world where tools served a single family for decades, and a poorly forged plowshare could ruin an entire harvest, patience and humility before matter were not beautiful slogans but conditions for survival. The Japanese spoke of tezukuri no michi—“the way of handmade work”—which bound technique to ethics, and craft to character.

This is why the forge was not an ordinary workshop. It was a shrine, and within it prevailed a kind of silent discipline—unforced, yet natural, the kind that arises from responsibility for others. Every tool that left the blacksmith’s hand was part of a wider order: buildings, boats, kitchens, rice fields, and the forests around the village depended on the quality of his work. And he himself lived in the rhythm of the fire, which shaped and tempered—both metal and spirit. This world—a world of austere beauty, where matter resisted and a person learned to listen to it—is worth returning to, because in the sound of the hammer striking iron we hear more than the history of craftsmanship. We hear a tale from old Japan about the pride and humility of labor, the experience and responsibility inherent in creation.

Let us now look more closely at the life and work of the kajiya—the rural blacksmiths of medieval Japan.

SCENE

In the Forge

At dawn, the mist still drifted between the thatched roofs, heavy as the moisture that had descended overnight from the forested slopes of the hills. The birds were only beginning their chaotic calls when the first sound of the day—not the rooster, not the creak of doors, but the dull thud of a hammer striking an anvil—echoed through the village. Everyone knew that the kajiya was already at work. He always awoke before the others, as if the fire of the hearth began in his chest and would not let him sleep. In the dark interior of the forge, where the beams were coated with soot and the smell of heated iron mingled with the dampness of morning, the first orange glimmers of the brazier appeared.

Rural forges of the Muromachi period looked different from the later workshops of castle towns—they were simple, austere, often built at the edge of the village, by a stream from which water was drawn to quench the steel. The floor was beaten clay, and by the wall lay a pile of charcoal prepared by foresters from a neighboring settlement. In the forge creaked the long wooden fuigo bellows—a heavy rectangular box that a boy, the blacksmith’s apprentice, pushed back and forth, forcing air into the clay nozzle of the hearth. Every movement had to be performed with an even rhythm, like in the court music of gagaku, which the boy would likely never hear in his life. His task was called tenbin-fuki (天秤吹き)—weighing the air—because he had to sense when the fire needed to be fed and when it should be allowed to settle.

The blacksmith—the kajiya (鍛冶屋)—had a face furrowed with wrinkles, though he was not yet old. Life in a forge is measured not in years, but in thousands of hammer blows, by the rhythm of a day that never changes. His hands were broad, cracked, marked with old scars from sparks. In Japan it was said that an artisan “thinks with his hands”—te de kangaeru—and the blacksmith was a master of this. Every gesture, every immersion of the glowing blade into the water vat, every turn of the metal in the tongs was part of the body’s memory, trained through tens of thousands of repetitions.

That morning he was working on a hoe. The harvest was due in a few weeks, and the farmers from nearby fields had asked him to prepare their tools. Metal was not as accessible then as in later centuries—it came from local bog iron pits or from itinerant merchants who brought steel in ingots. Therefore nothing was wasted: old tools were reforged, cleaned, given new edges. The kajiya could make a dull, worn piece of iron recover its sharpness, strength, and life. Craftsmen called this naoshi (直し)—a repair that was at the same time a rebirth.

When the metal began to glow with incandescent white, the blacksmith drew it from the fire and struck it swiftly with the hammer. The sounds spread through the village like signals: three short beats—the beginning of shaping; long and slow ones—the edge is near; quick, strong strokes—time for quenching. The boys who were on their way to the irrigation channels to divert water stopped for a moment, for from the very tone of the blows one could tell what the master was working on. To them, the kajiya was a kind of diviner—the one who knew first what the coming season foretold, by the tools he was making.

Above the forge entrance hung an old bundle of dried yomogi (蓬), a plant considered in rural Japan a natural amulet protecting against evil spirits and the “unclean” energy carried by fire and metal. Custom dictated hanging such a bundle at places where the elements might slip out of control—in forges, hearths, and even pottery kilns—to symbolically separate the space of humans from the space of spirits. For the villagers it was also a visible sign that inside burned a living, dangerous, yet sacred fire whose gravity had to be respected, for through it were made the tools essential for the survival of the entire community.

For centuries, Japanese forges were places of almost ritual character. Lighting the hearth followed certain rules, quenching was always done in silence, and the water in the vat was changed according to specific lunar phases, for it was believed to influence the properties of the metal. This syncretic way of thinking—part practical, part superstitious—was the everyday reality of Muromachi blacksmiths.

