Why Are Uchiha Jutsus Named After Japanese Gods?

The Uchiha's Eye Powers Came From Eyes in the Original Myth

When Itachi activates Tsukuyomi from his right eye, that is not a coincidence. When Amaterasu erupts from the left, that is not decoration. Masashi Kishimoto built the entire Uchiha jutsu system on one specific scene from Japan's oldest religious text - a scene where the most powerful gods in the Shinto pantheon are literally born from someone's eyes.

Once you know that scene, every single Uchiha Mangekyou technique stops being a cool name and becomes a piece of a 1,300-year-old story.

Here's the thing: the Uchiha clan are defined by their eyes. Their power comes from their eyes. Their suffering comes from their eyes. And in the original mythology, the gods they named their jutsu after - Amaterasu, Tsukuyomi, Susanoo - were born from the same act of washing eyes. Kishimoto didn't just borrow the names. He mapped the anatomy.

Key Takeaways

• The Kojiki (古事記, Kojiki), Japan's oldest chronicle (712 CE), is the source of every Uchiha Mangekyou jutsu name
• In the myth, Amaterasu was born from Izanagi's left eye, Tsukuyomi from his right - Itachi's jutsu mirror this exactly
• Susanoo is the real storm god who slew the eight-headed serpent Yamata no Orochi and found the legendary sword Kusanagi inside its tail
• Amaterasu and Tsukuyomi became enemies after Tsukuyomi killed a food goddess - that is why the sun and moon never share the sky
• Izanagi and Izanami are the creator couple whose tragic separation sets up the underworld mythology behind the Izanagi/Izanami jutsu
• Kagutsuchi is the fire god whose birth killed his mother - Sasuke literally controls the fire god, which is what Kagutsuchi the technique does to Amaterasu's flames
• Key vocabulary: 天照 Amaterasu (heaven-illuminating), 月読 Tsukuyomi (moon-reading), 古事記 Kojiki (record of ancient matters)

The Book Behind All of This

The Kojiki (古事記) - "Record of Ancient Matters" - is Japan's oldest chronicle. Compiled in 712 CE under Empress Genmei's orders, it records the Shinto creation myth, the age of the gods, and the genealogy of the imperial family. It is the foundation document of Shinto theology.

The name breaks down cleanly: 古 (ko, ancient), 事 (ji, matters/things), 記 (ki, record/chronicle). The oldest record of the oldest things.

Every Uchiha Mangekyou technique name - Amaterasu, Tsukuyomi, Susanoo, Izanagi, Izanami, Kagutsuchi - comes from this one text. They are not separate myths. They are all characters in the same story, and the connections between them are exactly what Kishimoto encoded into the jutsu system.

The Purification Scene - Where Three Gods Were Born From Eyes

Here is the scene that ties everything together.

Izanagi (イザナギ) and Izanami (イザナミ) were the creator couple. Together they created the islands of Japan, stirring the primordial ocean with the Jeweled Spear of Heaven. But when Izanami gave birth to Kagutsuchi (カグツチ), the god of fire, his body burned her from the inside as she delivered him. Izanami died of her wounds and descended to Yomi (黄泉, Yomi) - the underworld.

Izanagi, devastated, descended into Yomi to bring her back. He called to her in the darkness. She told him not to look at her, that she was negotiating with the gods of the underworld.

He couldn't wait. He broke off a tooth from his comb and lit it as a torch.

What he saw was not his wife. It was a rotting corpse crawling with maggots and thunder demons.

He fled in horror. Izanami, humiliated and furious, sent the thunder demons and hags of Yomi after him. He barely escaped, blocking the entrance to the underworld with a giant boulder. Standing at the boulder, Izanami screamed that she would kill a thousand of his people every day. Izanagi replied that he would then create fifteen hundred births every day. Their relationship was over.

Izanagi emerged from the underworld covered in death-filth. He went to the river Ahaji to purify himself. He stripped and waded in.

When he washed his left eye, the sun goddess Amaterasu (天照大御神, Amaterasu Omikami) was born.

When he washed his right eye, the moon god Tsukuyomi (月読命, Tsukuyomi-no-Mikoto) was born.

When he washed his nose, the storm god Susanoo (建速須佐之男命, Takehaya Susanoo-no-Mikoto) was born.

These three became the Mihashira-no-Uzu-no-Miko (三貴子) - the Three Noble Children, the most exalted of all gods, assigned to rule the heavens, the moon, and the seas respectively.

