Japanese mythology embraces Shinto and Buddhist traditions as well as agriculturally-based folk religion. The Shinto pantheon comprises innumerable kami (Japanese for "god(s)" or "spirits"). This article will discuss only the typical elements present in Asian mythology, such as cosmogony, important deities, and the best-known Japanese stories.
Japanese myths, as generally recognized in the mainstream today, are based on the Kojiki, the Nihon Shoki, and some complementary books. The Kojiki, or "Record of Ancient Matters", is the oldest surviving account of Japan's myths, legends and history. The Shint?sh? describes the origins of Japanese deities from a Buddhist perspective, while the Hotsuma Tsutae records a substantially different version of the mythology.
One notable feature of Japanese mythology is its explanation of the origin of the Imperial Family, which has been used historically to assign godhood to the imperial line. The title of the Emperor of Japan, tenn? (), means "heavenly sovereign".
Note that Japanese is not transliterated consistently across all sources (see spelling of proper nouns).
The first two generations are individual deities called hitorigami, while the five that followed came into being as male/female pairs of kami: brothers and sisters that were also married couples. In this chronicle, the Kamiyonanayo comprise 12 deities in total.
In contrast, the Nihon Shoki states that the Kamiyonanayo group was the first to appear after the creation of the universe, as opposed to the Kamiyonanayo appearing after the formation of heaven and earth. It also states that the first three generations of deities are hitorigami (individual deities) and that the later generations of deities are pairs of the opposite gender, as compared to the Kojiki's two generations of hitorigami.
The seventh and last generation of Kamiyonanayo were Izanagi no Mikoto ("Exalted Male") and Izanami no Mikoto ("Exalted Female"), and they would be responsible for the creation of the Japanese archipelago and would engender other deities.
To help them to achieve this, Izanagi and Izanami were given a naginata decorated with jewels, named Ame-no-nuboko ("Heavenly Jeweled Spear"). The two deities then went to the bridge between heaven and earth, Amenoukihashi ("Floating Bridge of Heaven") and churned the sea below with the halberd. Drops of salty water formed the island, Onogoro ("self-forming"). The deities descended from the bridge of heaven and made their home on the island. Eventually, they fell in love and wished to mate. So they built a pillar named Amenomihashira around which they built a palace called Yashirodono ("the hall whose area is 8 arms' length squared"). Izanagi and Izanami circled the pillar in opposite directions, and when they met on the other side, Izanami, the female deity, spoke first in greeting. Izanagi didn't think that this was proper, but they mated anyway. They had two children, Hiruko ("leech child") and Awashima ("pale island"), but the children were badly formed and are not considered gods in their original form. (Hiruko later became the Japanese god, Ebisu.)
The parents, who were dismayed at their misfortune, put the children into a boat and sent them to sea, and then petitioned the other gods for an answer about what they had done wrong. They were informed that Izanami's lack of manners was the reason for the defective births: a woman should never speak prior to a man; the male deity should have spoken first in greeting during the ceremony. So Izanagi and Izanami went around the pillar again, and this time, when they met, Izanagi spoke first. Their next union was successful.
From their union were born the ?yashima, or the eight great islands of Japan:
Izanami died giving birth to Kagutsuchi (incarnation of fire), also called Homusubi (causer of fire) due to severe burns. She was then buried on Mount Hiba, at the border of the old provinces of Izumo and Hoki, near modern-day Yasugi of Shimane Prefecture. In anger, Izanagi killed Kagutsuchi. His death also created dozens of deities.

Izanagi lamented the death of Izanami and undertook a journey to Yomi ("the shadowy land of the dead"). Izanagi found little difference between Yomi and the land above, except for the eternal darkness. However, this suffocating darkness was enough to make him ache for light and life. Quickly, he searched for Izanami and found her. At first, Izanagi could not see her for she was well hidden in the shadows. Nevertheless, he asked her to return with him. Izanami spat at Izanagi and informed him that he was too late. She had already eaten the food of the underworld and now belonged to the land of the dead.