At one point the blacksmith paused and lifted the hoe’s edge to the light. His eyes travelled across its surface as if he were examining a human face. In his philosophy, a tool that daily bears the weight of life—the weight of harvest, the weight of labor—deserves respect.

The chain of dependence was simple: without a good sickle there is no rice, and without rice there is no life.

A moment later the first customer peeked into the forge—a villager in a faded hemp kosode (小袖), carrying an old axe with a cracked blade. He bowed deeply, as if standing before someone of far higher rank.

“Kajiya no Ojisan, can this be repaired?” he asked a little shyly, showing the cracked plowshare.

The blacksmith merely nodded. In his world there was no need for many words. The metal spoke more loudly.

Soon the entire village was fully awake: women carried water, children chased each other between the houses, and from the fields came the first rustle of reeds. But above all rose the rhythm of the forge: hammer, fire, the hiss of quenching. In the Muromachi period, as in the centuries before and after, the life of the village depended on its forge. And the blacksmith—quiet, focused, almost meditative in his everyday routine—was the guardian not only of tools, but of the community’s very ability to survive.

It was thanks to his work that the earth bore crops, houses rose, boats moved, and each day could begin anew.

Who was the rural blacksmith of medieval Japan?

The rural blacksmith of old Japan rarely found his way into chronicles, rarely became the hero of stories, and never achieved the glory of swordsmiths who worked in an atmosphere of religious concentration, surrounded by legends of divine blades. And yet it was he, the humble kajiya (鍛冶屋), who held in his hands the pulse of the village—its safety, its harvest, its rhythm of life. Without his hammer, the fields would stand still, the plow would cease to function, and the life of the entire community would quite literally “rust away.” Travelers could live without silk fabric, a samurai without an elegant daishō of katana and wakizashi would not starve, but a peasant without a sharp hoe, axe, or plowshare simply would not survive the year. In this sense the anonymous blacksmith was the foundation upon which the Japanese village stood. And not only the Japanese one.

The very name kajiya (鍛冶屋) is remarkably vivid. The first kanji, 鍛, means forging, tempering, and training one’s character; it is the same character found in the word tanteru (鍛える)—to refine oneself, to polish one’s skills. The second, 冶, refers to smelting metal and guiding heat through the skilled hands of the craftsman. The third (屋), “ya,” means house. Together they form a concept of striking power: “a house where metal is forged and perfected by heat and by hand.” In Japanese, it was one of those names that resembled a title more than a profession—akin to tōshi (刀師, master swordsmith) or gusoku-shi (具足師, armorer). The rural blacksmith, however, had no privilege of high rank; he was a master of the everyday, but without ceremony, without the aura of Shintō and Buddhist rituals that surrounded swordmaking.

In Muromachi and early Edo Japan, the blacksmith occupied a somewhat unusual position in society. Formally he belonged to the artisan class—shokunin (職人)—but in practice he lived closer to the peasants (hyakushō 百姓). Many of them owned small fields with which they supported their families, for the forge alone did not always provide sufficient income. The spring season of tool repair was intense, but summer could be quiet. For this reason, their life rhythm often resembled that of a farmer: work at the fire alternating with work in the soil. This hybrid position granted blacksmiths considerable independence, especially since metalwork was a rare and difficult skill. Though they did not belong to the elite, they were respected—at least to the degree a village could offer someone who had neither abundant land nor a name known at the castle.

Their social standing was also shaped by the economic policies of the late medieval era. The system of rakuichi rakuza (楽市楽座—literally “free markets, free guilds”) introduced by many daimyō during the Sengoku period abolished local monopolies and marketplace taxes, promoting free trade. Thanks to this, blacksmiths could sell their products and services not only to farmers of the nearest village, but also to merchants who traveled from town to town. Even so, in the Edo period, when castle towns began organizing professional life by trade and district, the rural blacksmith remained somewhat outside these structures. Unlike urban blacksmiths, he was not registered in strictly controlled guilds and did not fall under such strong regulation. His workshop lived according to its own rhythm, in harmony with the seasons, the needs of the village, and local tradition.

Most passed their craft from father to son—tools, anvils, casting molds, and even the rhythm of hammer strokes formed a kind of family heritage. Old economic records mention how agricultural tools were handed down through generations, and their repair was treated almost like the care of an object of ancestral importance. A blacksmith who knew a man’s father’s tools understood how to fit a new blade, how to “feel” the metal so as not to alter the balance and workings of the implement. For this reason he was given enormous trust—because the quality of his forging determined the harvest, safety, and sometimes even life itself.

