Since 1997, the Idojiri Archaeological Museum has been creating an image database of excavated materials, mainly related to Jomon potteries and clay figurines. This booklette is the Vol.7 of the Idojiri's Jomon Pottery series that has been published based on the imagedatabase and contains 10 major Jomon potteries that were uncovered at the Shimohara ruins, Ikukubo ruins and Nakahara ruins. These ruins are located in the southwest foot of Yatsugatake mountains where many other Jomon ruins have been excavated. So this area is often called like "The Jomon kingdom of Yatsugatake highland".The commentaries were written by Takashi Komatsu under the supervision of Seiji Higuchi of the Idojiri Archaeological Museum, who was in charge of the survey.
