Izanagi and Izanami (伊弉諾尊・伊弉冉尊): Creation story and the origins of Japan

---

Who were Izanagi and Izanami in Japanese mythology?

Izanagi and Izanami are described in the Kojiki and the Nihon Shoki, two of Japan’s oldest mythological texts, as a divine couple entrusted with the task of creating the land. Their names themselves carry meaning: Izanagi can be translated as “He Who Invites,” while Izanami means “She Who Invites.” Together, they represent a balance of masculine and feminine forces, a harmony through which creation becomes possible. Unlike many distant creator gods in other cultures, they are depicted in humanlike form, complete with emotions, struggles, and even tragic losses. This makes them relatable figures while still embodying cosmic power.

How did Izanagi and Izanami create the islands of Japan?

According to the myth, the heavenly deities commanded Izanagi and Izanami to bring order to a world that was still formless. Standing upon the Floating Bridge of Heaven, they stirred the chaotic sea with a jeweled spear known as the Ame-no-nuboko. When they lifted the spear back up, drops of brine fell from its tip, solidifying into the first island: Onogoro-shima.

Descending to this island, the divine pair built a pillar and circled it in opposite directions. Upon meeting, they performed the first marriage ritual. From this union, the islands of Japan began to emerge, each one carrying divine essence. Thus, the very geography of Japan is explained as the outcome of sacred love and ritual, tying the land itself to the presence of gods.

Why did tragedy strike during their union?

Though their first attempts at creation were flawed, with deformed offspring born from "their initial union," the gods instructed them to repeat the ritual properly. This time, Izanagi spoke first rather than Izanami, and their union produced the great islands of Japan along with numerous kami, or deities, that governed aspects of nature and life.

Yet tragedy followed. Izanami gave birth to the fire god, Kagutsuchi, whose flames fatally burned her. This marked the first death in mythological history, introducing the inevitability of mortality into the world. The grief of Izanagi over losing his beloved became the starting point for the myth’s darker chapters.

What role did the underworld (Yomi) play in their story?

Izanagi, unwilling to accept Izanami’s death, journeyed into Yomi, the land of the dead, to retrieve her. However, when he found her, she had already eaten the food of the underworld, binding her to that realm. In the shadows, she begged him not to look upon her, but Izanagi, longing for her return, disobeyed.

The sight that met his eyes was horrific: Izanami’s once-beautiful form had decayed into a corpse crawling with maggots and guarded by thunder deities. Horrified, Izanagi fled while Izanami, enraged at his betrayal, pursued him with the fury of the dead. He narrowly escaped by sealing the entrance to Yomi with a massive boulder. From that moment, the boundary between life and death was set, and Izanami became a permanent figure of the underworld.

How did Izanagi cleanse himself after Yomi?

After escaping the filth of Yomi, Izanagi felt polluted and impure. He bathed in a river to cleanse himself, a ritual act known as misogi. From this act of purification, new gods were born from his discarded garments and the very waters that washed over him. Most famously, three powerful deities emerged: Amaterasu, the sun goddess; Tsukuyomi, the moon god; and Susanoo, the storm god.

This moment is crucial, as it not only explains the origins of major Shinto deities but also establishes purification as a central practice in Japanese religion. To this day, rituals of cleansing, whether washing hands at a shrine or larger ceremonies, trace their symbolism back to Izanagi’s act of washing away the darkness of death.

What does this creation story teach about life and death?

The myth of Izanagi and Izanami intertwines creation with destruction, life with death, and love with separation. It portrays existence as a balance of forces that cannot be separated: from birth comes death, and from death comes renewal. The underworld episode explains why humans cannot escape mortality, while Izanagi’s purification highlights the possibility of spiritual renewal.

The story also elevates the idea that sacred order requires ritual, boundaries, and respect for divine law. Just as Izanagi failed when he ignored Izanami’s plea, humanity must understand that transgressing spiritual boundaries comes with consequences.

Why is this myth central to the identity of Japan?

Unlike many myths that place creation in distant lands, the story of Izanagi and Izanami ties the origins of the Japanese islands directly to divine action. This creates a sacred geography, where the land itself is not just territory but a living manifestation of divine will. The imperial family of Japan traced its lineage back to Amaterasu, born from Izanagi, thereby rooting political authority in the same divine narrative.

"For centuries," this myth was not just a story but a foundation for national identity, connecting the people of Japan to their land and gods in an unbroken chain.

How does their story compare to other world creation myths?

While many cultures describe gods forming the world out of chaos, the Japanese version is unique in its emphasis on partnership, ritual, and the physical shaping of the land. Unlike in Greek mythology, where chaos is subdued by solitary gods, or Mesopotamian myths that describe violent battles of creation, Izanagi and Izanami create through union and ceremony.

Their myth also resembles themes in other cultures where journeys to the underworld signify transformation, such as the Greek myth of Orpheus and Eurydice. Yet, the Japanese version underscores the inevitability of death and the need for purification afterward, making it deeply tied to Shinto practice rather than just symbolic narrative.

What lasting influence does the Izanagi and Izanami myth have on Japanese culture?

Shrines dedicated to these deities still exist, and their story remains a cornerstone of Shinto belief. Rituals of purification, the sacredness of marriage ceremonies, and the understanding of life and death cycles are all influenced by their myth. Even modern Japanese culture, from literature and theater to contemporary anime, draws upon the imagery of Izanagi’s descent into Yomi and Izanami’s transformation.

Their narrative is not confined to ancient texts but continues to shape cultural identity, connecting people to an ancient understanding of existence.
