Unveiling the Iyo Fudoki: The Mythical Roots of Ehime
Japan is a land where history breathes through the landscape, where every mountain, river, and hot spring holds a story etched in time. For travelers venturing to the island of Shikoku, specifically Ehime Prefecture, the cultural tapestry is woven from an ancient text known as the Iyo Fudoki. While the original scroll has been lost to the ravages of centuries, its surviving fragments provide a fascinating window into the mythology, geography, and spirit of ancient Iyo Province.
Today, we journey back to the 8th century to explore these lost chronicles and discover how they continue to shape the travel experience in modern Matsuyama and Dogo Onsen.
The Origins of the Lost Chronicle
In the year 713 AD, Empress Genmei issued an imperial decree ordering the compilation of Fudoki—reports on the wind and earth. These reports were intended to catalog the natural resources, land fertility, and oral traditions of the various provinces of Japan. While the complete texts of only five provinces remain (such as Izumo), the Iyo Fudoki exists today only as itsubun—scattered fragments cited in later medieval texts like the Shaku Nihongi.
Despite its fragmentary nature, the Iyo Fudoki is culturally monumental. It describes the region now known as Ehime (which translates beautifully to “Lovely Princess”). The text was more than a government census; it was an attempt to legitimize the spiritual power of the land. It connects the physical geography of the Seto Inland Sea with the divine hierarchy of the Shinto pantheon, grounding the region’s identity in the age of gods.
Legends of the Healing Waters
The most significant legacy of the Iyo Fudoki is its documentation of Dogo Onsen, widely cited as Japan’s oldest hot spring. Unlike other hot springs that claim purely geological origins, Dogo is steeped in divine intervention.
The Dance of Sukunabikona
According to the fragments, two major deities, Okuninushi (the Master of the Great Land) and Sukunabikona (the Small Deitity of Healing and Medicine), traveled across Iyo. During their journey, Sukunabikona fell gravely ill, appearing to be on the verge of death. Okuninushi, in a desperate bid to save his companion, carried him to the hot springs of Dogo.
After bathing in the revitalizing waters, Sukunabikona didn’t just recover; he was so energized that he leapt onto a stone and danced. This legendary stone, the Tama-no-ishi, remains a revered artifact at Dogo Onsen today. This story establishes the onsen not merely as a place of relaxation, but as a site of miraculous resurrection and divine healing.
Prince Shotoku’s Visit
Another fragment recounts the visit of the legendary Regent Prince Shotoku in 596 AD. The Iyo Fudoki reportedly contained the text of an inscription the Prince left behind, praising the sublime quality of the water and the camellia trees surrounding the spring. This establishes Dogo Onsen as a destination for the imperial elite over 1,400 years ago, creating a lineage of high-culture tourism that persists to this day.
Modern Culture: Living History in Matsuyama
Walk through the streets of Dogo today, and the Iyo Fudoki feels less like a dusty text and more like a living script. The town of Matsuyama has embraced these legends, weaving them into the fabric of daily life.
The centerpiece is the Dogo Onsen Honkan, a magnificent three-story wooden bathhouse built in 1894. Its labyrinthine corridors and traditional architecture served as a visual inspiration for Hayao Miyazaki’s Spirited Away. When you bathe here, you are literally soaking in the same waters mentioned in the ancient texts. The sound of the Toki-daiko (time drum) booming from the roof at dawn and dusk creates an atmosphere that transports visitors back to the Nara period.
Furthermore, the “Lovely Princess” moniker of Ehime is reflected in the local hospitality, or omotenashi. The region is famous for its citrus fruits, particularly mikan, which grow in the fertile soils described in ancient records. The blend of agricultural bounty and spiritual history makes Ehime a unique cultural hub in Shikoku.
Traveler’s Tips: Visiting the Land of Iyo
If you are planning a pilgrimage to the setting of the Iyo Fudoki, here is how to make the most of your trip:
- Visit the Tama-no-ishi: Located just north of the Dogo Onsen Honkan main building, you can see the stone where the deity Sukunabikona danced. Pouring water over the stone with a ladle is said to bring good health.
- Soak in the Kami-no-Yu: Inside the Honkan, try the “Bath of the Gods” (Kami-no-Yu). Be sure to observe traditional onsen etiquette—wash thoroughly before entering the water and keep your towel out of the bath.
- Explore Isaniwa Shrine: Located a short climb up a hill nearby, this shrine exemplifies the Hachiman architecture and offers a view over the town that helps you appreciate the geography described in the Fudoki.
- Try the Citrus: Don’t leave without tasting the local mikan juice or terrifyingly delicious mikan-flavored soft serve. It is the modern “fruit of the land” recorded in the province’s history.
