Ayaori Shinden Site: A 6,000-Year-Old Jōmon Village in the Misty Tōno Basin
Tucked away in the highland basin of Tōno, in eastern Iwate Prefecture, lies one of Japan's most quietly remarkable archaeological treasures: the Ayaori Shinden Site (綾織新田遺跡). Around 6,000 years ago, on a sunlit terrace overlooking the Sarugaishi River, a community of early Jōmon people built a thriving village of unusually large dwellings, crafted exquisite stone earrings, and arranged their homes in a sweeping circle around a central plaza. Designated a National Historic Site in 2002, Ayaori Shinden offers a rare glimpse into a moment when prehistoric communities in northeastern Japan were beginning to organize themselves on a larger, more sophisticated scale.
A Window into Early Jōmon Life
The Jōmon period (c. 13,000–400 BCE) is famous for its hunter-gatherer culture, distinctive cord-marked pottery, and remarkably long stretches of peaceful, settled living. Ayaori Shinden belongs to the early Jōmon period, dating from roughly the latter part of the 5th millennium BCE to the early 4th millennium BCE, when the climate of northeastern Japan favored rich oak and chestnut forests, salmon-filled rivers, and abundant wild game.
The site sits on a river terrace at about 270 meters above sea level on the left bank of the Sarugaishi River, a tributary of the Kitakami. This was prime real estate in prehistoric terms: high enough to escape flooding, close enough to water and forest resources, and within an inland basin shielded from coastal storms. It is no coincidence that Tōno, even thousands of years later, remained a crossroads of culture and commerce in northern Japan.
Discovery and Excavation
The site came to light through a fortunate coincidence. In 1997, plans to develop an industrial site prompted the Tōno City Board of Education to conduct preliminary trenching and full-scale excavation. What emerged from beneath the soil was far more important than anyone had anticipated: a planned community with unusually large pit-dwellings, sophisticated spatial organization, and a wealth of finely worked artifacts.
Recognizing the site's significance, Tōno City decided in the early 2000s to preserve rather than develop the land. The site was acquired for public ownership in 2003 and carefully reburied to protect the fragile remains beneath. Today, an interpretive sign marks the site, while the excavated artifacts are conserved and displayed nearby in central Tōno.
Why It Was Designated a National Historic Site
Ayaori Shinden was designated a National Historic Site (国指定史跡) by the Agency for Cultural Affairs on December 19, 2002. The designation rests on three remarkable findings.
An Early Example of a Large-Dwelling Settlement
Archaeologists uncovered seventeen large pit-dwellings arranged radially around a central plaza, with smaller pit-dwellings, storage pits, refuse pits, and even a road-like depression extending about 50 meters down the western slope. The large dwellings are rectangular in plan, measuring 4 to 6 meters across the short axis and 8 to 14 meters along the long axis, with multiple hearths inside and clear evidence of repeated rebuilding and expansion. Several have ramps or step-like entrances facing the plaza.
This is one of the earliest known examples in Japan of a Jōmon village built around large, communal-scale dwellings—a settlement form that would become more common in the later early Jōmon period and beyond. As such, the site is invaluable for understanding how Jōmon society began to develop more complex social organization.
A Treasury of Daigi-Style Pottery
The pottery recovered from Ayaori Shinden belongs to the Daigi style (大木式土器), the dominant ceramic tradition of the early Jōmon Tōhoku region, named after the Daigi shell mound in Miyagi. Vessels of Daigi types 2, 3, and 4 were found together in significant quantities—an exceptionally rare combination that allows specialists to trace stylistic transitions across generations and refine the chronology of the early Jōmon period.
One of Japan's Greatest Finds of Slit Earrings
The site's most striking artifacts are its ketsu-jō jishoku (ケツ状耳飾り)—small, ring-shaped ear ornaments with a single slit, worn through the earlobe. Fifty of these earrings, all carved from talc (a soft, soapy mineral), were unearthed at Ayaori Shinden, ranking among the largest such finds in all of Japan. Because raw talc was also recovered, archaeologists are confident that the earrings were manufactured on site—evidence of a specialized craft tradition. Stone rods, stone swords, and unusual ritual stone tools were also found, suggesting that the community engaged in complex ceremonial activities.
Highlights and What to Look For
Because the site itself has been carefully reburied to protect its archaeological layers, visitors today see a peaceful grassland marked by an interpretive panel rather than visible foundations or reconstructions. The real visual treasures are displayed in the city center.