Izanagi was shocked at this news, but he refused to give in to her wishes to be left to the dark embrace of Yomi. Izanami agreed to return to the world but first requested to have some time to rest. She instructed Izanagi to not come into her bedroom. After a long wait, Izanami did not come out of her bedroom, and Izanagi was worried. While Izanami was sleeping, he took the comb that bound his long hair and set it alight as a torch. Under the sudden burst of light, he saw the horrid form of the once beautiful and graceful Izanami. The flesh of her ravaged body was rotting and was overrun with maggots and foul creatures.
Crying out loud, Izanagi could no longer control his fear and started to run, intending to return to the living and to abandon his death-ridden wife. Izanami woke up shrieking and indignant and chased after him. Izanami instructed the shikome, or foul women, hunt for the frightened Izanagi and to bring him back.
Izanagi, thinking quickly, hurled his headdress, which became a bunch of black grapes. The shikome fell on these but continued pursuit. Next, Izanagi threw his comb, which became a clump of bamboo shoots. Now it was Yomi's creatures that began to give chase, but Izanagi urinated against a tree and created a great river that increased his lead. Unfortunately, the shikome still pursued Izanagi, who began to hurl peaches at them. He knew that this would not delay them for long, but he was nearly free, for the boundary of Yomi was now close at hand.
Izanagi burst through the entrance and quickly pushed a boulder to the entrance of Yomi. Izanami screamed from behind this barricade and told Izanagi that, if he left her, she would destroy 1,000 living people every day. He furiously replied that he would give life to 1,500.
And so began the existence of Death, caused by the hands of the proud Izanagi, and his abandoned wife Izanami.
As could be expected, Izanagi went on to purify himself after recovering from his descent to Yomi. As he undressed and removed the adornments of his body, each item that he dropped to the ground formed a deity. Even more gods came into being when he went to the water to wash himself. The most important ones were created once he washed his face:
Izanagi went on to divide the world between them with Amaterasu inheriting the heavens, Tsukuyomi taking control of the night and moon and the storm god Susanoo owning the seas. In some versions of the myth, Susanoo rules not only the seas but also all elements of a storm, including snow and hail, and, in rare cases, even sand.

Amaterasu, the powerful sun goddess of Japan, is the most well-known deity of Japanese mythology. Her feuding with Susanoo, her uncontrollable brother, however, is equally infamous and appears in several tales. One story tells about Susanoo's wicked behavior toward Izanagi, who, tired of Susanoo's repeated complaints, banishes him to Yomi. Susanoo grudgingly acquiesces, but has first to attend some unfinished business. He goes to Takamagahara ("heaven") to bid farewell to his sister, Amaterasu. Amaterasu knows that her unpredictable brother does not have good intentions and is prepared for battle. "For what purpose do you come here?" asks Amaterasu. "To say farewell," answers Susanoo.
But she does not believe him and requests a contest for proof of his good faith. A challenge is set as to who can bring forth more noble and divine children. Amaterasu creates three women from Susanoo's sword, while Susanoo makes five men from Amaterasu's ornament chain. Amaterasu claims the title to the five attributed to Susanoo.
Both gods declare themselves to be victorious. Amaterasu's insistence in her claim drives Susanoo to violent campaigns that reach their climax when he hurls a half-flayed pony (an animal sacred to Amaterasu) into Amaterasu's weaving hall and causes the death of one of her attendants. Amaterasu, angered by the display, hides in the cave called Iwayado. As the sun goddess disappears into the cave, darkness covers the world.
All of the gods and goddesses strive to coax Amaterasu out of the cave, but she ignores them all. Finally, the kami of merriment, Ame-no-Uzume, hatches a plan. She places a large bronze mirror on a tree, facing Amaterasu's cave. Then, Uzume clothes herself in flowers and leaves, overturns a washtub and begins to dance upon it, drumming the tub with her feet. Finally, Uzume sheds the leaves and flowers and dances naked. All of the male gods roar with laughter, and Amaterasu becomes curious. When she peeks outside, a ray of light called "dawn" escapes and Amaterasu is dazzled by the beautiful goddess that she sees, this being her own reflection in the mirror. The god, Ameno-Tajikarawo, pulls her from the cave, which is sealed with a shimenawa. Surrounded by merriment, Amaterasu's depression disappears, and she agrees to return with her light. Uzume is then known as the kami of dawn as well as of mirth.
