本章では，土器の在地・搬入などの性格づけについての，モデルを提示する。製作物としての土器の属性を，「いつ・どこで・だれが・なにを・なにで　つくったか」に区分して整理する。「いつ」は，時間の属性であり，「どこで」は空間的属性に含まれる。「だれが」は製作者，「なにを」は土器の系統，「なにで」は原料にそれぞれ関連する属性である。今回，問題とする在地土器，搬入土器の性格づけに関わる属性として，「どこで」つくられたか，「だれが」作ったか，「なにを」規範として作ったか，を取りあげ，概念的に区分し，そのあり得る組み合わせをモデルとして構築した。群馬県西部から東信地域においては，在地生産である焼町土器，在地において変形した勝坂系，同じく変形した大木系や阿玉台系土器が，それぞれ時期・遺跡によってその組成比を異にしながら，他系統共存のあり方を呈している。特に通時期的・汎地域的に主体となる土器型式が，主体的存在として卓越することはなく，強いて言えば，当該地域西側では焼町土器，中央部では勝坂系，東側では大木系・阿玉台系の比率が高くなる傾向が指摘できる。これら在地の土器に混じって，南東北地方～栃木県域の大木系土器，南関東や中部高地の勝坂系土器，越後地域の北陸系土器などが，外来系土器として搬入され，同時に在地で模倣生産されている。さらに，各系統の土器の間において，互いの要素を交換した折衷土器が作られている。これらの土器が在地なのか，搬入なのか，また在地または外地で作られたことが胎土分析などで確認されたとしても，自らのアイデンティティの共有する土器として作られていたのか，エキセントリックな欲求から製作されたのか，など多角的な視点から土器の系統を社会的システムのなかで理解しなければならない。さらにその土器がどのように製作され用いられ移動させられたのか，言ってみればいかなる社会的ニッチを持たされていたのか，について型式学的，さらには他の方面からの多様な検討を深めていく必要があろう。

This paper proposes a model for characterizing the locality, transportation and other features of pottery. The attributes of pottery as manufactured items are examined on the basis of time, place, manufacturer and manufactured item.The pottery covered in this study is Katsusaka, Atamadai, Daigi, Yakemachi, Hokuriku-region and Kasori-E type pottery dating from the middle stage through to the latter stage of Middle Jomon. They have been classified into three time periods.Pottery from archeological sites in Gunma Prefecture and the Kawarata Site in Nagano Prefecture were investigated as case studies and the component ratios of the different types of pottery among the number of individual pieces were examined. A study of Setchu (mixed-style) pottery was also conducted on the basis of pottery patterns. These investigations revealed that Middle Jomon pottery from Gunma Prefecture reflects the transportation of pottery from other regions and the movement of pottery manufacturers to the area from other regions.The three sites of the Kawarata Site, Shounan Site and the Hanageishinakayama-Rokutanda Site were studied in order to determine the component ratios of the different types of pottery. As for the locations of these sites, the Kawarata Site is located in Saku-gun in Nagano Prefecture, the Shounan Site on the western banks of the Tone River in the western part of Gunma Prefecture and the Hanageishinakayama-Rokutanda Site is located at the southwestern foot of Mount Akagi in the central part of Gunma Prefecture.The study showed clear differences in the component ratios of types of pottery at the three different sites. Yakemachi pottery accounted for nearly half of the pottery from the Kawarata Site dating from stage two of the second period, while Yakemachi pottery was found in small quantities at the two Gunma Prefecture sites.Items of mixed-style pottery were classified into one of two categories as the result of an examination of the types of pottery represented in the bases and which elements belonging to the different types are incorporated into which parts of the items, such as the opening and body. Thus, they were classified as being either locally produced mixed-style pottery or mixed-style pottery that was possibly manufactured in another region.A model for the movement of Jomon pottery was established by classifying items on the basis of region, origin of manufacturer and differences in their detail and then arriving at a description formed by the combination of these elements.
