An Examination of Provincial policies in the Early phase of prince Nagaya's rule, with Special preference to Government offices and Temptes

为了从考古学的角度研究这一问题，本文考察了田河町城堡、田河町废弃寺、岛宅宫、大在府、筑地观音寺以及周围的寺庙、政府和省政府机关以及平房宫的建造和翻新的年表。以前的研究分别考察了东北的田州、班道的下辅八世、西海道的大在府等遗址，但本文以长谷太子的治省政策为背景，重新评估了长谷太子的早期统治。首先，在分析田合和大在府二世的成立日期的基础上，提出它们都是在约罗四世的林户和埃米西起义之后作为新的省级控制政策的一部分而建立的。这里还对其他主要政府机构的形成进行了一些讨论。其次，考察了日本三大祭祀神庙之一的下助靖国寺与官府寺庙并列的时期，确认了当时日本对建立田州废墟、筑地观音寺等官方省级寺庙的政策和宗族寺庙合并政策的认真考虑。第三，虽然这些省级政策以及佛教寺庙和其他设施的建立直接始于与林户和埃米什战争有关的边境政策，但它们不仅仅是边境政策，还可以被视为保卫王国的国家措施的一部分。长屋亲王的这些政策是藤原和富仁政策的延续，但省政府的重大进步和长屋亲王领导下的佛教寺庙的建立，为中央集权的国家制度奠定了基础。

In an attempt to investigate this problem from an archaeological perspective, this article looks at the chronology of the construction and renovation of Taga-jo Castle, the Taga-jo Abandoned Temple, Shimotsuke Yakushiji, Dazaifu, Tsukushi Kanzeonji, as well as surrounding temples, government and provincial offices, and the Heijo Palace. Previous research has looked separately at sites such as Taga-jo in the Tohoku, Shimotsuke Yakushiji in the Banto, and Dazaifu in the Saikaido, but this article reevaluates the early rule of Prince Nagaya against the background of his policies regarding the provinces.The article argues three points. First, on the basis of an analysis of the dates of establishment of Taga-jo and Dazaifu II, it is proposed that they were both established as part of a new policy of provincial control following the Hayato and Emishi revolts in Yoro 4. There is also some discussion here of the formation of other major government offices. Secondly, an examination is made of the period when Shimotsuke Yakushiji, one of the three ordination temples of Japan, ranked with government temples and it is confirmed that serious consideration was given to the contemporary policies of the establishment of official provincial temples such as the Taga-jo Abandoned Temple and Tsukushi Kanzeonji and the clan temple policy of temple mergers. Thirdly, although these provincial policies and the establishment of Buddhist temples and other facilities had their direct beginning in frontier policies associated with the Hayato and Emishi wars, they were not simply frontier policies but can be seen as part of national measures for the defense of the realm. These policies of Prince Nagaya were a continuation of those of Fujiwara no Fuhito, but the substantial advances in provincial government and the establishment of Buddhist temples under Prince Nagaya built the basis for a centralized state system.