The Talc Ear Ornaments
Holding the gaze of any visitor at the Tōno Machinaka Doki-Doki-kan museum are the small, pale, crescent-shaped earrings of talc. Their craftsmanship is astonishingly fine for an age before metal tools, and their sheer abundance at Ayaori Shinden suggests both a flourishing local workshop and the social importance of personal adornment in this community.
The Pottery
The decorated Daigi-style vessels on display reveal the artistic sensibility of early Jōmon people: bold rim decorations, sweeping cord-marked patterns, and a feel for sculptural form that places this culture among the world's most distinctive ceramic traditions.
The Setting Itself
Even though the foundations are unseen, walking the quiet terrace and looking down to the Sarugaishi River below offers a moment of contemplation. The same wind, the same river, the same line of mountains greeted those who lived here six millennia ago.
Visiting the Site
The Ayaori Shinden Site is located in Ayaori-chō, on the western edge of central Tōno. The site is publicly accessible and free to visit, but please note that the excavated remains have been reburied for preservation. There is an interpretive panel on site, but no reconstructed buildings or visitor facilities. We strongly recommend pairing a visit to the site with a stop at the Tōno Machinaka Doki-Doki-kan museum, where the artifacts are displayed.
Tōno Machinaka Doki-Doki-kan
Housed in a charming, restored traditional storehouse in central Tōno, this small but excellent museum displays the talc ear ornaments, Daigi-style pottery, and other artifacts excavated from Ayaori Shinden, alongside finds from the Kanadori Site (one of Japan's oldest known Paleolithic sites) and other local excavations. Admission is free.

Surrounding Attractions
Tōno is one of Japan's most evocative cultural destinations—the legendary heartland of Tōno Monogatari (The Legends of Tōno), the seminal 1910 collection of folk tales compiled by the folklorist Yanagita Kunio. A visit to Ayaori Shinden pairs beautifully with a longer stay exploring the surrounding countryside.
Tōno City Museum
Just a short walk from the Doki-Doki-kan, the Tōno City Museum offers immersive exhibitions on local folk traditions, the world of Tōno Monogatari, and rural mountain life. It is the ideal companion to the archaeological collection.
Denshōen Folk Village
An open-air folk museum featuring traditional magariya L-shaped farmhouses, in which people and horses once lived under the same roof. Visitors can experience folk crafts, taste local cuisine, and walk among ancient stone oshira-sama deity figures.
Kappa-buchi Pool
A small, mossy pool behind Jōken-ji Temple where, according to local tradition, mischievous water spirits called kappa are said to live. A tongue-in-cheek "kappa fishing license" is even available in town for visitors who want to play along.
Hariyama Site
Another nationally designated Jōmon site within Tōno City, dating to the middle and late Jōmon periods. Together with Ayaori Shinden, it tells a remarkable story of long-term human habitation in the Tōno basin.

Q&A
- Can I see the actual pit-dwellings or excavation pits today?
- No. The excavated archaeological layers have been carefully reburied to protect them for future generations. On site you will find an interpretive panel and a peaceful terrace, while the artifacts themselves are displayed at the Tōno Machinaka Doki-Doki-kan museum in the city center.
- Why are the talc ear ornaments so important?
- Fifty slit ear ornaments were recovered, ranking the site among the largest such finds in Japan. The presence of unworked talc raw material indicates that the earrings were produced at the site itself, making Ayaori Shinden a rare window into specialized Jōmon craft production.
- How old is the site?
- The settlement dates to the first half of the early Jōmon period—roughly 6,000 years ago. The pottery from the site belongs to Daigi types 2, 3, and 4, three successive ceramic styles of the early Jōmon Tōhoku region.
- How do I get to Tōno from Tokyo?
- Take the Tōhoku Shinkansen from Tokyo Station to Shin-Hanamaki Station (about 3 hours), then transfer to the JR Kamaishi Line for Tōno Station (about 1 hour). Tōno is a wonderful base for exploring inland Iwate.
- Is the site connected to the UNESCO Jōmon World Heritage listing?
- Ayaori Shinden is not part of the "Jōmon Prehistoric Sites in Northern Japan" UNESCO World Heritage inscription, which centers on Hokkaido and northern Tōhoku. However, it is a nationally designated historic site of comparable scholarly importance, and visiting it deepens any traveler's understanding of the broader Jōmon world.
