Tsukumogami: When Old Tools Wake, and the Hundred-Year Claim Checked

At the end of the year a household sweeps the soot from its rafters and carries old things out to the lane: a worn rosary, a scroll nobody reads. Then comes the night before spring, and the things in the lane begin to move.

That is the opening of a medieval Japanese tale about the tsukumogami, objects that wake and take revenge on the people who threw them away. The story is vivid, and it comes with a number attached: one hundred years. This page checks where that number comes from, who wrote the tale and why, and how much is known about any belief behind it.

The tale that names them

The key text is Tsukumogami ki, which Noriko Reider translates as "Record of tool specters." It is a companion tale (otogizoshi) of the Muromachi period, 1336 to 1573, a kind of short story written for both amusement and religious teaching. Reider, writing in the Japanese Journal of Religious Studies in 2009, calls it entertaining and argues that its authors mainly wanted to spread Shingon Buddhist teaching.

The plot is simple. During the year-end house-cleaning, set in the Heian capital of the late tenth century, old tools are dumped in the alleys. They resent it. With the help of a creation god they transform on the eve of spring, then kidnap people and celebrate with wine, gambling and poetry. In the end, with imperial and Buddhist support, the spirits repent, enter religious life and reach buddhahood through Shingon practice.

The tale survives in several manuscripts. Reider names one scroll of the first type, at Sofukuji in Gifu Prefecture, dated to the sixteenth century. The other versions she lists are Edo-period scrolls, held by libraries and museums. The National Diet Library also holds a copy of the picture scroll, which it calls Tsukumogami-e.

The hundred years, checked

The tale says that tools gain a spirit after a hundred years. Here is what the claim rests on.

So the hundred years is a storytelling number. It is honest to say the tale uses it, and honest to say its stated authority is shaky. Notice too that the tale ties the custom of renewing things at the New Year to avoiding the calamity of tsukumogami. The sweeping and the spirits are linked in the story's own words.

Night parades of tools

From the Muromachi period on, picture scrolls called Hyakki Yagyo Emaki show a night parade of demons. Reider says many are generally considered portrayals of the festival procession in Tsukumogami ki, though other scholars read them as parodies of earlier Heian accounts of demon parades. The National Diet Library's picture scroll shows a crowd of creatures filing through the streets of Kyoto, most of them tsukumogami, everyday tools and utensils come to life. The library gives no date for that scroll.

Reider also points to a pun. The sound ki can mean a vessel or tool, and it can mean a demon. So the night procession of a hundred demons can be read as the night procession of a hundred tools.

In 1784, according to the Library's dating, Toriyama Sekien published Hyakki Tsurezure Bukuro, with pictures of a biwa, a koto and a kettle that have turned into yokai. The Library's column says the earlier scrolls clearly influenced him.

Belief, literature and practice today

Scholars disagree about how much living belief stood behind the tale. Reider cites Komatsu Kazuhiko as suggesting that people before the modern age probably did believe in the spirits of tools, though Reider adds that he gives no concrete examples. English Wikipedia also cites Komatsu for the view that late-Edo art revived the idea after actual belief had faded. Both readings come from the same scholar in different works, so we would not call the question settled.

Reider adds that one Sofukuji passage promises long life to those who put away old things at year-end, and she reads the text as encouraging memorial services for discarded goods, following the scholar Rambelli. That is a scholar's interpretation, not a plain fact about medieval practice.

Today some temples hold memorial services for tools. The Sensoji temple in Asakusa, on its own website, describes a needle memorial on 8 February: people push old needles into soft tofu, give thanks for them and pray for skill at sewing. The temple says such services are held nationwide, centered on shrines and halls of the deity Awashima. My sources do not show that this practice grew from the tsukumogami scrolls, so we mention it only as a living custom of thanking old tools.

How to read a tsukumogami claim

1. Ask whether it comes from the tale, from a picture, or from a modern summary.
2. Check what number of years is given, and whether the source calls it exact.
3. Look for what happens to the tools: revenge, repentance, or helpfulness. Reider notes that in eighteenth-century comic books the tool specters are often little helpers, and the scholar Adam Kabat suggests they should perhaps not be called tsukumogami at all.
4. Look for a date and a manuscript, not only a famous title.

Common mistakes and mix-ups

• "Exactly ninety-nine years." The sources treat the number as figurative.
• "Only tools." The word was also applied to old foxes and tanuki, as in the case of Kitsune and Tanuki, and Reider notes the aged fox of the tale of Tamamo-no-Mae.
• "A record of folk belief." Tsukumogami ki is a literary tale with a religious purpose, not a field report.
• "The night parade scroll is the same work." The parade scrolls and the tale are related, but they are different works.
• "It is worshipped." In one version of the tale the spirits themselves worship a creation god with a frivolous name, and then convert to Buddhism. No source we read describes worship of tsukumogami today.
