When people think of Japan, they often picture cherry blossoms, sushi, anime, or ancient temples. But behind almost all of it sits a much older story — one that has been passed down for more than 1,300 years.
That story is called the Kojiki.
Here’s something surprising: if you’ve ever played Ōkami, watched Naruto, or seen the sun goddess Amaterasu appear in a video game, you’ve already met the Kojiki without knowing it. These gods didn’t come from a game studio. They came from this book.
What Is the Kojiki?
The Kojiki — “Records of Ancient Matters” — was completed in 712 AD and is one of Japan’s oldest surviving books. It was put together by a court official named Ō no Yasumaro at the request of Empress Genmei, drawing on older oral traditions that had been memorized and passed down for generations.
Part history, part mythology, and part cultural memory, the Kojiki tells how the Japanese people understood where they came from. It opens with the creation of heaven and earth, then moves through the age of the gods and into the early legendary emperors.
Among the most important gods it introduces are:
- Amaterasu, the Sun Goddess
- Susanoo, the God of Storms and Seas
- Tsukuyomi, the Moon God
The Story of How Japan Was Born
One of the most famous tales is about the divine couple Izanagi and Izanami.
Standing on a floating bridge in the sky, they dipped a jeweled spear into the ocean below and stirred. When they lifted it, drops fell from the tip — and those drops became the islands of Japan.
We read this today as myth, not history. But it reveals something about how ancient Japanese people saw their home: not just a place to live, but a land woven together with nature and the divine.
The Goddess Who Hid the Sun
Another well-known episode involves Amaterasu, the Sun Goddess, and her wild brother Susanoo.
After Susanoo caused chaos in the heavens, Amaterasu grew so upset that she shut herself inside a cave and sealed the entrance with a boulder. Without her light, the entire world fell into darkness.
The other gods tried everything to coax her out. Finally, they held a noisy, joyful celebration just outside the cave — with music, dancing, and laughter. Curious about the commotion, Amaterasu peeked out, caught sight of her own glittering reflection in a mirror the gods had hung nearby, and was drawn forward just far enough for the others to pull her out. Light returned to the world.
It’s a simple story, but it captures something the Kojiki returns to again and again: light, renewal, and the power of community to bring someone back.
The Values Hidden Inside the Stories
The Kojiki is more than gods and adventures. Running underneath it are values that still echo through Japanese culture today:
- Respect for nature
- Harmony within the community
- Gratitude toward ancestors
- Pride and care in one’s work
You don’t have to read the Kojiki to feel these. They show up in festivals, shrines, and the rhythm of the seasons.
The Connection to Japan’s Imperial Family
The Kojiki also traces the origins of Japan’s Imperial Family back to Amaterasu, the Sun Goddess. For centuries, these stories helped preserve a sense of continuity and identity.
Today, Japan’s Imperial Family is widely described as the world’s oldest continuing hereditary monarchy — a living thread connecting the present to the age the Kojiki describes.
Why the Kojiki Still Matters
In a fast-moving modern world, it’s easy to forget the stories that shaped earlier generations. Yet the Kojiki keeps speaking to people because it asks questions every culture asks:
- Where do we come from?
- What do we owe the people who came before us?
- How should we live alongside nature?
These questions were written down more than a thousand years ago — and they remain just as alive today.
Whether read as history, mythology, or cultural heritage, the Kojiki offers a window into how generations of Japanese people understood their origins, and into the spirit that still runs quietly through the culture today.
