Kuda-gitsune

Kuda-gitsune is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kuda-gitsune rather than just read about it. In short: The kuda-gitsune or kuda-kitsune (管狐, クダ狐), also pronounced kanko, is a type of spirit possession in legends around various parts of Japan. It may be known otherwise as osaki especially in the Kantō region, and also considered equivalent to the izuna.

Key takeaways

  • Kuda-gitsune belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kuda-gitsune to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kuda-gitsune from memory before moving on to harder problems.

Reference excerpt

The kuda-gitsune or kuda-kitsune (管狐, クダ狐), also pronounced kanko, is a type of spirit possession in legends around various parts of Japan. It may be known otherwise as osaki especially in the Kantō region, and also considered equivalent to the izuna. It was believed to assume the guise of a small mammal and able to fit inside a pipe or bamboo tube, but normally only its keeper or user (kitsune-tsukai) was able to see it. The user, through the power of the kuda, was believed capable of divulging a person's past or foretelling his future; this soothsayer was also capable of performing curses, bringing calamity upon targets. In regions where the superstition was held, a prospering household could be accused of achieving its prosperity because it was a house possessed by the spirit (kuda-tsuki). The fox (and its analogues by other names) was said to multiply in number each time a marriage took place, following the bride to her place of marriage, thus disseminating into more households.

Nomenclature The kuda-gitsune or kuda-kitsune (管狐, クダ狐), which in Chinese fashion (onyomi) can also be read as kanko (old romanization kwanko), derives its name from being small enough to fit inside a tube, according to one explanation. It may also have earned its name due to its tail resembling a tube spliced in two. Folklorist Yanagita Kunio conjectured that the kuda alluded to a god's descent (verb: kudaru) from the mountain, this god Ta-no-Kami ("rice paddy god") being roughly equated with the Yama-no-Kami or "mountain god".

Aliases The izuna (飯綱) is a kindred sort of spirit, employed by the "fox-user" or kitsune-tsukai (狐遣い), (although in modern standard Japanese, the word is pronounced īzuna and denotes the least weasel). The osaki fox is also identified as an equivalent spirit employed by the "fox-user" (kitsune tsukai). According to one summarization, the term kuda-gitsune (クダ狐) is prevalent in the Central region (Chūbu region), whereas the appellation izuna tends to be used in north-central Nagano and the northeast (Tōhoku), and osaki in the northern Kantō region.

Geography The kuda-gitsune lore has traditionally been found in Shinano Province (present-day Nagano Prefecture, in the northern Central Region) and has been associated with the Iizuna gongen, the deity of Mount Iizuna in the area of Togakushi or the Iizuna or Izuna ritual (Izuna no hō (飯綱の法), practiced in shugendō) based on its worship (cf. §Izuna below). The kuda-gitsune also occurred in the folk-belief of more southerly portions of the Central Region known as the Tōkai subregion, namely Mikawa (in present-day Aichi) and Tōtomi Provinces (present-day Shizuoka Prefecture). It also forms part of the folklore in the southern Kantō region, Tōhoku region, and elsewhere. There are no legends of kuda-gitsune in Kantō besides the Chiba Prefecture and Kanagawa Prefecture, and this is said to be because Kantō is the domain of the osaki fox tradition. Despite the localizations above, the ability of using the kanko/kudagitsune is purportedly obtained by trained yamabushi (the ascetics of shugendō) at their holiest sites, either Mount Kinpu or Mount Ōmine (in present-day Nara Prefecture), according to Asakawa Zen'an who wrote the essay Zen'an zuihitsu.

General description According to some sources the kuda-gitsune ("pipe fox" or "tube fox") is kept inside a bamboo tube, especially by the yamabushi. The fox in the bamboo tube may be summoned by reciting a magical incantation, and be made to answer any questions asked. Alternatively it is said that fox user (kitsune-tsukai) keeps the tamed kuda fox spirit in the bosom of his garment ("pocket") or up his sleeve, and the creature collects assorted information which it whispers to its master's ear, so that the practitioner of the art may then reveal another's history, or predict another's future. The spirit remains invisible, and can be only seen by the user. As for its size, the Edo Period essay collection Kasshi yawa (1841) by Matsura Seizan has an entry on the kuda-gitsune, including an illustration (above) of the fox said to have been brought from a bucolic area in Osaka and exhibited in Edo in the year Bunsei 5 (1822), reporting the full length of the specimen (excluding the tail) at 1.2–1.3 shaku (36–39 cm). Yanagita Kunio was of the opinion however that this size represented the largest of this kind, as smaller ones were about the size of a polecat (itachi, <30 cm?). Other sources have described the smallness of the kuda-gitsune by comparing it to the size of a house mouse, or the size of a matchbox. The Shōzan chomon kishū (想山著聞奇集) (1850) also provided visual illustration of a specific anecdotal example, which reportedly had a catlike face, otter-like body, gray-colored fur, and was about the size of a squirrel, with a thick tail. And according to Asakawa Zen'an's essay collection Zen'an zuihitsu (善庵随筆) (pub. 1850), the kanko/kuda-gitsune is about the size of a weasel (itachi) with vertical eyes, but otherwise the same as a feral rat (or perhaps rather the yako), except its thick fur is not all matted/dissheveled.

Izuna An izuna is a fox servant, employed by certain "sorcerers" called izuna-tsukai (izuna users) in the Shinano Region (Nagano Prefecture); these familiars may also be employed by other psychic type religious or spiritual professionals in Niigata Prefecture and other parts of the Northeast, as well as in the Chūbu region, and those who profess to have special powers claim to perform clairvoyancy with the use of the izuna. The sorcerer was also believed capable of harming his client's enemies using the izuna, causing them to become possessed or to fall ill. The izuna is considered by some believers to be a servant of the deity called the Izuna gongen or Īzuna gongen, typically represented as a tengu standing on a white fox. Therefore, the sorcerer (izuna-tsukai) sometimes may be a worshipper of this particular gongen deity, however, that is not always the case.

Worked examples

Example 1 — a first encounter with Kuda-gitsune

Start with the simplest possible case. Write down what Kuda-gitsune claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kuda-gitsune before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kuda-gitsune ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kuda-gitsune

In research
Kuda-gitsune appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kuda-gitsune in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kuda-gitsune is common in secondary-school and first-year university syllabi. It links to neighbouring topics Familiars, Kitsune (fox), Legendary mammals, so understanding it makes those chapters shorter.
In everyday life
Look for Kuda-gitsune outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
