Shitanoya Archaeological Site: A 5,000-Year-Old Jōmon Village in Tokyo
Tucked away in a quiet residential neighborhood of Nishitokyo City, just a short train ride from the bustling heart of Shinjuku, lies one of the most remarkable archaeological discoveries in the Tokyo metropolitan area. The Shitanoya Archaeological Site (下野谷遺跡, Shitanoya Iseki) preserves the remains of a large-scale Jōmon period settlement that thrived for over a thousand years, roughly 5,000 to 4,000 years ago. Designated as a National Historic Site in 2015, Shitanoya offers visitors a rare chance to walk directly above the traces of an ancient community that once flourished along the banks of the Shakujii River.
Unlike many archaeological sites in Japan's rapidly developed urban areas, which were lost to construction after being excavated and recorded, Shitanoya has survived remarkably intact beneath the modern cityscape. This makes it an extraordinary destination for anyone interested in Japan's deep prehistoric heritage — and a peaceful urban oasis in its own right.
What Is the Shitanoya Archaeological Site?
The Shitanoya site is a large ring-shaped settlement, known in Japanese as a kanjō shūraku (環状集落), dating primarily from the Middle Jōmon period (approximately 3,500–2,500 BCE). The settlement covers an impressive area of roughly 134,000 square meters — equivalent to about three Tokyo Domes — spanning parts of Higashi-Fushimi 2-chōme, 3-chōme, and 6-chōme in Nishitokyo City.
The site consists of a western settlement with a diameter of about 150 meters, featuring pit dwellings arranged in a circle around a central plaza containing burial pits. Raised-floor buildings, thought to be granaries or storehouses, were positioned in a semicircular band between the dwellings and the burial area. Across a small valley to the east, a second ring-shaped settlement of similar age has been identified, forming what archaeologists call a "double ring settlement" (sō kanjō shūraku), a hallmark of a major regional hub.
Excavations — which have covered only about one-tenth of the total site — have already revealed over 450 dwelling foundations along with vast quantities of pottery and stone tools. The pottery styles found here, particularly Katsuzaka-type and Kasori E-type wares, indicate that the community was continuously inhabited for approximately 1,000 years. Some pottery shows influences from as far away as southern Tōhoku and the Kōshin'etsu region, suggesting extensive networks of trade and cultural exchange.
Why Was Shitanoya Designated a National Historic Site?
Ring-shaped settlements from the Middle Jōmon period are found widely across the Kantō and Kōshin'etsu regions. Among the dense cluster of such sites on the Musashino Plateau and Tama Hills, Shitanoya stands out for both its exceptional scale and the outstanding state of preservation of its remains.
The Japanese government recognized several key factors when granting Shitanoya its designation in March 2015, with an expanded area added in March 2022. First, the site is one of the largest Middle Jōmon settlements in the entire southern Kantō region. Second, the double ring settlement structure indicates it served as a major hub for communities along the Shakujii River basin. Third, and perhaps most remarkably, such a large-scale settlement has survived nearly intact in the middle of a densely urbanized area of the Tokyo metropolis — an extremely rare circumstance that makes its preservation all the more valuable as a cultural heritage for future generations.
Highlights and Things to See
Shitanoya Archaeological Park (Shitanoya Jōmon no Sato)
Part of the site has been developed as Shitanoya Archaeological Park, located on a gentle rise about 400 meters south of Higashi-Fushimi Station. The park serves a dual purpose: preserving the archaeological remains underground while providing an open, green space for visitors and local residents alike.
In 2023, the park underwent significant enhancements. Two pit dwellings have been reconstructed using earth-covered roofs, allowing visitors to step inside and experience the surprisingly comfortable living spaces of Jōmon people — cool in summer and warm in winter, with a central hearth for cooking and warmth. Reconstructed burial pits and a pottery disposal area give further insight into how the settlement was organized.
The entrance zone features detailed interpretation panels explaining the site's history and Jōmon-period daily life, along with an aerial photograph showing the full extent of the settlement and a three-dimensional scale model. Throughout the park, chestnut, walnut, oak, and other trees that were important to Jōmon people have been planted, recreating elements of the landscape they would have known.
VR Shitanoya Jōmon Museum App
For a truly immersive experience, visitors can download the free "VR Shitanoya Jōmon Museum" smartphone app, developed by Nishitokyo City. Using the app on-site, you can view computer-generated reconstructions of the Jōmon village overlaid on the actual landscape. Features include an aerial view of the reconstructed village, 360-degree panoramas of daily life inside and outside the dwellings, animations of gathering, hunting, and river trade activities, and an interactive Jōmon-themed quiz.
Jōmon Mascot Characters: Shīta and Nōya
The site has its own lovable mascot characters, "Shīta" and "Nōya," whose names combine to form "Shitanoya." Bronze monuments of the mascot family — Shīta, Nōya, and their parents Gin and An — stand at the south exit plaza of Higashi-Fushimi Station, welcoming visitors and guiding them toward the archaeological park.
Seasonal Events
Each autumn, the park hosts the popular "Jōmon no Mori no Aki Matsuri" (Autumn Festival of the Jōmon Forest), a community-driven event where visitors can try their hand at Jōmon-era activities such as fire-making, cord-weaving, and archery. The festival draws large crowds each year and offers a wonderful opportunity to engage with prehistoric culture in a hands-on way.
Nearby Attractions
The area around Higashi-Fushimi Station offers several other worthwhile stops that pair well with a visit to the Shitanoya site.
Higashi-Fushimi Inari Shrine
Just a few minutes' walk north of the station, Higashi-Fushimi Inari Shrine was established in 1929 when spirits from Kyoto's famous Fushimi Inari Taisha were enshrined here at the request of Inari devotees in the Kantō region. The shrine features striking vermilion buildings set amid lush greenery and a labyrinth of torii gates behind the main hall, reminiscent of the thousand torii gates of its Kyoto counterpart. It has been selected as one of the "New 100 Views of Tokyo."
Musashiseki Park
A short walk east along the Shakujii River, Musashiseki Park is a peaceful green space centered around Fujimi Pond. The park offers walking trails, boat rentals, and a chance to enjoy the natural riverside scenery of the Musashino Plateau.
Shakujii River Greenway
The banks of the Shakujii River, which played a vital role in sustaining the ancient Shitanoya community, provide a lovely walking and cycling path connecting several parks and green spaces in the area. Cherry blossoms in spring and autumn foliage make this a particularly scenic route.
Understanding the Jōmon Period
The Jōmon period (approximately 14,000 BCE – 300 BCE) is one of the longest cultural eras in human history and represents a globally unique example of a complex, sedentary hunter-fisher-gatherer society. Rather than relying on agriculture, Jōmon people sustained themselves through fishing, hunting, and gathering the abundant resources of Japan's forests and coastlines.
The period gets its name from the distinctive cord-marked patterns (jōmon) found on its pottery — some of the oldest ceramics in the world. During the Middle Jōmon period, when the Shitanoya settlement flourished, populations reached their peak, elaborate pottery with dramatic "flame-style" decorations was produced, and large, organized settlements with communal plazas and ritual spaces became widespread across the Kantō and Chūbu regions.
In 2021, UNESCO inscribed the "Jōmon Prehistoric Sites in Northern Japan" as a World Heritage Site, bringing international attention to this fascinating chapter of Japan's deep past. While the Shitanoya site is not part of that inscription, it represents the same cultural tradition at its zenith in the southern Kantō region.