Susanoo, exiled from heaven, comes to Izumo Province (now part of Shimane Prefecture). It is not long before he meets an old man and an old woman sobbing beside their daughter. The old couple explain that they originally had eight daughters who were devoured, one after the other, by the dragon, Yamata no Orochi ("eight-forked serpent", who is said to originate from Koshi--now Hokuriku region). The terrible dragon had eight heads and eight tails, stretched over eight hills, and is said to have eyes as red as good wine. Kushinada-hime ("rice paddy princess") was the last of the eight daughters.
Susanoo, who knew about the old couple's relation to Amaterasu, offers his assistance in return for their beautiful daughter's hand in marriage. The parents accept, and Susanoo transforms Kushinada into a comb and hides her safely in his hair. He also orders a large fence-like barrier to be built around the house. The fence has eight gates, with eight tables placed at each gate and eight casks placed on each table. Each cask is filled with eight-times-brewed rice wine.
Orochi arrives and finds his path blocked. After boasting about his prowess, he finds that he cannot get through the barrier. His keen sense of smell takes in the sake--which Orochi loves--and the eight heads are now faced with a problem. They want to drink the delicious sake, yet the fence blocks access to the sake. One head suggests that they simply smash the barrier, but that would knock over the sake. Another proposed that they combine their fiery breath and burn the fence to ash, but then the sake would evaporate. The heads begin to search for an opening. They find the hatches, and, eager for the sake, they wish to poke their heads through to drink it. Yet, the eighth head, which is the wisest, warns his brethren about the folly of such an act and volunteers to go through first to ensure that all is well. Susanoo waits for his chance. He allows the head to drink some sake in safety and to report to the others that there is no danger. All eight heads plunge through the hatches and greedily drink every drop of the sake.
As the heads finish, Susanoo launches his attack on Orochi. Drunken from drinking so much sake, the great serpent is no match for the spry Susanoo who decapitates and slays Orochi. A nearby river is said to have turned red with the blood of the defeated serpent. As Susanoo cuts the dragon into pieces, he finds an excellent sword from a tail of the dragon that his sword had been unable to cut. The sword is later presented to Amaterasu and named Ama no Murakumo no Tsurugi (?, "Sword of the Gathering Clouds of Heaven", which was later called Kusanagi, "Grass Cutter"). This sword was to feature prominently in many other tales.
Mostly known by his nickname ?kuninushi, ?namuji was a descendant of Susanoo, and represented the power structure localized in the Izumo area. ?kuninushi's people succeeded in unifying territory to some measure, but later relinquished control to the Yamato-based clans, as described in the Tenson k?rin chapter, below.
A tale of how the merciful ?kuninushi helped the beleaguered rabbit or hare is of enduring fame, and often told as a sort of a Mukashibanashi or "once upon a time tale". It is found in Kojiki but not recorded in the "Nihongi".
?kuninushi (at the time he was just ?namuji without the august nickname) had eighty brothers who were rival suitors courting Princess Yakami/Yagami (?) of Inaba to become her husband. They started out of their homeland of Izumo headed for the neighboring province, with Okuninushi brought along to follow and carry the luggage of his more eminent brothers. The brothers encountered a rabbit who had been flayed (by crocodile-fish, usually interpreted as sharks) and lay in agony upon a sea shore. In a wicked-hearted gesture, they advised the rabbit to bathe in the briny sea and blow himself dry in the wind. The rabbit found himself in worse agony. ?namuji, who came lagging behind, took pity on the creature and told the hare to wash in fresh water, then roll in the scattered fleece of cattail plants. The cured rabbit made a divined prediction that ?namuji would be the one to win Princess Yakami, "though thou bearest the bag,"
As the hare predicted, Princess Yakami pronounces her choice of ?namuji for husband before the eighty gods, and they all conspire and kill him twice over. His mother petitions Kamimusubi [ja], one of the creator deities, and resuscitates him each time, finally sending him off to seek Susanoo who has been banished to the Netherworld (Ne-no-kuni), and to obtain his wise counsel.