This social respect also arose from a work ethos that—though never written down—grew naturally from the character of the blacksmith’s daily life. Unlike the tōshi associated with Shintō rituals, rural blacksmiths followed a more pragmatic philosophy: metal must be “felt,” fire must be “understood,” and hard work is the only path to mastery. It was said of them that they worked according to the principle of te de kangaeru—“to think with the hands” (手で考える). Knowledge of metal was intuitive, nonverbal, passed on through observation and repetition until the hand itself understood when the iron “sings,” when it is soft like mochi rice cake, and when it is hard and springy like winter bamboo.

It is also worth remembering that a rural forge produced not only tools. The blacksmith often repaired door locks kugikakushi, fittings for nagamochi chests, small elements of harnesses, and sometimes even chains, well hooks, or parts of hearths. In this way he became the guardian of the security of homes and farms. When a young farmer brought a cracked plowshare to the forge and asked, “Kajiya no Ojisan, can this be repaired?”, he was not asking merely about a tool. In reality, he was asking about the fate of the entire season’s labor.

The rural blacksmith, humble and anonymous as he was, thus became one of the unofficial pillars of old Japan. It was he—not the sword, not the armor, not the palace—who formed the link between a family’s past and its future. His hammer did not engrave clan names into history, but it struck the rhythm of everyday life. And though his forge was small, low, and dark, in a sense it was there that the fire burned which kept the village alive.

A Day in the Life of the Kajiya

The everyday life of a rural blacksmith in medieval Japan began before dawn, when mist filled the low thatched roofs of the village and the cold, damp breath from the nearby rice paddies pressed through the gaps in the wooden walls. The first to awaken was the fire—for although it went out during the night, there was always a bit of embers left in the clay hearth 炉 (ro), covered with a thick layer of ash.

The blacksmith would rake it aside with a short bamboo poker and add a few pieces of carefully selected sumibi charcoal, burned from hard ubamegashi oak or from red pine akamatsu, whose resin gave the embers high temperature and stability. As the fire gathered strength, the blacksmith adjusted the fuki, a simple hand-operated blower, or a more advanced tenbin-fuki (天秤吹き) system, where a weight raised and lowered an air piston, gradually heating the iron until it reached a more flexible state.

The first customers were farmers, appearing at an early hour with hoes kuwa, sickles kama, and plowshares suki wrapped in straw. Morning was the time for immediate repairs, those that could not be put off: dulled edges, cracked fittings, chipped blades. By feeling the metal, the blacksmith could in an instant sense whether a tool required only naoshi (直し)—a quick repair and rehardening—or a complete replacement of parts.

Quenching looked simple, but demanded vigilance: the heated metal was cooled not in water, but in a mixture of ash and sand, which produced a milder effect and less brittleness—unlike the process associated with sword-making. Peasants most often paid in rice, soybeans, or firewood, though sometimes there was also an exchange of services—an everyday reality in closed communities operating alongside the great markets of the cities.

The rhythm of the year was set by the growing seasons. During harvest time, the pounding in the forge rang out almost without pause, and the blacksmith sometimes slept only a few hours on a hard mat of rice straw, because each day of delay meant losses for the farmers. At such times the workshop changed its character: from a place of solitary work it became a kind of social center, where some waited for their tools, others carried water, and still others came just to watch molten metal take shape. In the busiest periods, during long repair sessions, the blacksmith moved from one task to another without a break: forging a plowshare, hardening an axe, fitting the metal fittings of an ox yoke, and even repairing iron hardware used for building boats on a nearby river, if the village lay close to the coast.

The blacksmith’s wife, usually equally skilled in the craft, played a key role in the workshop’s daily life. Women were responsible for forging small elements such as nails kugi, small clasps kanamochi, hooks kagi, or blades for kitchen knives, because this required precision rather than strength. They operated the small stone whetstone toishi on which they finished the surfaces of tools, and also handled sales, talking with villagers, arranging pickup times for tools or negotiating barter exchanges. Their work was less visible, but without it most forges would not have functioned smoothly.