Now look at Itachi's eyes again. Left eye: Amaterasu. Right eye: Tsukuyomi. The map is exact.

Amaterasu - The Sun That Refuses to Die

Amaterasu (天照) - "heaven illuminating" - is the ruler of Takamagahara, the high heavens. She is the most powerful deity in the Shinto pantheon and the divine ancestor of the Japanese imperial family. Her Sacred Mirror (八咫鏡, Yata no Kagami) is one of the Three Imperial Treasures of Japan.

Her most famous story involves the cave.

After Susanoo was banished from heaven (more on that shortly), he returned to say goodbye to his sister Amaterasu before departing. But his arrival was so violent - mountains shaking, seas boiling - that Amaterasu suspected an invasion and armed herself. The confrontation between them was tense but peaceful, and Susanoo departed.

Then he went on a rampage across the heavenly fields. He destroyed the rice paddies Amaterasu had planted, filled in the irrigation ditches, and defiled her sacred weaving hall. One of her weaving maidens died in the chaos. Amaterasu, overwhelmed, retreated into the cave of Ama-no-Iwato (天岩戸, Amano-Iwato, "Heaven's Rock Cave") and sealed the entrance.

The world went dark. Evil spirits emerged. The other gods panicked.

Eight million gods gathered outside the cave and devised a plan. They had the goddess Ame-no-Uzume (天宇受売命) perform an increasingly wild and comical dance outside the cave, causing the assembled gods to burst into uproarious laughter. The noise of eight million gods laughing in the darkness confused and intrigued Amaterasu enough that she cracked the boulder open to peek out. A god named Ame-no-Tajikarao seized her hand and pulled her out. Another god quickly placed a sacred rope (shimenawa) behind her so she couldn't return.

Light came back to the world.

In Naruto, Amaterasu is the black flames that never go out, that burn through anything, that cannot be extinguished by conventional means. They are the flames of the sun - the sun that, in the myth, literally extinguished itself and plunged the world into darkness when it withdrew. The technique captures exactly that concept: a fire so absolute that its absence is catastrophic.

Tsukuyomi - The Reason Sun and Moon Never Share the Sky

Tsukuyomi (月読) - "moon-reading" - was assigned by Izanagi to rule the night and the realm of the moon. For a while, he and Amaterasu ruled together in the heavens.

Then he killed someone.

A food goddess named Uke Mochi (宇気母智神) was preparing a feast for the gods. When Tsukuyomi arrived as Amaterasu's envoy, Uke Mochi prepared food in a way that Tsukuyomi found repulsive - producing it from her own body. He was so disgusted that he drew his sword and killed her on the spot.

When Amaterasu learned what had happened, she was furious. She declared that she would never look at Tsukuyomi again, calling him a wicked and vile god.

And she hasn't looked at him since.

The sun and moon are in different parts of the sky, moving in different spheres, never occupying the same space. That separation - the estrangement of two siblings who once shared heaven - is the mythological explanation for why day and night alternate instead of coexisting. Amaterasu refuses to share the sky with the god who killed in her name without cause.

In Naruto, Tsukuyomi is Itachi's most feared technique: a genjutsu (illusion) that traps victims in a subjective reality where time moves differently, allowing him to subject them to years of torture in the span of a second. It is activated from the right eye - the moon-god eye. The connection is not just the name: Tsukuyomi controls the experience of time in the myth too, governing the slow wheel of night, the calendar, and the rhythm of seasons. A god who shapes experienced time becomes a jutsu that collapses and stretches time inside a victim's mind.

Susanoo - The Storm God Who Found the Most Famous Sword in Japan

Susanoo (スサノオ) is the most dramatic of the three siblings. He was assigned to rule the seas and the storms, but he spent most of his time weeping and throwing tantrums because he missed his dead mother Izanami. His grief caused chaos - mountains shook, seas went wild, evil spirits multiplied. Izanagi finally lost patience and banished him from heaven.

After the incident with Amaterasu's rice paddies, Susanoo descended to the province of Izumo on earth, landing near the headwaters of a river. He noticed chopsticks floating downstream - a sign that people lived upstream. He found an elderly couple weeping with their young daughter Kushinadahime (奇稲田姫, Kushinada-hime). They explained that a monster called Yamata no Orochi (八岐大蛇, "eight-branching great serpent") had already eaten seven of their eight daughters. It was coming for the last one.

