The ruins of Sannai-Maruyama
Today we visit the ruins of Sannai Maruyama in Aomori. Discovered in 1992, the Sannai Maruyama Archaeological Site (三内丸山遺跡) is the largest and one of the most complete and best preserved Jomon Period (13000-300 BC) villages in Japan.
Morioka to Aomori
We were thoroughly refreshed from our previous day at Jōdogahama beach in Iwate. The day was bright and sunny as we walked to Morioka Station to catch the train to Aomori. As we entered the JR station, it was still decorated, in view of the just passed Tanabata celebrations.Nebuta Museum to witness the amazing floats.
As we entered the giant hall in Jomon Jiyukan, the volunteers at the reception helped us out with the information about the heritage site. They provided us with a guided map of the area. Beside the reception, one can also find dresses from the Jamon period. Visitors are free to try on these Jomon period clothing, along with a few tools of the era. I tried out a fisherman’s dress and I believe I would have fit right in into this traditional society 🙂
The Sanmaru museum exhibits objects excavated from the excavation site and explains about the people who lived during the Jomon Period. The Jomon period encompasses a large expanse of time, constituting Japan’s Neolithic period and the museum exhibits approximately 1,700 artifacts excavated from the Sannai-Maruyama site.
A dimly lit path led us towards a life-sized figure of a young boy with his Inu(dog) who pointed us towards the cases of historical findings from the Jomon period.
Jomon no Kokoro
The first section of the Sanmaru Museum is called the Jomon no Kokoro (heart of the Jomon Period). This area displays various excavated items including a large number of pottery, stone artifacts, personal ornaments, clay figures, earthenware, wooden utensils, bone tools and small knitted baskets called “Jomon pochette” from the Jomon period.
The Jomon people of Sannai Maruyama
As we moved further, we were in the Jomon-jin no Kurashi wo Himotoku (Lifestyle of the Jomon Period people) section. Here life-sized figurines are used to reproduce the Jomon daily life, based on excavated objects. The people in the early Jomon period frequently traveled from one place to the next while engaged in camping and nomadic life. The Jomon people primarily belonged to a hunter-gatherer culture.
A brief history of Jomon People of Sannai-Maruyama
The Jomon period experienced a large-scale climate change since it extended for a long period of 10,000 years. The Sannai-Maruyama Ruins are the largest ruins of a Jomon-period (about 10,500-300 BC) village in Japan, and are estimated to date from 4,000 to 5,500 years ago. The Japanese archipelago is extremely elongated from north to south and its topography varies considerably; therefore, regional differences in the climate and vegetation were large during the Jomon period as is today. As a result, the cultural style of the Jomon period is not uniform both historically and regionally and it came to take many different forms.
There have been previous excavations around the Sannai-Maruyama site between 1953 to 1967. These excavations involved teams from Keio University and the Board of Education of Aomori City. In 1976 and 1987, the Board of Education of Aomori Prefecture and Aomori City also conducted further excavations on the southern part of the site.
However, the major breakthrough for the site came in 1992 while excavating during a pre-construction phase for a baseball stadium. This excavation uncovered how large Sannai Maruyama was as well as a large amount of artifacts.
After the excavation and study of the site, the village was reburied with earth and a number of reconstructed pit dwellings, long houses and a large tower were built on top. Visitors can enter the reconstructions, some of which are quite large, as well as see a few of the original excavation sites around the grounds.
A large amount of potsherds and stone implements, clay figurines, jade beads, etc. were disposed together with the soil and formed a mound for over 1000 years. You can see its cross-section here. X-ray analysis shows that the jade excavated at ‘Sannai-Maruyama Site’ in Aomori Prefecture is from Itoigawa; therefore, it is assumed that the Jomon people also traded among themselves over the wide area.
These findings demonstrate a change in the structure of the community, architecture, and organizational behaviors of these people. Because of the extensive information and importance, this site was designated as a Special National Historical Site of Japan in 2000.
Sannai Maruyama was first settled around 3900 BCE. At that time it was inhabited by hunters and gatherers only. Over this period of time, the site changed from a seasonal camp, to the home of a more mobile society, and finally to a settled village. Evidence of this sedentary lifestyle can be found in the the changes in their storage facilities.
The earliest pit dwellings at Sannai Maruyama were during the Early Jomon period, built between 5900 and 5400 years ago. At that time, Sannai was comparatively small and simple, a collection of pit dwellings. The first settlers on the site lived in pit houses. These dwellings typically were about 10 feet in diameter. The floor was dug below the ground level. A hearth was located in the its center. At least 550 pit-dwellings have been discovered so far and 15 have been reconstructed. Some of the pit houses seen at Sannai Maruyama were simple thatched-roof semi-subterranean houses, like this reconstruction. To make this bark-thatched pit dwelling, a pit was excavated into the ground and a bark or wood branches were assembled over the top forming a cone like structure.
Over time the thatched pit dwelling was replaced with a sturdier structure as shown below. Like the thatched huts, the floor of a pit dwelling was dug into the ground. Supporting posts were placed at the corners and the walls and roof were built and roofed with thatch. The average size of these pit dwelling is between three and four meters in diameter.
Initially they used to store food in underground pits, which allowed them to hide it when they left the site since the occupants were not yet living a sedentary lifestyle. With time, the storage features changed from these underground pits to elevated granaries around 2900 BC. These buildings were built higher than the ground level and were specifically used as storage facilities.
As the community became sedentary, long houses began showing up around this time. Long houses were large, oval-shaped structures. The longest one found at the site was 32 meters (105 feet) long. Scholars believe long houses were used for meeting places, workshops, or living space. Pit houses were still being inhabited for individual dwelling at the same time that long houses started to come up on the landscape.
With a stable living style, also, there appeared one of Sannai Maruyama’s most famous structures, the large six-pillared building, was built around 2,600 BC. This structure consisted of six large pillars that are believed to have held up platforms. Each one of these pillars was around 1 meter in diameter and was placed exactly 14 ft apart. This large post like platform was certainly used as a watchtower.
Burials at Sannai Maruyama took three forms: jar burials, pit burials, and stone circle burials. Large jars have been discovered near the pit dwelling clusters. These are assumed to be burials, although human bones have not been preserved within them, on the basis of similar burials found in later Jomon sites such as Yoshinogari. Jar burials have been dated to the Middle Jomon period, from 5400-4300 years ago. The second form of burial was of adults aligned in rows along the sides of long roadways extending from the center of the settlement towards the outside. Finally as shown below, stone circle arrangements have also been found at Sannai Maruyama, which included adult burials.
By now we were extremely dehydrated. The harsh sun had taken its toll and we dragged ourselves into the safety of the Jomon Jiyukan.
The Sannai Maruyama site was designated as a special historical site by the Japanese government in November 2000. Today the public can visit this site and explore its many reconstructions. The site also features a Theater, a workshop and a gift shop. If you are in love with history do not miss this site. Even though at present, most of the excavated items have been reburied for preservation, the excavation sites and artifacts on display will giving you a feel of life in those ancient times.