Children appeared in the workshop naturally and gradually. At first they sat in a corner and watched the rhythm of their father’s movements, the sound of the hammer, and the changing colors of the heated iron; later they passed tools, sorted pieces of charcoal by size, and learned to recognize which hammer blow created a flat surface and which stretched the metal into a long strip. The first lessons were not formal—they were simply participation in the life of the forge, as had been the case for generations. Boys—and more rarely girls—learned through direct observation, and the ability to “read metal” was transmitted not in words, but in actions repeated hundreds of times, in accordance with the Japanese concept of minarai—learning through watching and imitation.

The forge was not only a place where metal was smelted, but the center of village life—a point where people’s needs, the cycle of nature, and the skill of the craftsman converged, his work—anonymous as it was—sustaining the entire local world.

Workshop or Temple?

The blacksmith’s workshop in a medieval Japanese village was not a place where the philosophy of work was practiced in words, but where it was forged by the hand. A simple craftsman who knew no sutras and did not quote the classics nevertheless had his own, deeply embodied understanding of the world—rooted in the earth, in the rhythm of the seasons, and in the heat of the hearth. The Japanese spoke of tezukuri—literally “made by hand”—but behind this word lay an entire vision of the human being. In that vision, the hand was not just a tool but an extension of the mind, a way of taming the chaos of nature and giving it a form that served life.

The blacksmith knew that it depended on his hands whether spring would begin smoothly, whether the harvest would go well, whether the neighbor’s family would have something to cut grass with, and whether the fisherman’s boat would not sink. Every tool that left his forge was at once practical and—in a completely unconscious way—metaphysical: it represented the transformation of the raw world into an ordered one. Hence the particular respect for his own work. The rural blacksmith did not speak about this aloud; he simply knew that if the hand worked carelessly, the whole village would fall ill.

A simple set of tools stood in the forge, but each had its weight and its history. By the hearth 炉 (ro) lay the hammers—from the heavy Ō-zuchi to the light kozuchi used for precise blows. The anvil, usually set into a wooden block, had been worn down by decades of work. The bellows—most often a double tenbin-fuki, operated by foot or hand—pushed air in a rhythm that became part of the blacksmith’s life, almost like breathing. Nearby lay chisels, tongs, iron casting molds, and dull stones for preliminary sharpening. Each tool was an extension of a different sense: the hammer was strength, the chisel—precision, the bellows—heat, the anvil—foundation.

At the center of everything, however, was the fire. Pure, forge-fire, treated with a mixture of fear and reverence. Fire purified the metal, burned out its weaknesses, and allowed a new form to be born. For centuries, blacksmiths and farmers believed that the forge flame also had a symbolic, ritual dimension—that is why above the entrance to the workshop there often hung a bundle of dried plants or a piece of straw shimenawa rope. It indicated that the threshold of the forge was the boundary of something special: a place where a person touches forces greater than himself.

This work, though loud, was also a path toward inner concentration. The Japanese concept of shokunin kishitsu—the “spirit of the craftsman”—did not mean simply “striving for perfection,” but rather the union of pride and humility. The blacksmith knew he could make mistakes, that every blow had consequences. That is why his movements were repetitive, but never mindless. In those repetitions lay the maturation of the mind—not reflective, but bodily, developed through the tension of muscles, through the heat of the fire, through the resonance of metal.

And between each stroke of the hammer there was silence. This silence did not arise from contemplation, but from necessity. The blacksmith had to listen: to how the heated iron rod sounded, how its color changed, how it behaved on the anvil. It was there that the most important part of his philosophy took on substance—the part he could not have expressed in words, but which he conveyed in every tool that left his workshop. A deep concentration, experience, and self-assurance mixed with reverent awe and humility. That peculiar blend of pride and modesty that only experts, true masters, possess.

That is precisely why the forge was a temple.

The Range of Work of Rural Blacksmiths in Medieval Japan

The village kajiya was a craftsman whose work touched nearly every aspect of daily rural life—from the rice fields to the kitchens and the carpenters’ workshops. He primarily produced agricultural tools that had to be adapted to local soil conditions and cultivation methods. Sickles (kama), hoes (kuwa), plowshares (suki-no saki), axes (ono), as well as special rice hooks and mallets for driving posts formed the foundation of village functioning. Each of these tools had regional variations—on steep terraced fields lighter hoes were used, while in the heavy soils of Kantō, thicker iron cores were preferred for plowshares.

A second, equally important field involved tools for woodcutters and carpenters. Japanese architecture relied on wood—from bridges and granaries to minka-style houses. The kajiya therefore prepared axes with different profiles, chisels (nomi), wedges, double-edged saws (nokogiri, though often sharpened by the carpenters themselves), and heavy hammers used in carpentry. Thanks to such tools it was possible to create intricate joinery like kigoroshi and hozo-shikuchi, all without nails—something in which the rural blacksmith participated indirectly by ensuring the proper shape and sharpness of the implements.

