Aomori Prefecture is famous for various ruins
that have been unearthed throughout the prefecture, dating back over 10,000
years to the hunter-gatherer Jōmon era. Tsugaru City boasts its share
of those ruins, including the Kamegaoka Ruins, where the Shakōki-Dogū
clay figure was discovered, the Ishigami Ruins, the Kakegawa Ruins and
the Tagoyano Shell Mound.
The Jōmon relics unearthed in Tsugaru City come from the late and final Joumon periods, and include vessels made with bamboo, red and black lacquer, and glass balls. They are very sophisticated and have a high level of finish, a testament to the excellent artistry of the Jōmon peoples.
In 1944, the Committee for the Protection of Cultural Properties in Japan designated the Kamegaoka Relics and the Tagoyano Shell Mound as sites of historical importance. While
both sites can be visited in person (see right map), the contents of excavation are on display at the Karuko Archaeological Hall
next to Tsugaru City Hall.
