Kami

• 1. Introduction

  ›

  Kami are the divine beings, spirits, and natural phenomena at the heart of Japan's traditional Shinto religion. They can be a mountain, a waterfall, a fox, the rumble of thunder, or the spirit of a beloved ancestor. At the Yasukuni Shrine in Tokyo alone, over 2,446,000 individual kami are enshrined. That staggering figure hints at something vast and restless: a religious tradition in which the sacred is not confined to temples or texts, but woven into every corner of the living world.

  What exactly is a kami? The word has been used to describe a deity, a principle, a ghost, a supreme being, and anything that is worshipped. Even Shinto scholars disagree on the best translation. The question of what kami are, where they come from, and how people have lived in relationship with them for well over a thousand years sits at the center of everything that follows.

• 2. Naming the Unnameable

  ›

  Motoori Norinaga, in his Kojiki-den, offered one of the most direct definitions ever attempted: "any being whatsoever which possesses some eminent quality out of the ordinary, and is awe-inspiring, is called kami." That formulation leaves the door wide open, and deliberately so.

  The kanji character used to write kami, 神, carries a Sino-Japanese reading of shin or jin, and in Chinese it means deity or spirit. The relationship between the Japanese word and its neighbors is contested. John Batchelor argued the word derives from Ainu roots, pointing to the Ainu concept of kamuy, an animistic idea very similar to the Japanese one. Japanese sources, by contrast, point to a Japonic origin. The debate has not been resolved.

  Japanese grammar adds another layer of ambiguity. Nouns in Japanese do not normally distinguish singular from plural forms, so the word kami can refer to one spirit or many at once. When a speaker needs to make a singular meaning clear, a suffix is added. The reduplicated form kamigami is the standard way to signal a multitude. That grammatical flexibility matches the concept itself: kami resist being pinned to a single count, a single shape, or a single meaning.

• 3. Two Souls, Five Traits

  ›

  The Kojiki, Records of Ancient Matters, was written in 712 CE and contains the earliest surviving record of Japanese creation myths, as well as descriptions of various kami. The Nihon Shoki, Chronicles of Japan, followed in 720 CE. Together, these two texts form the oldest written foundation for Shinto belief.

  Ancient tradition identified five defining characteristics shared by all kami. First, kami are of two minds: they can nurture and love when respected, or cause destruction when disregarded. Traditionally each kami possesses two souls, one gentle called nigi-mitama and one assertive called ara-mitama. In Yamakage Shinto, a stream known as Ko-Shinto, two additional hidden souls are recognized: one happy, saki-mitama, and one mysterious, kushi-mitama.

  Second, kami are not visible to humans. They inhabit sacred places, natural phenomena, or people during rituals that ask for their blessing. Third, they are mobile, visiting their shrines without ever settling permanently. Fourth, there are many varieties: the Kojiki alone lists 300 different classifications, covering everything from the kami of wind to the kami of entryways to the kami of roads. Fifth, every kami carries a specific duty. Just as worshippers are obligated to keep kami content, each kami is obligated to perform the function belonging to the place or idea it inhabits.

• 4. From Harvest to History

  ›

  The earliest roles of kami were earthbound. Hunter-gatherer communities in ancient Japan venerated spirits of mountains and the sea. As rice cultivation grew in importance, the kami's identities shifted toward rain, earth, and rice, the forces that determined whether harvests succeeded or failed. The rituals developed to entreat these kami became symbols of authority for the early emperors.

  One prominent myth shows that connection directly. When the Sun Goddess Amaterasu sent her grandson to earth to rule, she gave him five rice grains grown in Takamagahara, the fields of heaven. Those grains made it possible for him to transform what the myth calls the "wilderness."

  Social and political upheaval gave rise to a different kind of kami: the goryō-shin, the sacred spirit kami of the vengeful dead. Goryō are spirits of people whose lives were cut short. Through the devotion of Shinto followers, these spirits were calmed, and they came to be understood as powers that punish those who fail to honor the kami.

  The domains of kami expanded as the needs of society changed. The kami of smallpox, for instance, eventually took on responsibility for all contagious diseases. The kami of boils and growths came to preside over cancers and cancer treatments. In 927 CE, a formal codification of Shinto rites and norito, the liturgies and prayers, was promulgated in fifty volumes. It recorded all 2,861 Shinto shrines then in existence and named 3,131 officially recognized and enshrined kami.

