Within the Nihon Shoki and the broader Shinto cosmology, Izanagi and Izanami appear as a primordial divine couple, often rendered as “He-Who-Invites” and “She-Who-Invites.” They are presented as a male and female pair, joined as husband and wife, who stand at a crucial threshold in the unfolding of the cosmos. Commanded by the earlier heavenly deities, they are entrusted with bringing form and order to the still-chaotic earth. Their identity as a complementary pair already hints at a vision of reality in which creation arises through harmonious interaction of masculine and feminine principles.

Their most renowned role is as creators of the Japanese islands, a process known as kuniumi, the “birth of the land.” Standing upon the Floating Bridge of Heaven, they stir the primordial sea with a jeweled spear, and the droplets that fall from its tip solidify into the first island. Descending there, they establish a pillar and a palace, and through a ritual union they beget the “Great Eight Islands” of Japan and additional islands. This mythic geography does more than explain physical landforms; it sacralizes the very ground of the archipelago as the living body of a divine act.

Beyond shaping the land, Izanagi and Izanami are also portrayed as the progenitors of a vast array of kami, a process called kamiumi, the “birth of the gods.” From their union emerge deities associated with wind, sea, mountains, rivers, and many other aspects of the natural and social order. In this way, the couple functions as a fountainhead for the Shinto pantheon, suggesting that every facet of the world, from landscape to human culture, is permeated by divine presence. The cosmos is thus imagined as a great family whose members trace their lineage back to this original pair.

Yet their story also turns toward loss, death, and separation. Izanami dies while giving birth to the fire deity Kagutsuchi, and her passing introduces the reality of death into the mythic narrative. Grief-stricken, Izanagi descends to Yomi, the land of the dead, in an attempt to retrieve her, only to encounter her decayed form. His horrified flight and the sealing of Yomi with a great boulder establish a permanent boundary between the realms of the living and the dead, and their ensuing exchange about the daily number of deaths and births offers a mythic explanation for mortality and continual renewal.

After returning from Yomi, Izanagi undergoes ritual purification, an act that becomes archetypal for Shinto notions of cleansing and renewal. As he removes his garments and washes his body, new deities are born, most notably Amaterasu, the sun goddess, Tsukuyomi, the moon deity, and Susanoo, associated with storms and the sea. These beings stand at the center of later mythic cycles and imperial ideology, yet they also emerge from a moment of purification after contact with death and impurity. In this way, the narrative of Izanagi and Izanami weaves together creation and dissolution, defilement and purification, suggesting that the sacred order of the world is continually reborn out of the very tensions it contains.
