| Outline of Final Research Achievements |
Jomon potteries were discovered at the Miyanna site in Sashima, Kamijima-cho, located in the Geiyo Islands. The upper Layer IV-1, contains pottery from the early to late Jomon period, while the lower layer IV-2, contains ridge-top pottery, pierced pottery, unmarked pottery and twining pottery. Twisted-pattern pottery was excavated in the upper part of Layer IV-2, while the rest was excavated in the middle or lower part of Layer IV-2. The fact that the pottery in Layer IV-2 does not contain any pressed patterned pottery reveals that the pottery in Layer IV-2 is from the initial stage to the early part of the pre-early Jomon period. As well as being the oldest Jomon pottery from the Geiyo Islands, it was also found to be Jomon pottery from a stage when there was no sea in the Seto Inland Sea. Topographical surveys, including various borehole investigations, were carried out, which also revealed changes in the topographical environment before and after the Jomon transgression.

| Academic Significance and Societal Importance of the Research Achievements |
芸予諸島だけでなく、瀬戸内海島嶼部で初めてとなる縄文草創期の土器であり、海のない時代の瀬戸内の縄文土器という点で新たな論点を提起した。隆帯文土器、刺突文土器、無文土器の年代的序列に関しては今後の検討課題であるものの、西日本における比較論において島嶼部への注意を喚起する資料である。同時に、多くの場合、地山層として掘り下げることがなかった花崗岩の砂礫層からの遺物検出であることから、今後の島嶼部での発掘調査に対して指針を与える研究ともいえよう。また「海のない瀬戸内」の景観は容易に想像できないがために一般の方々にも刺激的であり、社会的意義が高い。
