Jōmon period thumb|Potsherds from the Odai Yamamoto I site The oldest evidence of pottery in Japan was found at the Odai Yamamoto I site in the town of Sotogahama in the northwestern part of the prefecture. The relics found there suggest that the Jōmon period began about 15,000 years ago. By 7,000 BCE, fishing cultures had developed along the shores of the prefecture which were three meters higher than the present day shoreline. Around 3,900 BCE, the settlement at the Sannai-Maruyama Site in the present-day city of Aomori began. The settlement shows evidence of the wide interaction between the site's inhabitants and people from across Jōmon period Japan, including Hokkaido and Kyushu. The settlement of Sannai-Maruyama ended around 2300 BCE due to unknown reasons. Its abandonment was likely due to the population's subsistence economy being unable to result in sustained growth, with its end being spurred on by the reduced amount of natural resources during the neoglaciation. The Jōmon period continued up to 300 BCE in present-day Aomori Prefecture at the Kamegaoka site in the city of Tsugaru where the Shakōkidogū was found.
