Exploring Izumo Fudoki: The Ancient Chronicle of Japan’s Mythical Heartland
When travelers think of ancient Japan, images of Kyoto’s temples or Nara’s deer often come to mind. However, to truly understand the spiritual bedrock of the nation, one must look further west to the Shimane Prefecture, historically known as Izumo. Central to this region’s identity is the Izumo Fudoki (出雲国風土記), a rare and fascinating text that offers a window into the Japan of the 8th century. Unlike the imperial histories written by the central court, this ancient gazetteer provides a raw, local perspective on the myths, geography, and culture of the “Land of the Gods.”
Origins: A Local Report to the Empress
The story of the Izumo Fudoki begins in 713 AD, when Empress Gemmei issued an imperial decree ordering the compilation of Fudoki—reports describing the geography, products, fertility of the land, and oral traditions of Japan’s various provinces. While over 60 provinces likely submitted these reports, time has been unkind to most of them. Only fragments remain of the reports from Hitachi, Harima, Bungo, and Hizen.
The Izumo Fudoki, completed in 733 AD, stands alone as the only nearly complete manuscript to survive to the modern day. It is a treasure trove of anthropological data, listing everything from the types of fish caught in the rivers to the specific names of mountains and shrines. More importantly, it diverges significantly from the official court histories, the Kojiki and the Nihon Shoki. While the court texts focused on legitimizing the Imperial family in Yamato (modern-day Nara), the Izumo Fudoki proudly centers on local deities and a worldview where Izumo is a powerful, independent realm.
Legend: The Myth of Kunibiki
The most compelling narrative found within the Izumo Fudoki is the legend of Kunibiki, or “Land-Pulling.” This myth explains the unique geography of the Shimane peninsula and stands in stark contrast to the creation myths of the rest of Japan.
According to the text, the giant god Yatsukamizu-omitsunu looked upon the land of Izumo and decided it was too small—a “strip of young cloth” not yet fully formed. Possessing immense strength, he looked across the sea to finding excess land in Silla (Korea) and other regions. He cast a rope, hooked these lands, and with a mighty heave, pulled them across the Sea of Japan, stitching them onto Izumo to enlarge it.
The myth describes the geography vividly: the ropes used to pull the land became the long, sandy beaches of Yomi-ga-hama and Sono-no-nagahama. The massive stakes driven into the earth to anchor the new lands became Mount Daisen and Mount Sanbe. This legend not only reflects the geological reality of the region’s coastline but also hints at the deep historical trade and cultural connections between ancient Izumo and the Korean Peninsula.
Modern Culture: The Land of the Gods
The legacy of the Izumo Fudoki is not confined to dusty scrolls; it is alive in the cultural heartbeat of modern Shimane. Izumo is still referred to as the “Land of the Gods” (Kami-no-kuni). This ancient distinction is most visible during the tenth month of the lunar calendar.
While the rest of Japan calls this month Kannazuki (The Month without Gods), in Izumo, it is called Kamiarizuki (The Month of the Gods). Tradition holds that all eight million deities of the Shinto pantheon leave their local shrines to gather at Izumo Taisha (Izumo Grand Shrine) for a divine conference on human destiny and relationships (en-musubi). The Izumo Fudoki provides the foundational context for this deep-seated spiritual authority, emphasizing a religious tradition that parallels, rather than submits to, the Ise traditions of the Imperial court.
Traveler’s Tips: Walking the Pages of History
For cultural travelers, the Izumo Fudoki serves as the ultimate guidebook. Here is how you can experience the legends today:
1. Visit the Shimane Museum of Ancient Izumo
Before exploring the sites, stop by this world-class museum located next to the Grand Shrine. It houses diverse artifacts and exhibits explaining the Fudoki, offering excellent English descriptions of the Kunibiki myth and ancient bronze weaponry found in the region.
2. Stand on Inasa Beach
Located a short walk from Izumo Taisha, this is the sacred beach where the gods are welcomed during the Kamiarizuki festival. It is also geographically significant in the land-pulling myths. The iconic Benzaiten rock formation against the sunset is a must-see.
3. Hike Mount Sanbe
For the adventurous, hiking Mount Sanbe offers a connection to the “stake” used by the god Yatsukamizu-omitsunu. It is a dormant volcano with stunning panoramic views, allowing you to gaze out over the land that myth says was pulled across the ocean.
4. Pilgrimage to Izumo Taisha
No trip is complete without bowing at Izumo Taisha. Unlike other shrines where you clap twice, here visitors clap four times—two for themselves and two for their partners (current or future), symbolizing the shrine’s power over relationships and destiny.