Here ?namuji meets face to face with Susanoo's daughter Suseri-hime and they immediately marry. The crafty Susanoo tests ?namuji several times, but, in the end, Susanoo approves of the young boy and foretells ?namuji's victory over his brothers.
Although the Yamato tradition attributes the creation of the Japanese islands to Izanagi and Izanami, the Izumo tradition claims that ?namuji, along with a dwarf god called Sukunabiko, contribute to, or at least finish, the creation of the Japanese islands.
In the Nihongi here begins the section entitled "Age of the Gods: Part II" (kamiyo ge-kan (?)).
The episode of the Tenson k?rin (? "Descent of the Heavenly Grandson") begins with description of how the heavenly gods (Ama-tsu-kami) who dwelled in the Heavenly Plains (Takama-ga-hara) peered down upon the earth below (known by the stilted name Ashihara no Nakatsukuni (? "Reedy Plains Middle World") which represents Japan specifically and not the whole world. To this land they dispatched various members of their own kind to subjugate it. Amaterasu had decreed her own grandson Ninigi to rule over the terrestrial world, but the terrestrial gods (kuni-tsu-kami) were not altogether willing to hand it over, and odd sorts of terrestrial gods were still lurking about making it too dangerous.
Some of the gods first appointed to quell the middle world were derelict in their mission, or joined leagues with the terrestrial gods. After several false starts, two gods were finally successful. They were Ame-no-ohabari [ja] (aka Itsu-no-ohabari; elsewhere this kami is said to be a sword) and Takemikazuchi. They embarked aboard the Ame-no-torifune [ja] or "Deity Heavenly-Bird-Boat" to their military campaign. These two sabre-rattling deities were able to frighten ?kuninushi's two sons into flight, causing ?kuninushi to abdicate and relinquish the territories to the Heavenly Grandson.
Amaterasu was now able to decree the Tenson k?rin (? "Descent of the Heavenly Grandson"), also referred to as amori, amakudari (, installing her grandson to rule over the terrestrial middle world. She endowed him the Three Sacred Treasures ( "descent from heaven")Imperial Regalia of Japan):
The mirror was to be worshipped as a representation of Amaterasu. A number of deities were made to make the descent at this time.
Ninigi met Konohanasakuya-hime (symbol of flowers), the daughter of Yamatsumi (master of mountains), and they fell in love. Ninigi asked Yamatsumi for his daughter's hand. The father was delighted and offered both of his daughters, Iwanaga (symbol of rocks) and Sakuya (symbol of flowers). However, Ninigi married only Sakuya and refused Iwanaga.
"Iwanaga is blessed with eternity and Sakuya with prosperity", Yamatsumi said in regret, "by refusing Iwanaga, your life will be brief from now on". Consequently, Ninigi and his descendants became mortal.
Sakuya conceived by a night and Ninigi doubted her. To prove legitimacy of her children, Sakuya swore by her luck and took a chance; she set fire to her room when she had given birth to her three babies. By this, Ninigi knew her chastity. The names of the children were Hoderi, Hosuseri and Howori.
Ninigi's elder son Hoderi or "Fire-Shine" had the gift of the bounty of the sea, and gained his livelihood by fishing (and bore the nickname Umisachihiko or "Luck of the Sea"). The younger son Hoori or "Fire-Fade" had the gift of the bounty of the mountains, and was a hunter (and nicknamed Yamasachihiko or "Luck of the Mountains").
One day, Luck of the Mountains asked his elder brother Luck of the Sea to exchange their tools and swap places for a day. He wanted to try his bid at fishing. But he did not catch a single fish, and worse, he lost his borrowed fishhook. To make amends, he shattered the very sword he was wearing to make a hundred, then a thousand hooks to replace what he lost, but the elder brother would accept nothing but the original fishhook.