An important element of his work also included kitchen knives, although rural knives differed greatly from the later masterful blades of Sakai or Echizen. These were simple, often single-piece hocho, used for vegetables, freshwater fish, and the meat of wild animals. Despite their simplicity, their production required precision, for the knife had to be easy to sharpen and not break when cutting harder foods. It was from such rustic blades that the later, more refined carving tools of Edo-period craftsmen eventually developed.

Though modest in appearance today, nails (kugi), metal fittings, clasps, and hinges were of immense importance. Japanese construction rarely relied on nails in major structures, but they were essential for smaller elements—doors, chests, lids, carts, and agricultural tools. The village forge was thus a place where an entire range of small metal components was produced, without which the village could not function.

In coastal regions, near lakes or along rivers with a developed fishing culture, the blacksmith also played a vital role in boatbuilding. He produced iron fittings, spikes for joining planks, hooks, chisels for shaping sugi or fir wood, as well as metal parts for nets and fishing rods. The greater the village’s dependence on the sea, the more crucial the blacksmith’s role became in maintaining its fleet of wasen.

All this activity was intertwined with technological changes that, beginning in the Muromachi period, reached even the most remote villages. The development of Japanese tamahagane steel and the refinement of tatara-yaki furnaces had a major impact on the quality of metal available to rural craftsmen. Cheaper, lower-quality iron from larger centers such as Bizen or Izumo also appeared, and village blacksmiths reworked and strengthened it for their own needs. Thanks to this, they could create tools more durable than those of earlier centuries, while still perfectly suited to local life.

The Way of Handmade Work

The work of the rural kajiya was deeply rooted in Japan’s philosophy of everyday life, in which the hand became the center of the entire human experience. It was thanks to the hand that fields were plowed, houses built, meals prepared, and the village defended against danger. The hand was a tool, but also a measure of a person’s reliability and integrity. In such a world, craftsmanship was not an addition to life—it was its fullest expression. When the blacksmith took the hammer into his hand, he was not merely performing an occupational function; he was participating in something deeper, something the Japanese would call tezukuri no michi—“the way of handmade work.”

Within this path, the ethics of craftsmanship held a special place, shaped not by books but by practice. Patience, repetition, and attentiveness were moral virtues, but also conditions for the village’s survival. The blacksmith knew that one careless movement could break the blade that was the family’s only tool during harvest. He therefore learned humility before the materials—iron, fire, but also time, which dictated the pace of his work. This humility was not resignation, but an element of Japanese craft consciousness: the creation of something durable in a world that is inherently impermanent.

This is why the forge was not a place of loud pride or ostentatious virtuosity. It was a space of quiet responsibility, where the work spoke for the person. No monuments were erected for the kajiya, but he was remembered in the rhythm of the day—in the way a tool fit the hand, in the smoothness of a knife’s edge, in the certainty of a sickle’s cut through the morning dew. This memory was natural, unobtrusive; part of local life, which treated the craftsman as the discreet backbone of the community.

At the same time, the blacksmith viewed the world through the prism of his work. Change was natural to him—metal softened, hardened, cracked, and returned to its form. Permanence and transience were not opposites; they were two states of the same matter. The dulled surface of the anvil, the scorched board beneath the hearth, the hammer with a handle polished smooth. Nothing in the forge was perfect, yet everything was real, shaped by time. It was precisely in this imperfection that value lay—in the awareness that a tool aged together with the hand that created it.

The heritage of Japan’s kajiya did not vanish with the fall of feudal villages. It survived in small workshops, especially in the prefectures of Shimane, Niigata, and Iwate, where forges continue to use local iron, traditional tatara furnaces, and old tempering techniques. Contemporary Japanese kitchen knives, highly valued worldwide, are direct heirs to this tradition—just as the artisan tools of Echigo or decorative metal elements in folk architecture are.

The forge also became a symbol of old Japanese life: a rhythm of work in which people adapted themselves to the seasons rather than the other way around; a community living in a cycle of mutual dependencies; a relationship between humans and nature in which technique was not a tool of domination but a form of coexistence. When we look at the rural blacksmith from the perspective of the present, we see not simply a craftsman, but a guardian of a certain way of life—slow, attentive, grounded in respect for matter and for people.
