In a medieval Japanese story, household objects cast into the street for New Year cleaning gather to complain about being discarded. A rosary, a club, writing materials and assorted vessels have spent years serving human owners, only to be thrown out. Some want to punish the people who discarded them; others plead for restraint. The quarrel eventually leads to a monstrous transformation, and the former tools turn against the inhabitants of Japan’s imperial capital.
The creatures are known as tsukumogami. Later accounts often describe them as objects that acquire spirits after a century of use. The medieval texts tell a more involved story. The Tsukumogami ki, or Record of Tool Specters, is an illustrated tale written during Japan’s Muromachi period, between the fourteenth and sixteenth centuries. Its action takes place centuries earlier in Heian-kyō, the imperial city now called Kyoto.
Their attacks eventually end in repentance. These discarded possessions become Buddhist practitioners and finally attain enlightenment. The story begins with the familiar task of clearing out a house, then uses the tools’ rebellion to consider whether things regarded as lacking consciousness can attain Buddhahood. Its illustrations give faces and limbs to objects whose work once depended entirely on human hands.
What Were Tsukumogami?
In Japanese literature and painting, tsukumogami are manufactured things that come alive: tools, vessels and other objects ordinarily handled by people. Their age is often part of the explanation, though no single rule governs every surviving depiction. A sandal, pot or instrument might acquire arms and a human face while remaining recognizable. The characters in the medieval narrative can undergo more radical changes, taking the shapes of animals, people or demons.
The Tsukumogami ki is part of the otogizōshi tradition, a body of short illustrated stories popular in medieval Japan. A single work might mix comedy with frightening episodes, romance or religious instruction. Readers followed the pictures and writing along a scroll as it was gradually unrolled. The illustrations could make an animated implement funny or frightening, while its conduct carried a Buddhist teaching.
Scholar Noriko T. Reider has translated the best-preserved account into English. Its opening invokes a supposed earlier source, the Miscellaneous Records of Yin and Yang, which claims that tools and vessels acquire spirits after a hundred years and can deceive human beings. Researchers have not securely identified that cited work. That quotation alone cannot establish whether a fixed hundred-year rule existed outside the story or how widely people accepted it.
The tale records how medieval writers imagined objects acquiring uncanny lives. Its writer adapted older ideas about unsettling objects into a plot driven by disagreement, violence and Buddhist conversion. Modern readers often call such supernatural beings yōkai. That label is helpful, provided we remember that Japanese writers and artists did not always classify or name uncanny creatures in the same way.
Why Did Old Tools Become Dangerous After Ninety-Nine Years?
A pun helped connect these creatures with the age of ninety-nine. In episode sixty-three of the Ise monogatari, or Tales of Ise, an elderly woman is described in a poem through a play on tsukumogami, written with characters referring to the hair of ninety-nine years. The pronunciation kami can signify hair or, when written differently, a deity or spirit. The similarity gave later writers an opportunity to associate great age with an object capable of acquiring an uncanny life.
Reider’s study of the tale and its wordplay explains that tsukumo could evoke old age without identifying an exact number of years. In the medieval story, owners discard possessions shortly before the hundred-year threshold associated with their transformation. The tools understand the disposal as a deliberate deprivation: after almost reaching the age associated with spiritual power, they have been denied the chance to acquire it.
The tools’ own choices drive their transformation in the Tsukumogami ki. Its discarded characters debate what to do, resolve to change their condition and call on a creation deity at the turning of the year. Their collective anger matters as much as the customary threshold. The narrative connects the transformation to chosen action and a ritual moment, rather than portraying age as a mechanism that operates on its own.
The author situates these events around the Kōhō era, 964–967, in the old capital of Heian-kyō. Those dates belong to the fictional setting. The surviving literary tradition arose much later, in the Muromachi period, when the long-vanished world of the Heian court offered writers a recognizable backdrop for stories about demons, aristocrats and supernatural disturbances.
New Year Cleaning and the Tools’ Revolt
The discarded possessions have been brought into the streets during susuharai, the sweeping away of soot associated with cleaning the house for the New Year. The story explains that people deliberately remove objects approaching a hundred years of age, hoping to prevent them from acquiring troublesome spirits. Householders hope to avert a danger by disposing of the objects. The tools interpret the same act as abandonment.
The objects lie among the rubbish, vulnerable to passing animals and stripped of the purpose that occupied their former lives. Having served loyally for decades, they believe they deserve better treatment. Their meeting turns the grievance into a demand for retaliation. They imagine reversing the authority that allowed owners to command tools and discard them when they were no longer wanted.