Luck of the Mountains was sitting on a beach balefully weeping, there came to his aid Shiotsuchi-no-oji ["Tide-way god"] (one of the deities now enshrined at Shiogama Jinja). The tide god built him a small ship described as being manashikatsuma (?, "basket without interstices"), and sent him on a journey to the fish-scaled palace of the Watatsumi (Sea God, often conceived of as a dragon-god). There he had a fateful meeting with the Sea God's daughter Princess Toyotama, and married her. After three years, he remembered his brother and his fishhook, and was longing to return home.
Watatsumi gathered his piscean minions, and soon the fishhook was found in the throat of a bream (tai) and restored to Luck of the Mountains. The Sea God also imparted two magical balls: Shihomitsutama ( which could cause a flood, and Shihohirutama "Tide-flowing ball") ( which could cause water to recede and dry up. And he gave additional strategic advice to gain advantage from his contentious elder brother. So riding on a fathom-long crocodile-fish or shark (hitohiro-wani "Tide-ebbing ball") ()), they returned to dry land.
The pregnant Princess Toyotama built a cormorant feather-thatched maternity house and pleaded her husband for privacy, as she would be reverting to her true shape while delivering her child. But Howori (Luck of the Mountains) was overcome with curiosity, and peeped inside to discover her transformed into a crawling 8-fathom "croc-fish" (shark, dragon), and scuttered away in fright. Ashamed and disgusted by her husband's breach of trust, she abandoned the newborn and returned to sea. The infant prince was named Ugaya meaning "cormorant house".
Ugaya married his aunt, the sea princess Tamayori and had five children, including Iwarebiko, who was later to become Emperor Jimmu. In the Nihongi, the "Age of the Gods" (kamiyo ()) section ends here, and is followed by sections under the titles of the reigns of each Emperor.
The first legendary Emperor of Japan, best known by his posthumous name of Emperor Jimmu was referred to in the records by the title of Iwarebiko (/? Kamu-yamato Iware-biko no-mikoto). He is the son of Ugaya, descendant of Ninigi, and the sea princess Tamayori. His given name was Hiko-hohodemi.
After Jimmu's death, an elder prince named Tagishishimi [ja] (who was not first in line as successor) moved to consolidate power under him while everyone else was in mourning, and plotted to slay his two younger half-brothers. The plot was suppressed, and the younger prince who had the courage to pluck the bow and shoot Tagishishimi fatally was cede the crown to become the next emperor, Suizei.
Of the eight emperors who succeeded Jimmu, there is very little record of their deeds, so they are described collectively under Book III of Nihon Shoki. Regarding Emperor Suizei, the foregoing description of how he suppressed his elder brother's insurrection. And for the other legendary rulers, not much more than their genealogy is given.
Nihon shoki (Suinin 28; 2 B.C.) states that when his uncle died, all his closer retainers were buried around in perimeter around the kofun tumulus, but their wailings could be heard for days. (Note: the word junshi () also includes such deaths compelled upon retainers. cf. similar forced sacrificial burials were evidenced from Shang Dynasty grave sites in China.) This emperor allegedly decided this practice was cruel and must cease; and, four years later, he adopted the idea forwarded by Nomi no Sukune to bury clay figurines called haniwa instead of live men.
The Kojiki reports that during the reign of the 11th emperor Suinin, a man named Tajimamori was sent to Tokoyo-no-kuni (? "Eternal Land") in a quest for the tokijiku-no-kaku-no-konomi (, ? "fruit of the everlasting fragrant tree"). He was able to gather eight vine-like trees and eight spear-like trees. But by the time he returned, the Emperor was dead. The Kojiki identifies the fruit as the tachibana, a type of small, sour citrus.
Tajimamori has later been hailed as the Kami of wagashi (Japanese confection and sweets), revered at Nakashima Shrine [ja] in Toyooka, Hy?go, though this is little known trivia to the average Japanese.
The Nihon shoki dates Tajimamori's travel to Suinin 90 (purportedly 61 A.D.), and makes him out to be the great-grandson of Amenohiboko, a Korean prince who came to Japan just two years earlier. However this is anachronistic according to Kojiki, which places Amenohiboko in a much later era.
It is probably more typical to find lists of items and weapons that appear in the Japanese mythology. However, here is a tentative list of creatures:
