In its own language: 百器徒然袋
hyakki joins 'hundred' with 'oni', a demon; here the second character is replaced by one meaning vessel
A 1781 Japanese picture book in which crafted objects wake up as spirits
The fourth of Toriyama Sekien's picture books on yōkai, printed in Japan in 1781. Its punning title, a hundred vessels swapped for a hundred demons, announces a gallery of tsukumogami, made things believed to wake into spirits, many of them the artist's own inventions.
- Fourth and last of Toriyama Sekien's four yōkai picture books, printed in 1781
- Title pun: 'hundred oni' becomes 'hundred vessels', a nod to tsukumogami
- Most creatures are Sekien's own, grown from literary phrases and anecdotes
- Early printings present the book as notes on a strange dream

What it is
Gazu Hyakki Tsurezure Bukuro is a picture book from 1781, the last of four that the Japanese artist Toriyama Sekien devoted to yōkai, the monsters and odd spirits of Japanese story. Each page presents a creature in picture form, gathered into one printed gallery. The title carries a joke: hyakki, which normally spells a hundred oni, or demons, is written here with a character meaning vessel instead. That swap points to the book's favourite monsters, tsukumogami, things made by human hands that are said to have gained a mind and a will of their own. The whole work runs to three slim booklets, and early editions present it as the notes of one strange dream.
Where it comes from
Sekien brought this volume out in 1781 as the closing part of a four-book run that had opened with Gazu Hyakki Yagyō and grown through two later collections. Its deepest debt is literary. Tsurezuregusa, a book of short essays that the monk Yoshida Kenkō set down in the fourteenth century and often rendered in English as Tales in Idleness, supplied subjects and the echo in the title. Where the earlier volumes leaned on older lore, most of the beings here look to be Sekien's own inventions, raised out of phrases and little stories in Kenkō's collection, with more drawn from other writings.
How it is done
This is a book to look at, not a rite to perform. It is divided into three sub-volumes named Jō, Chū and Ge, plain position words in Japanese that English editions usually count as first, second and third. Each booklet carries its own roll of creatures. Printings vary in one respect: the earliest ones open with a short preface that frames the whole work as the jottings of an odd dream, while the third printing drops that introduction altogether.
Tools and materials
The swap in the title is the book's master key. Hyakki ends, as a rule, with the character for oni, a demon; Sekien substitutes the character for a vessel. Readers thus know before opening it that the cast inside will be largely tsukumogami, objects shaped by human craft that are held to have turned into living spirits. Things people have made supply most of the monsters.

What it is for
Nothing here reads as a manual. The book gathers, names and pictures a crowd of spirits, and much of its pleasure lies in spotting the literary game: creatures raised from phrases and small tales in Kenkō's essays and elsewhere. As a bestiary it offers readers a roll call of yōkai rather than charms, blessings or rites, and it makes no claim to heal, harm or foretell.

What people believe
Two strands of Japanese lore hold the book together. One is yōkai: the broad family of strange beings, grotesque or comic, that populate Japanese tales and pictures. The other is the tsukumogami idea, under which an object made by people can pass over into sentience and act as a creature with purposes of its own. Even the old word for a throng of demons, a hundred oni, is bent so that the counted beings become vessels instead. The dream preface in early editions wraps the gallery in a story, as if the artist had merely set down what he saw while asleep.
Compare and confuse
The volume sits at the end of a set of four, and readers sometimes blend it with its siblings. Gazu Hyakki Yagyō, the first, gave the whole series its name. What marks this closing book out are the traits the earlier ones lack: a cast largely of the artist's own devising and a loose dream narrative holding the pages together.
Today
The set still travels. A translation of the entire four-book series, with notes added, was published for English readers in 2016. In Japan, a copy of the third printing is preserved at the National Diet Library of Japan, and pictures from that edition are the ones used when the book is shown.
Questions people ask about Gazu Hyakki Tsurezure Bukuro
What is the Gazu Hyakki Tsurezure Bukuro?
A Japanese picture book printed in 1781, the fourth and final volume in Toriyama Sekien's series on yōkai, the spirits and monsters of Japanese story. It works as an illustrated bestiary, and most of its creatures are tsukumogami, crafted objects said to have turned into living spirits.
Why does the title mention a bag?
The word hyakki normally pairs 'hundred' with the character for oni, a demon. Sekien swaps that second character for one meaning vessel, so the title jokes about a container holding a hundred beings. The swap signals that the monsters inside are mostly made objects rather than demons.
Where do its creatures come from?
Unlike the earlier volumes, most of these beings appear to be Sekien's own inventions. He built them from phrases and small tales in Tsurezuregusa, Yoshida Kenkō's fourteenth-century essay book, and from other writings.
Does the book tell one story?
Barely. Early printings open with a short preface that frames the whole gallery as what the artist saw in a strange dream; the third printing leaves that frame out. Otherwise the material is simply divided into three booklets, counted in English as first, second and third.
Can it be read outside Japan?
Yes. A translation of the complete four-book series, put into English with notes added, came out in 2016. The National Diet Library of Japan preserves a copy of the third printing, and pictures from that edition are the ones usually shown.