Yamata no Orochi had eight heads and eight tails, eyes red like cherries, a body that covered eight valleys and eight hills, belly permanently bleeding and rotting. The heads drank from eight separate branches of the river simultaneously.

Susanoo had a plan. He instructed the family to brew eight separate vats of sake (酒, sake, rice wine) - one for each head. He transformed Kushinadahime into a comb and put her in his hair for safekeeping. When Yamata no Orochi arrived, it drank all eight vats and collapsed drunk. Susanoo drew his ten-span sword and cut the serpent to pieces.

In one of the tails, his sword hit something solid. He reached inside and pulled out a magnificent blade: Kusanagi-no-Tsurugi (草薙の剣, Kusanagi-no-Tsurugi, "Grass-Cutting Sword"). Recognizing it as a divine object, he sent it to Amaterasu as a gift of reconciliation. That sword became one of the Three Imperial Treasures of Japan, the same set that includes Amaterasu's Sacred Mirror - objects so sacred they are never shown publicly.

In Naruto, Susanoo is the massive chakra avatar that manifests around its user - an armored giant that serves as both weapon and shield. The technique often culminates in a final sword form, mirroring Susanoo the god's decisive sword strike that produced the legendary blade. What is less obvious is that Susanoo in the myth is a god who is fundamentally exiled and alone - banished from heaven, working on earth, a storm that destroys everything around it. The Susanoo-users in Naruto carry the same energy: Itachi protecting what he loves while destroying everything around himself, Sasuke exiling himself from Konoha, Madara having burned every bridge there was.

Izanagi, Izanami, and the Birth of Death

Izanagi (イザナギ) and Izanami (イザナミ) are not minor characters in Shinto mythology. They are the primary creator deities who shaped existence itself. Izanagi means roughly "the male who invites" and Izanami means "the female who invites."

Together they stood on the Floating Bridge of Heaven and stirred the primordial ocean with the Jeweled Spear. When they lifted the spear, drops fell and formed the first island of Japan.

Their separation - her death, his descent into Yomi, his horror at her decay, his flight, their final divorce - is not just a tragedy. It establishes the central structural feature of the Japanese cosmos: a living world above and a dead world below, separated by a boulder, with Izanagi and Izanami standing permanently on opposite sides.

In Naruto:

• Izanagi rewrites the user's reality to change a fatal outcome into an illusion - turning death into a dream. Exactly what Izanagi tried to do by descending into Yomi: undo a death that should have been permanent.
• Izanami traps the target in an endless loop of the same experience, forcing them to repeat a critical moment forever. Exactly the fate Izanami condemned the dead to: existence in Yomi, unable to return, unable to change. She is the goddess of the unchangeable underworld. The technique makes the target's world as fixed as death.

The cost of using Izanagi in Naruto - permanent blindness in that eye - mirrors the Kojiki logic: Izanagi escaped death but lost his wife, lost his purity, lost the divine completeness he had before entering the underworld. Using the power of the creator god costs something that cannot be recovered.

Kagutsuchi - The Fire God Who Killed His Own Mother

Kagutsuchi (カグツチ, also Hi-no-Kagutsuchi, "fire-burning-elder") is the fire deity whose very existence caused the first death in Japanese mythology.

When Izanami gave birth to him, his burning body scorched her from the inside. She died in agony. Izanagi's grief was so complete that he wept, and from his tears four more deities were born. Then, in his rage at the child who had killed his wife, Izanagi drew his sword and killed Kagutsuchi - cutting him into eight pieces, from which eight more fire and mountain deities were created.

Kagutsuchi is a force of uncontrollable fire that destroyed the thing that created him. He is the fire that burns its own source.

In Naruto, the technique Kagutsuchi (カグツチ) allows Sasuke to shape and control the black flames of Amaterasu. He who was born from the fire controls the fire. The Uchiha clan's power - their Amaterasu - becomes a tool rather than a force of nature, controllable by a separate technique named after fire's own uncontrollable god. The mythology even works here: Kagutsuchi was killed and divided by Izanagi, his power distributed and controlled. The jutsu takes that power and redistributes it under the user's will.

Vocabulary Callout

These terms come from the Kojiki, appear in Naruto, and show up in modern Japanese culture regularly:

The distinction between 眼 (gan) and 目 (me) is worth knowing for lyrics and poetry. 眼 is the more literary, formal character - you'll see it in technique names and poetic writing. 目 is everyday. Sharingan (写輪眼, Sharingan) uses 眼 (gan) - it's a written, literary eye, not the casual body-part word. That choice signals something mystical before you've even read a translation.

