Jōmon Prehistoric Sites in Northern Japan in the context of ICOMOS

Aomori Prefecture (青森県, Aomori-ken; Japanese pronunciation: [a.oꜜ.mo.ɾʲi, a.o.mo.ɾʲiꜜ.keɴ]) is a prefecture of Japan in the Tōhoku region. The prefecture's capital, largest city, and namesake is the city of Aomori. Aomori is the northernmost prefecture on Japan's main island, Honshu, and is bordered by the Pacific Ocean to the east, Iwate Prefecture to the southeast, Akita Prefecture to the southwest, the Sea of Japan to the west, and Hokkaido across the Tsugaru Strait to the north. Aomori Prefecture is the eighth-largest prefecture, with an area of 9,645.64 km (3,724.20 sq mi), and the 31st-most populous prefecture, with more than 1.18 million people. Mount Iwaki, an active stratovolcano, is the prefecture's highest point, at 1,624.7 m (5,330 ft).

Humans have inhabited the prefecture for at least 15,000 years, and the oldest evidence of pottery in Japan was discovered at the Jōmon period Ōdai Yamamoto I Site. After centuries of rule by the Nanbu and Tsugaru clans, the prefecture was formed out of the northern part of Mutsu Province during the Meiji Restoration in the 19th century. The entire Tōhoku region, including Aomori Prefecture, experienced significant growth in population and economy until the late 20th century, when a significant population decline began. Though the prefecture remains dominated by primary sector industries, especially apple orchards, it also serves as a transportation and logistics hub due to its location. Additionally, it is the largest producer of black garlic in Japan. Tourism is also a significant part of the prefecture's economy, especially due to the Jōmon Prehistoric Sites in Northern Japan and Shirakami-Sanchi World Heritage Sites.

The Sannai-Maruyama Site (Japanese: 三内丸山遺跡, Hepburn: Sannai-Maruyama iseki) is an archaeological site and museum located in the Maruyama and Yasuda neighborhoods to the southwest of central Aomori City in Aomori Prefecture in northern Japan, containing the ruins of a very large Jōmon period settlement. The ruins of a 40-hectare (400,000 m; 99-acre) settlement were discovered in 1992, when Aomori Prefecture started surveying the area for a planned baseball stadium. Archaeologists have used this site to further their understanding of the transition to sedentism and the life of the Jōmon people. Excavation has led to the discovery of storage pits, above ground storage, and long houses. 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, and a UNESCO World Heritage Site as part of the Jōmon Prehistoric Sites in Northern Japan collection in 2021. Today the public can visit the site, its various reconstructions of Jōmon structures, and a museum that displays and houses artifacts collected on the site, which have collectively been designated an Important Cultural Property of Japan.
