Ninigi-no-Mikoto

Ninigi-no-Mikoto 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 Ninigi-no-Mikoto rather than just read about it. In short: Ninigi (瓊瓊杵) or Ninigi-no-Mikoto (瓊瓊杵尊), is a god in Japanese mythology. (no-Mikoto here is an honorific title applied to the names of Japanese gods; Ninigi is the specific god's name.) Grandson of the sun goddess Amaterasu, Ninigi is regarded according to Japanese mythology as the great-grandfather of Japan’s first emperor, Emperor Jimmu.

Key takeaways

  • Ninigi-no-Mikoto belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ninigi-no-Mikoto to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ninigi-no-Mikoto from memory before moving on to harder problems.

Reference excerpt

Ninigi (瓊瓊杵) or Ninigi-no-Mikoto (瓊瓊杵尊), is a god in Japanese mythology. (no-Mikoto here is an honorific title applied to the names of Japanese gods; Ninigi is the specific god's name.) Grandson of the sun goddess Amaterasu, Ninigi is regarded according to Japanese mythology as the great-grandfather of Japan’s first emperor, Emperor Jimmu. The three sacred treasures brought with Ninigi from Heaven and divine ancestry established the Japanese Imperial Family. The Encyclopedia of Shinto states that the three generations of kami starting with Ninigi are sometimes referred to as the Three Generations of Hyūga: they are said to represent a transitional period between the heavenly kami and the first emperor.

Name and etymology Ninigi-no-Mikoto (瓊瓊杵尊) means "The Great God Ninigi". Another name of his is Ame-nigishi-kuni-nigishi-amatsuhiko-hiko-ho-no-ninigi-no-Mikoto (天邇岐志国邇岐志天津日高日子番能邇邇芸命) or "The Great God Ninigi, of the Imperial State, The Child of the Sun of Many Talents". Ninigi is speculated to be translated as "beloved jeweled mallet".

Myths

Birth Ninigi was born from Ame no Oshihomimi and Takuhadachijihime. Takamimusubi treated him with special affection and nurtured him with great regard.

Sent to rule Depending on the version Amaterasu sends Ninigi to rule either after his father refuses the offer, after several failures, or to replace Ōkuninushi after his troubled rule.

In many stories, Ninigi receives three gifts. The sword Kusanagi no Tsurugi, the mirror Yata no Kagami, and the jewel Yasakani no Magatama.

Descent to earth

Ninigi's descent to earth appears in both the Nihon Shoki and the Kojiki. In an earlier version of the Nihon Shoki Ninigi descends to earth unaccompanied.

But in a later version of the Nihon Shoki and the Kojiki, other gods accompany Ninigi’s journey to earth; who accompanies him and how many depends on the version. But it usually includes the following gods: Uzume, Sarutahiko, Koyane, Futodama, Ishikoridome, and Tamanooya; many of these deities would later become the ancestors of many clans like Sarume clan, Nakatomi clan, Shinabe clan, and Inbe clan.

Ninigi tries to go to earth but he is blocked by Sarutahiko. Uzume then persuades Sarutahiko to let Ninigi pass. In most versions Ninigi descends to earth on Mt. Takachiho in the Kirishima Mountains of Kyushu.

Loss of immortality One story involves Ninigi looking for a wife; he meets the mountain god Oyamatsumi, Oyamatsumi presents Ninigi his two daughters Sakuyahime and Iwanagahime. However, Ninigi accepts Sakuyahime but rejects Iwanagahime due to her ugliness and is cursed for rejecting her. According to the Kojiki, Ōyamatsumi explained that he had offered both daughters together as a pledge that the emperors' lives would be eternal like rock, embodied by the elder sister Iwanagahime ("Princess of the Rock"); but because she had been sent back, the emperors' lives would from then on be as fleeting as the blossoms of flowering trees, embodied by Sakuyahime. The Nihon Shoki instead attributes the outcome to a curse pronounced by Iwanagahime herself, embarrassed at having been rejected, dooming the emperors and all other beings to lives as transient as a blossoming tree; in later tradition, Iwanagahime herself came to be venerated as a tutelary deity of longevity. Going forward, he and his descendants would live shorter lives from now on.

Birth of Ninigi’s children Soon after Ninigi and Sakuyahime got married, Sakuyahime got pregnant in just one night. Ninigi accused his wife Sakuyahime of adultery. In many versions his wife Sakuyahime decided to go in to a hut and set the hut on fire to prove that she was a faithful wife. Sakuyahime and her sons survived, she gave birth to three sons named Hoderi, Hosusero, and Hoori. One variation says that Sakuyahime gave birth to Hoderi in the hut and had the other two sons later.

Death

Later on, Ninigi died and was buried at E no Goriyo. The Nihon Shoki describes his burial place as "Hyūga no Enoyama no misasagi." Although several sites in southern Kyushu have historically been associated with this location, the Imperial Household Agency currently designates Nitta Shrine in Satsumasendai, Kagoshima Prefecture as Ninigi's official burial site; the shrine came under the agency's direct administration in 1914.

Family

Many versions have Amaterasu and Takamimusubi as Ninigi's grandparents, and the son of Ame no Oshihomimi and Yorozuhatahime as his parents. Ninigi is said to be the nephew to Futodama and Ame no Koyane. Ninigi is in the Three generations of Hyuga, a time period between Tenson kōrin and Jimmu's Eastern Expedition.

Worship of Ninigi

Shrines Ninigi has very few temples where he is enshrined. Shrines like Amatsu Shrine and Kirishima-jingu Shrine are dedicated to Ninigi. At Ise shrine, Ninigi is said to be worshipped along with Kuni no Tokotachi.

Worked examples

Example 1 — a first encounter with Ninigi-no-Mikoto

Start with the simplest possible case. Write down what Ninigi-no-Mikoto 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 Ninigi-no-Mikoto 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 Ninigi-no-Mikoto 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 Ninigi-no-Mikoto

In research
Ninigi-no-Mikoto 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 Ninigi-no-Mikoto 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
Ninigi-no-Mikoto is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amatsukami, Japanese gods, Legendary progenitors, so understanding it makes those chapters shorter.
In everyday life
Look for Ninigi-no-Mikoto 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.
