 note = {application/pdf, 大宰府は九州北部の福岡平野と筑紫平野を繋ぐ溝状の地峡帯に展開し、企画性のある方眼グリット状に展開する道路を伴うため条坊プランが存在したと考えられている。文献には「左郭」「右郭」の表記があり、都城的なシステムが存在したことが考えられる。八世紀の大宰府の様相は、『万葉集』などによれば中央官人達にとっては「天ざかる鄙」の地であっても「天下の一都会」と表現され、発掘された遺構からは集住性や京師に類似した墳墓域が認められるため、都市性を設えた空間であったと考えられる。
大宰府では調査で明らかにされた官衙・集住域・山城・寺院の各遺構を、八世紀から九世紀にかけての時間軸上での変遷を同時的に概観するとき、各カテゴリーに共通して八世紀後半に向かっての隆盛、九世紀に入っての潜在化と変容が認められる。九世紀には西海道各国の国庁が礎石採用・瓦所要に変化し壮麗化を果たし、工業生産の地域間分業の構造主体が国を超えて移動するなど大きな潮流の変化が見られる。そういった意味では抽出された大宰府での遺構動態の画期は、古代西海道という地域動態の変容の中で位置づけられる可能性がある。大宰府政庁の現位置での廃絶時期は一一世紀中頃と想定され、都市域である条坊機能の終焉は一二世紀前半頃に想定されている。, Dazaifu is located on a trough-like isthmus in northern Kyushu that links the Fukuoka plain and the Tsukushi plain. The existence of roads constructed in a planned grid pattern suggests the existence of a grid plan. Documents describe a “left block” and “right block,” and it is believed that it followed the style of a walled capital city. The Dazaifu of the 8th century is described as “one of the cities of the land” in the Man'yoshu and other written sources even though for officials from the central government it was “provincial and far from the capital, ”. The discovery of a sizeable resident population and tombs similar to those in the capital from excavated remains suggests that it was a space with urban characteristics.
When reviewing simultaneously the remains of government offices, residential districts, hillside fortifications and temples uncovered by surveys undertaken at Dazaifu to identify changes that occurred from the 8th century through the 9th century, in each category we find similar evidence of prosperity near the second half of the 8th century and latency and transformation in the early 9th century. In the 9th century, the provincial offices of the provinces in Saikaido (present-day Kyushu) were grand buildings with foundation stones and tiles. From the structure of industrial production which was divided among the regions and movement between the provinces it is evident that a considerable tide of change was taking place. In this sense, it is possible to place the dynamic relics extracted from Dazaifu within the period of transformation of the regional dynamism of ancient Saikaido. It is assumed that the Dazaifu government situated at its present location was abolished in the middle of the 11th century and that the demise of the distinctive grid pattern took place around the first half of the 12th century.},