Ichiren, a string of Buddhist prayer beads, opposes revenge. He urges the assembled objects to bear their misfortune and respond with goodwill. Aratarō, a club whose name is usually rendered Rough John, attacks him instead, beating him until his cord is nearly severed. The conflict separates Ichiren’s counsel from the group’s growing appetite for violence. Even the injured rosary, carried away by sympathizers, finds anger difficult to master.
The group then hears from Kobun sensei, a scholarly scroll called Professor Classical Chinese Literature. He draws on yin and yang, the alternating principles used to explain change, and advises the objects to wait for setsubun. In this narrative the seasonal boundary falls on the eve of the lunar New Year. At that moment, they are to abandon their existing forms and place themselves in the hands of a creation deity who can transform them.
The personalities follow the objects’ former jobs. A scroll lectures the others on learned cosmology; a club makes his point through blows; prayer beads urge religious mercy. The humor makes the argument recognizable as a human quarrel over loyalty and obligation. These once-silent implements have developed opinions about the treatment they received and about how they ought to respond.
The Night the Discarded Objects Became Monsters
When the chosen night arrives, the tools entrust themselves to the creation deity. They emerge as human figures, foxes, wolves and a variety of frightening creatures. The Kyoto University synopsis of its illustrated scroll recounts the earlier dispute, Ichiren’s beating and the sudden appearance of monsters. Its illustrations turn familiar possessions into figures that readers could recognize and enjoy without knowing the religious teachings behind the story.
Now able to move about, the creatures must find a base. They settle behind Mount Funaoka, northwest of the city, reasoning that a more remote mountain would make food difficult to obtain. Their practical concern becomes grotesque once their diet is revealed. They seize and eat human beings and animals, and reports of their attacks spread fear through the capital.
The monsters’ lives are filled with feasting, dancing, poetry and extravagant boasts. Reider’s translation also preserves the disturbing imagery of flesh and blood that accompanies their revels. Their courtly entertainments recall the behavior of demons elsewhere in medieval storytelling. Objects once used to maintain a household now imitate refined social customs while engaging in acts that threaten the households around them.
Readers may have recognized the legend of Shuten Dōji, a demon lord remembered for a mountain refuge and lavish, violent banquets. Reider points to similarities in the hideouts, feasts and boasts of the two groups. By behaving like the followers of a notorious demon, the transformed tools become threatening figures; the absurdity remains that the terrible revelers were once everyday household possessions.
The former implements also create a religion of their own. They build a shrine to the creator responsible for their new bodies and name him Henge daimyōjin, the Great Shape-Shifting God. Some become ritual officials, and the group stages ceremonies. Their ambitions now extend to the honors and institutions of human society. The monsters seek a stable community with its own religious authority as well as food and freedom from their former masters.
A Night Parade Confronts the Imperial Court
At a spring festival they carry the shrine and its decorations along First Avenue, where their procession crosses that of the imperial regent, one of the court’s most senior officers. His followers panic at the sight of the creatures. The regent himself possesses the Sonshō dhāraṇī, a written protective Buddhist formula. Such a dhāraṇī can be recited or carried in written form as part of religious practice.
The incantation erupts in supernatural fire, throwing the monsters into disorder. The emperor responds by calling on Buddhist specialists. Through their rites appear armed boy guardians known as gohō dōji, who pursue the tool specters to their refuge and overwhelm them. The guardians spare the defeated creatures on the condition that they stop attacking living beings and undertake Buddhist discipline.
The Sonshō dhāraṇī protects the regent, and the priests’ summoned guardians halt the attacks. The creatures that had terrorized the capital are spared only after accepting the Buddhist discipline Ichiren urged before their rebellion. For the tale’s writer, the events make the protective power of the dhāraṇī and the religious instruction of the priests inseparable from the monsters’ eventual repentance.
That festival confrontation cannot be found in identical form in every surviving copy. Reider separates the sixteenth-century Sōfukuji scrolls from a related manuscript group preserved largely in later copies. The latter contains passages about the festival, the regent and the emperor’s response that are missing from the former. The festival confrontation belongs to one version of the story, so it cannot be assumed to have appeared in every medieval copy.
Why the Tool Specters Became Buddhist Monks
The defeated creatures remember the prayer beads they drove away. Ichiren has withdrawn to the mountains, where he has pursued serious Buddhist practice. Seeking a teacher, the tools travel to find him. Aratarō, who almost broke him with a beating, comes face to face with his former victim. Ichiren forgives the club and agrees to instruct the repentant group.