Why This Matters for Your Japanese

Masashi Kishimoto didn't name jutsu at random. He built a coherent theological system where the Uchiha clan is, effectively, a family of humans trying to wield the powers of the gods who shaped existence - and paying the same price those gods paid. Itachi's blindness. Sasuke's isolation. Obito's identity collapse. The mythology says: these powers cost everything, because they come from the moment a god lost everything.

When you encounter 天照 (Amaterasu) in a Japanese text, you're not just seeing a Naruto technique name. You're seeing the character for heaven and the character for illuminate - a compound whose meaning is embedded in the image itself. Japanese writing works that way constantly. Kanji are pictures stacked inside meanings, and anime borrowed those pictures from a tradition that goes back over a thousand years.

KitsuBeat lessons are built around anime songs where this layer of meaning shows up in every other line - not just Naruto, but across the genre, wherever Japanese writers reach for the vocabulary of gods and storms and eyes and fire. Explore the song library on KitsuBeat and look for the vocabulary callouts in each lesson. The kanji you learn from one song will land differently in the next one once you know where it came from.

FAQ

Is Amaterasu from Naruto based on a real Japanese goddess?

Yes. Amaterasu (天照) is the Shinto goddess of the sun and ruler of the heavens, one of the most important deities in the Kojiki (712 CE). In the original myth, she was born when the god Izanagi washed his left eye after escaping the underworld. In Naruto, Amaterasu is Itachi and Sasuke's black-flame technique activated from the left eye - a direct mirror of the myth.

Why does Itachi use Tsukuyomi from his right eye and Amaterasu from his left?

Because that is exactly how the original myth works. In the Kojiki, when Izanagi washed his left eye, the sun goddess Amaterasu was born. When he washed his right eye, the moon god Tsukuyomi was born. Masashi Kishimoto mapped the anatomy directly: Itachi's left eye casts Amaterasu (sun fire) and his right eye casts Tsukuyomi (moon genjutsu), mirroring the left-eye/right-eye births in the Kojiki.

What is the Kojiki and where does it come from?

The Kojiki (古事記, Record of Ancient Matters) is Japan's oldest chronicle, compiled in 712 CE under Emperor Genmei. It records the creation myth, the age of the gods, and the genealogy of the imperial family. It is the primary source for Shinto theology and the origin of every Uchiha Mangekyou technique name.

Did Susanoo exist before Naruto?

Yes. Susanoo (スサノオ) is the Shinto god of storms, born when Izanagi washed his nose during the same purification ritual that produced Amaterasu and Tsukuyomi. In the Kojiki, Susanoo is banished from heaven after causing chaos, descends to earth, and slays the eight-headed serpent Yamata no Orochi - discovering the legendary sword Kusanagi inside its tail. In Naruto, Susanoo is the massive armored chakra avatar that surrounds its user.

Is Izanagi in Naruto based on the real creation god?

Yes. Izanagi (イザナギ) is the male creator deity of Japanese mythology who helped create the islands of Japan with his wife Izanami. After Izanami died and became the goddess of the underworld, Izanagi famously descended into Yomi to retrieve her - but fled when he saw her rotted body, escaping by blocking the entrance with a boulder. In Naruto, the Izanagi technique rewrites reality to change a fatal outcome to a dream - mirroring how the mythological Izanagi tried to undo his wife's death.

What is Kagutsuchi in Japanese mythology?

Kagutsuchi (カグツチ) is the Shinto god of fire. His birth was so violent that the heat of his body burned and killed his mother, the goddess Izanami, as she gave birth to him. This is the event that begins Izanami's descent into the underworld. In grief and rage, Izanagi killed Kagutsuchi with his sword. In Naruto, Kagutsuchi is Sasuke's technique for shaping and controlling the black flames of Amaterasu - the user of fire controlling the fire god.

Why are all Uchiha Mangekyou jutsu named after Shinto gods?

Masashi Kishimoto designed the Uchiha clan as a family with an almost religious connection to power and sacrifice, drawing from Shinto mythology as the thematic backbone. The Mangekyou Sharingan jutsu names form a complete set: Amaterasu (left eye, sun), Tsukuyomi (right eye, moon), Susanoo (the storm avatar), Izanagi (rewriting reality), Izanami (trapping in loops), Kagutsuchi (fire control). Every name comes from the same creation narrative in the Kojiki.
