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.^[9]

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).^[10] The two descended to the island and, setting up their dwelling, erected a 'heavenly pillar' (ame 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.^[11]

The 'Eight Great Islands' (大八洲 Ōyashima) of Japan begotten by Izanami and Izanagi

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)^[12]

The two then proceeded to beget the various deities who are to inhabit these lands.^[13] Izanami, however, was badly injured and eventually died after giving birth to the fire god Kagutsuchi.^[14] 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.^[15][16]

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. 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 and bade it to grow in the land of the living to help people in need. When Izanami herself came in pursuit of him, Izanagi sealed the entrance to Yomi using a huge boulder. Izanami then pronounces a curse, vowing to kill a thousand people each day, to which Izanagi replies that he will then beget a thousand and five hundred people everyday to thwart her.^[17][18][19]

Purification (Misogi)

Izanagi purifying himself (misogi) by immersing in a river (Natori Shunsen)

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.^[20][21]

Izanagi and Susanoo

Izanagi divides the world among his three children: Amaterasu was allotted Takamagahara (高天原, the "Plain of High Heaven"), Tsukuyomi the night, and Susanoo the seas.^[22] Susanoo did not perform his appointed task and instead kept crying and howling "until his beard eight hands long extended down over his chest," causing the mountains to wither and the rivers to dry up. After saying to his father that he wished to go to his mother's land, Ne-no-Katasu-Kuni (根堅州国, the 'Land of Roots'), a furious Izanagi then expelled Susanoo "with a divine expulsion," after which he disappears from the narrative.^[23][24]