Under Ichiren’s guidance, the objects take monastic vows and ask which Buddhist path will lead them most directly toward awakening. He points them to Shingon, the esoteric Japanese school associated with Kūkai (774–835). Shingon practice employs mantras, ritual hand gestures and visualization, bringing practitioners into relationship with Mahāvairocana, the cosmic Buddha known in Japan as Dainichi. The school’s teachings determine the direction of the rest of the story.
The key teaching is sokushin jōbutsu, commonly translated as the attainment of Buddhahood in this very body. The tale extends the possibility of awakening to objects ordinarily thought to lack sentience. Its former monsters, who have begun religious training while retaining the history of their material lives, give the writer a dramatic means of expressing the doctrine.
The writer even finds a joke in the new students’ physical forms. A vessel holds things, and the reformed vessels are presented as especially well suited to retaining instruction. As Reider’s analysis explains, the play on ki, meaning vessel or capacity, connects the objects’ former uses with their ability to receive religious knowledge. The absurd premise becomes part of the theological explanation.
Ichiren attains Buddhahood before the gathered pupils. The tool monks continue practicing, eventually withdrawing to separate mountain retreats and reaching awakening themselves. The conclusion favors Shingon teachings over explanations in which strange objects merely house demons from outside. In the story’s religious world, even material things can be transformed through the path offered by esoteric Buddhism.
What the Story Says About Old Objects and Disposal
Readers sometimes take the story as a warning against throwing away possessions, yet its owners discard old implements precisely because they fear the consequences of keeping them. The text never consistently rejects New Year cleaning. It condemns the monsters’ retaliatory violence and the resentment that sustains it. Their Buddhist conversion ends the threat while leaving the custom of household renewal intact.
The discarded implements also speak as if years of service had created an obligation. Their former work matters to them, and they resent being dismissed as useless. The complaint borrows the language of loyalty, repayment and injured status from relationships among people. Giving objects a memory of service makes routine disposal into a recognizable social grievance.
Buddhist ceremonies could accompany the retirement of worn-out things. Fabio Rambelli, cited in Reider’s account of the text, connects the work with kuyō, Buddhist memorial or propitiatory rites performed when objects are retired. Through such services, an owner could acknowledge an implement’s use and part with it within a religious framework. The connection places the story alongside the ritual work of Buddhist institutions, as well as the emotions imagined for former household possessions.
These ceremonies could also bring priests support from patrons. Reider suggests that the narrative may have encouraged recourse to Shingon rituals and thereby served institutional interests. That remains a reading of its possible social function. The surviving tale does not show that every family in medieval Japan held formal rites when throwing out old utensils.
Behind the satire lies a Buddhist disagreement about whether plants and other insentient things can attain awakening. Shingon was one participant in that discussion, and other traditions offered their own answers. The Tsukumogami ki takes a particular side by making discarded implements into successful monks. Its comic conversions illustrate the power the author attributed to esoteric practice.
Were There Stories About Living Objects Before Tsukumogami?
Accounts of living or spirit-inhabited objects were already circulating in Japan before the surviving Tsukumogami ki. The early twelfth-century Konjaku monogatarishū tells of a copper vessel whose spirit appears as a human and of an oil pot connected with a sick girl’s death. Neither follows the later plot about tools discarded just before their hundredth year. The first involves a spirit manifesting itself, while the second links a dangerous presence to possession of a vessel.
These earlier accounts describe several different kinds of uncanny objects. An object inhabited by a demon, one that produces a spirit in human shape and one that deliberately transforms itself after abandonment represent different kinds of supernatural events. Reider uses examples from the earlier stories in Konjaku to establish the narrative material available to later writers without collapsing those distinctions.
Another related tradition is the hyakki yagyō, the Night Parade of One Hundred Demons. Stories of encounters with frightening processions are older than the surviving illustrated tool tales. Muromachi artists developed the spectacle into long painted scrolls populated by animal-like creatures, demons, mixtures of imaginary forms and objects that had acquired faces or limbs.
The Night Parade Scrolls and Their Animated Tools
At Shinjuan, a subtemple of Kyoto’s Daitokuji, a sixteenth-century Hyakki yagyō scroll presents one such continuous parade. The University of Chicago’s East Asian Scroll Paintings catalogue lists the paper painting as a Muromachi-period work and gives the traditional attribution to Tosa Mitsunobu. That catalogue attribution should be reported as such; it does not securely identify the individual who painted the surviving work.
The Shinjuan procession does not illustrate the entire Tsukumogami ki. It provides no corresponding account of discarded objects organizing revenge, confronting the emperor and becoming monks. The painted parade shares supernatural imagery with the tale, while the religious instruction and ordered plot belong specifically to the tool-specter narrative.
The relationship may also have encouraged a pun. In Japanese, the characters for demon and vessel can both be pronounced ki. Thus hyakki yagyō, the procession of one hundred demons, could be recast as a procession of a hundred implements. Reider discusses the verbal resemblance while leaving room for artists and writers to have exchanged and adapted visual ideas.
Images of the parade continued to circulate after the Muromachi period. The British Museum’s eighteenth-century handscroll titled Hyakki yagyo provides a later example of the procession. Its catalogue says the work is claimed to be by Hanabusa Itchō, carefully signaling that authorship remains uncertain. Edo-period painters repeatedly arranged the creatures afresh, emphasizing humor, refinement or menace in different versions.
What the Surviving Tsukumogami Scrolls Actually Show
Several illustrated manuscripts preserve the Tsukumogami ki, but no surviving copy can be securely identified as its original. Reider identifies the sixteenth-century Sōfukuji scrolls in Gifu and another group of related witnesses, including later copies. Their differing sequences and expanded episodes are part of the evidence for how the narrative was transmitted, revised and illustrated over time.
A two-scroll Tsukumogami emaki survives in Kyoto University Main Library. The library’s description follows the tools from year-end disposal through revenge to repentance and enlightenment, but identifies its particular manuscript as a later copy of the medieval narrative. Its date as a surviving physical object must therefore be distinguished from the period in which the story first circulated.
The manuscripts preserve both the written narrative and the images through which its characters and religious ideas were conveyed. They cannot tell us how many medieval people believed utensils could literally move and attack their owners. They also provide no permanent standard for a tsukumogami’s appearance: illustrators could alter forms and details as copies of the story were made.
From Medieval Tool Specters to Edo-Period Yōkai Books
Printed yōkai picture books became increasingly prominent during the Edo period, 1603–1868. The artist Toriyama Sekien was especially influential, arranging supernatural figures into illustrated series that readers could recognize individually. An object spirit could now circulate in print as a named creature with a distinctive picture, detached from the complete medieval narrative that may have contributed to its imagery.
Sekien published Hyakki tsurezure bukuro in 1784, a collection particularly relevant to animated implements. A copy is held by the Smithsonian National Museum of Asian Art, and another appears in the catalogue of the British Museum. These surviving woodblock-printed books place the playful representation of object-like yōkai within the established publishing culture of the late eighteenth century.
Later printed creatures do not all descend directly from the Tsukumogami ki. Sekien combined inherited stories with linguistic jokes, literary references and original designs. The inkstone spirit Suzuri no tamashii, for example, appears in his Konjaku hyakki shūi of 1781. Its connection with writing and imagination differs from the medieval account of discarded tools organizing a revolt.
In Edo-period print culture, an animated object could circulate as a recognizable character without the Buddhist purpose assigned to it in the earlier story. Artists used such figures in picture catalogues, and later audiences encountered them in popular entertainment and stories for children. Michael Dylan Foster’s history of yōkai representation examines these changing ways of presenting, naming and classifying Japan’s strange creatures. Their visual continuity should not obscure the changing uses to which they were put.
The familiar umbrella monster is a good example. It is regularly grouped with tsukumogami because it resembles the family of animated objects. The resemblance alone tells us neither whether a particular umbrella spirit appears in the medieval scroll nor whether it was said to come alive after exactly a hundred years. Japanese writers and artists continued to borrow and develop supernatural designs well beyond the period of the original tool story.
Why the Tsukumogami Story Still Matters
The Tsukumogami ki gives thrown-away implements memories of service, resentment at dismissal and a wish to imitate the institutions of human society. Their monstrous freedom leads to more injury rather than a stable community. Their course changes when they seek instruction from Ichiren, the rosary they assaulted for speaking against revenge. Repentance changes the course of a story that began with an argument over discarded possessions.
The ending makes the Shingon teaching explicit: material things ordinarily treated as insentient may still attain Buddhahood. Comedy and violence bring that difficult claim into a story about household objects. A club asks forgiveness, a vessel learns to receive teachings and prayer beads become a revered master. The transformation that matters in the end is the one that follows their decision to abandon revenge.
