The Ōdai Yamamoto I Site (Japanese: 大平山元I遺跡, Hepburn: Ōdaiyamamoto ichi iseki) is a Jōmon archaeological site in the town of Sotogahama, Aomori Prefecture, in the Tōhoku region of northern Japan. Excavations in 1998 uncovered forty-six earthenware fragments which have been dated as early as 14,500 BCE (ca 16,500 BP); this places them among the earliest pottery currently known. As the earliest in Japan, this marks the transition from the Japanese Paleolithic to Incipient Jōmon. Other pottery of a similar date has been found at Gasya and Khummi on the lower Amur River. Such a date puts the development of pottery before the warming at the end of the Pleistocene.

Ōdai Yamamoto I Site in the context of Aomori Prefecture
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.