• 5. Amatsukami and Kunitsukami

  ›

  Amatsukami and Kunitsukami represent two broad categories that organize the Japanese mythological pantheon. Amatsukami, sometimes written Amatsugami, are the gods of Takamagahara, the heavenly realm, or those descended from the event called Tenson kōrin. Kunitsukami, sometimes written Kunitsugami, are the gods who appeared on earth, in the realm called Ashihara no Nakatsukuni.

  The Nihon Shoki describes a mythological event called kuni-yuzuri, in which the Kunitsukami transferred control of the land to the Amatsu deities led by Ninigi-no-Mikoto. Scholars believe the pattern reflected something political: the deities worshipped by peoples pacified by the Yamato Kingship, including the Emishi and the Hayato, became Kunitsukami. The gods favored by the imperial family and its powerful clans became Amatsukami.

  Susanoo-no-Mikoto, cast out of Takamagahara, and his descendants including Ōkuninushi, are counted among the Kunitsukami. When many Kunitsukami traditions were incorporated into the Nihon Shoki, many original versions did not survive. The Chronicles do preserve references to earlier sources, such as notes labeled "Ichi Sho Saying" and "Aru Hon Yun," but the original documents themselves have been lost.

  The four-character idiom Tenchi-Shinmei, meaning the gods of heaven and earth, draws on both categories. Used in expressions of solemn oath, it traces back to ancient Chinese classical texts where the terms for heaven-earth and gods-brightness were combined. In Japan, the phrase has carried a sense of reverence and commitment for centuries.

• 6. Living with the Kami

  ›

  One of the first recorded rituals involving kami is a ceremony in which the emperor of Japan offers newly harvested rice to secure their blessing. A yearly festival, Niiname-sai, is observed, and when a new emperor comes to power it takes on the special name Daijō-sai. The emperor presents rice, fish, fruits, soup, and stew, feasting first with the deities and then with the guests. Emperor Shōwa's version of the feast spanned two days.

  Visitors to Shinto shrines follow a precise sequence before approaching a kami. They wash their hands, then swallow and spit a small amount of water to purify body, heart, and mind. They bow twice, clap twice, and bow again to attract the kami's attention. During the final bow, worshippers offer gratitude and praise; if praying for help, they also state their name and address. After prayer, the sequence of two bows, two claps, and a final bow is repeated.

  At home, practitioners worship at a kamidana, a household shrine, where an ofuda bearing the name of their protector or ancestral kami is placed. Priests, or kannushi, are specialists in maintaining the connection between kami and people. They are not expected to live as ascetics or to meditate; it is common for them to be married. Some shrines have drawn their priests from the same families for over a hundred generations. The priesthood may include female priestesses, and priests may be assisted by miko, young unmarried women serving as shrine maidens.

  The Shichi-Go-San, the Seven-Five-Three ceremony, marks a rite of passage for five-year-old boys and three- or seven-year-old girls, giving children the chance to personally offer thanks for the kami's protection and to pray for continued health. At the Tsubaki Grand Shrine, high priest Yamamoto Guji describes the festival as the moment when "the greatest celebration of life can be seen in the world of Shinto," carried out by whole communities seeking to realize their potential as children of kami.

• 7. Notable Figures in the Pantheon

  ›

  Amaterasu Ōmikami, the sun goddess, is the chief deity of the Shinto pantheon. In the myths surrounding her, she could observe events in the human world but still had to rely on divination rituals to see the future, a reminder that even the greatest kami are not omniscient or omnipotent.

  Sugawara no Michizane, who lived from 845 to 903 CE, became the kami known as Tenjin after his death, serving as the deity of poetry. His story illustrates the path by which exceptional human beings could be recognized as kami following death: not because of supernatural power, but because of a distinctive quality or virtue they embodied in life. Miniature shrines called hokora have been built in honor of such regionally celebrated kami.

  Other named kami in the tradition include Inari Ōkami, the god of rice and agriculture; Hachiman, the tutelary god of war; Fūjin, the god of wind; Raijin, the god of lightning, thunder, and storms; and Ryūjin, the dragon god of sea and storms. Ebisu is counted among the seven gods of fortune. Izanagi-no-Mikoto and Izanami-no-Mikoto are recognized as the first man and first woman. Kotoamatsukami constitute the primary kami trinity. The tradition also makes room for Omoikane, the deity of wisdom, and Sarutahiko Ōkami, the kami of earth, reflecting the breadth of domains over which kami preside.
