Obsidian was one of the materials transported across the Tsugaru Strait in prehistoric times. Source analysis of obsidian can reveal that it was finally transported to the site, but it does not demonstrate that the human groups who used them migrated across the sea directly. Therefore, to prove the human movement across the Tsugaru Strait, we attempt to apply a multiple approach combining the typological sequence of pottery, change in number of pit-houses and the source analysis of the obsidian found in Kamikita and Hachinohe areas located on the northern tip of Honshu. Firstly, we argue that Teruya Esaka, a leading archaeologist of the Initial Jomon period studies, claimed the one-sided diffusion-model from Hokkaido to Honshu in 1950’s. Chronological studies of the Initial Jomon pottery in the northern Tohoku region was likely to be strongly affected by his perspectives, but the recent studies of wider-area chronology would be based on interaction model between pottery types. Secondly, we clarified two significant stages in the diachronic change of pit-house numbers based on wider-area pottery chronology from S4 to S8 in the Initial Jomon Period: the decline stage continued from S4 (Monomidai-type) to S5 (Torikisawa-type) and the stable stage (S7). Especially in the Monomidai-type phase of S4, it is noteworthy that an obsidian tool sourced from Honshu is found in the southwestern Hokkaido, while a Hokkaido-sourced obsidian tool is found in Kamikita area. Based on our studies, we can deduce that a two-way interaction route across the Tsugaru Strait was established in this phase. Considering the drastic increase of pit-houses and similar pottery to Honshu found at Nakano A site (Hakodate city) of Hokkaido, we would like to hypothesize that human migration from Honshu to the southwestern Hokkaido occurred in this phase. On the contrary, it is difficult to assume a dynamic interaction at S7 phase when the largest number of Hokkaido-sourced obsidian was reported in the Hachinohe and Kamikita areas. Further studies are necessary to explore the Monomidaitype phase of S4 to prove our hypothesis.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162440","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NEGISHI, Yo"}]},{"nameIdentifiers":[{"nameIdentifier":"162441","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IKEYA, Nobuyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"162442","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SATO, Hiroyuki"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00079710","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院人文社会系研究科・文学部考古学研究室"}]},"item_4_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11190220 ","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18803784","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Department of Archaeology Faculty of Letters, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"根岸, 洋"}],"nameIdentifiers":[{"nameIdentifier":"162437","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池谷, 信之"}],"nameIdentifiers":[{"nameIdentifier":"162438","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤, 宏之"}],"nameIdentifiers":[{"nameIdentifier":"162439","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-12"}],"displaytype":"detail","filename":"kouko3302.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kouko3302.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/54594/files/kouko3302.pdf"},"version_id":"bd2d250c-9f1e-4c79-b00f-904ef88cbcce"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"上北・八戸地域から出土した縄文早期の黒曜石製石器群の産地推定と考察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"上北・八戸地域から出土した縄文早期の黒曜石製石器群の産地推定と考察"}]},"item_type_id":"4","owner":"1","path":["8478","8477"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-10-12"},"publish_date":"2020-10-12","publish_status":"0","recid":"54594","relation_version_is_last":true,"title":["上北・八戸地域から出土した縄文早期の黒曜石製石器群の産地推定と考察"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-19T04:32:13.314089+00:00"}
