Izanagi

Izanagi 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 Izanagi rather than just read about it. In short: Izanagi (イザナギ/伊邪那岐/伊弉諾; Japanese pronunciation: [ì.(d͡)zä́.nä́.ɡ̟ʲí, -ŋ̟ʲí]), formally referred to with a divine honorific as Izanagi-no-Mikoto (伊邪那岐命/伊弉諾尊; [ì.(d͡)zä́.nä́.ɡ̟ʲí nó̞ mʲí.kó̞.tó̞, -ŋ̟ʲí]; meaning "He-who-invites" or the "Male-who-invites"), is the creator deity (kami) of both creation and life in Japanese mythology. He and his sister-wife Izanami are the last of the seven generations of primordial deit…

Key takeaways

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

Reference excerpt

Izanagi (イザナギ/伊邪那岐/伊弉諾; Japanese pronunciation: [ì.(d͡)zä́.nä́.ɡ̟ʲí, -ŋ̟ʲí]), formally referred to with a divine honorific as Izanagi-no-Mikoto (伊邪那岐命/伊弉諾尊; [ì.(d͡)zä́.nä́.ɡ̟ʲí nó̞ mʲí.kó̞.tó̞, -ŋ̟ʲí]; meaning "He-who-invites" or the "Male-who-invites"), is the creator deity (kami) of both creation and life in Japanese mythology. He and his sister-wife Izanami are the last of the seven generations of primordial deities that manifested after the formation of heaven and earth. Izanagi and Izanami are held to be the creators of the Japanese archipelago and the progenitors of many deities, which include the sun goddess Amaterasu, the moon deity Tsukuyomi, and the storm god Susanoo. He is a god that can be said to be the beginning of the current Japanese imperial family.

Name His name is given in the Kojiki (c. 712 AD) both as Izanagi-no-Kami (伊邪那岐神) and Izanagi-no-Mikoto (伊邪那岐命), while the Nihon Shoki (720 AD) refers to him as Izanagi-no-Mikoto, with the name written in different characters (伊弉諾尊). The names Izanagi and Izanami are often interpreted as being derived from the verb izanau (historical orthography izanafu) or iⁿzanap- from Western Old Japanese 'to invite', with -ki / -gi and -mi being taken as masculine and feminine suffixes, respectively. The literal translation of Iⁿzanaŋgî and Iⁿzanamî are 'Male-who-invites' and 'Female-who-invites'. Shiratori Kurakichi proposed an alternative theory which instead sees the root iza- (or rather isa-) to be derived from isao (historical orthography: isawo) meaning 'achievement' or 'merit'. The etymological origin of the verb is suggested to be a precursor to the Middle Korean lemma yènc- meaning 'to place/put on [the top of]' reconstructed as *yenc-a (place-INF) in Old Korean.

Mythology

In the Kojiki

The birth of the land

The Kojiki portrays Izanagi and his younger twin sister Izanami as the seventh and final generation of deities that manifested after the emergence of the first group of gods, the Kotoamatsukami, when heaven and Earth came into existence. Receiving a command from the other gods to solidify and shape the Earth (which then "[resembled] floating oil and [drifted] like a jellyfish"), the couple use a jewelled spear to churn the watery chaos. The brine that dripped from the tip of the spear congealed and turned into an island named Onogoro (淤能碁呂島). The two descended to the island and, setting up their dwelling, erected a 'heavenly pillar' (ama no mihashira) on it. Izanagi and Izanami, realizing that they were meant to procreate and have children, then devised a marriage ceremony whereby they would walk in opposite directions around the pillar, greet each other and initiate intercourse. After Izanami greeted Izanagi first, Izanagi objected that he, the man, should have been the first to speak. True enough, the first offspring that resulted from their union, the 'leech-child' Hiruko, was considered imperfect and set adrift on a boat of reeds. Izanagi and Izanami then also begat the island of Awa (淡島 Awashima), but this too was not counted among their rightful progeny.

Izanagi and Izanami then decided to repeat the ritual, with Izanagi greeting Izanami first. This time, their union was a success, with Izanami giving birth to some of the various islands that comprise the Japanese archipelago (with the notable exceptions of Shikoku and Hokkaido), which include the following eight islands (in the following order):

Awaji-no-Ho-no-Sawake (淡道之穂之狭別島) The double-named island of Iyo (伊予之二名島 Iyo-no-Futana-no-Shima, modern Shikoku) The triple islands of Oki (隠伎之三子島 Oki-no-Mitsugo-no-Shima) Tsukushi (筑紫島, modern Kyushu) Iki (伊伎島) Tsushima (津島) Sado (佐度島) Ōyamato-Toyoakitsushima (大倭豊秋津島, modern Honshu) The two then proceeded to beget the various deities who are to inhabit these lands. Izanami, however, was badly injured and eventually died after giving birth to the fire god Kagutsuchi. In an act of grief and rage, Izanagi killed Kagutsuchi with his 'ten-grasp sword'. More gods manifest into existence out of Izanami's excreta, Kagutsuchi's blood and mutilated remains, and Izanagi's tears.

Descent into Yomi Izanagi, wishing to see Izanami again, went down to Yomi, the land of the dead, in the hopes of retrieving her. Izanami reveals that she had already partaken of food cooked in the furnace of the underworld, rendering her return impossible. Izanagi, losing his patience, betrayed his promise not to look at her and lit up a fire, only to find that Izanami is now a rotting corpse, causing him to run away in terror. To avenge her shame, Izanami dispatched the gods of thunder (known as the Yakusanoikazuchi), the "hags of Yomi" (予母都志許売 Yomotsu-shikome), and a horde of warriors to chase after him. To distract them, Izanagi threw the vine securing his hair and the comb on his right hair-knot, which turned into grapes and bamboo shoots that the hags devoured. Upon reaching the pass of Yomotsu Hirasaka (黄泉比良坂, the 'Flat Slope of Yomi'), Izanagi took three peaches from a nearby tree and repelled his pursuers using them. He then declared the peach fruit to be divine, naming them Ōkamuzumi, and bade it to grow in the land of the living to help people in need, just as it had helped him. When Izanami herself came in pursuit of him, Izanagi sealed the entrance to Yomi using a huge boulder, which itself became a deity, known as Yomido ni Sayarimasu no Ōkami, or by the alternate name Chigaeshi no Kami recorded in both the Kojiki and the Nihon Shoki, since worshipped as a guardian deity of roads and borders (sai no kami). Izanami then pronounced a curse, vowing to kill a thousand people each day, to which Izanagi replies that he would then beget a thousand and five hundred people everyday to thwart her.

Purification (Misogi)

Izanagi, feeling contaminated by his visit to Yomi, went to "[the plain of] Awagihara (i.e. a plain covered with awagi) by the river-mouth of Tachibana in Himuka in [the island of] Tsukushi" and purified himself by bathing in the river; various deities came into existence as he stripped off his clothes and accouterments and immersed himself in the water. The three most important kami, the "Three Precious Children" (三貴子 mihashira no uzu no miko or sankishi) – the sun goddess Amaterasu Ōmikami, the moon deity Tsukuyomi-no-Mikoto, and the storm god Susanoo-no-Mikoto – were born when Izanagi washed his left eye, his right eye, and his nose, respectively.

Worked examples

Example 1 — a first encounter with Izanagi

Start with the simplest possible case. Write down what Izanagi 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 Izanagi 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 Izanagi 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 Izanagi

In research
Izanagi 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 Izanagi 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
Izanagi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amatsukami, Creation myths, Creator gods, so understanding it makes those chapters shorter.
In everyday life
Look for Izanagi 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.
