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探讨这一问题，本文考察了多加城城、多加城废弃寺、下津屋寺、大宰府、筑城观藏寺以及周围的寺庙、政府和地方办公室、平城宫的建造和翻新的年表。以前的研究分别考察了东北的多加町、坂东的下冢屋寺和北海道的大斋府等地，但本文在长屋亲王对各省政策的背景下重新评估了他的早期统治。这篇文章论述了三点。首先，根据对塔加府和大宰府二世建立日期的分析，建议它们都是在约罗四世的羽户和临诗起义之后作为省控制新政策的一部分而建立的。这里也有一些关于其他主要政府部门组成的讨论。其次，考察了日本三大戒律寺之一的下冢屋寺与官办寺院并列的时期，确认了当时认真考虑了田谷町废寺、筑城观藏寺等官办地方寺院的设立政策和寺院合并的宗族寺院政策。第三，虽然这些行省政策以及佛教寺庙和其他设施的建立直接开始于与hayto和Emishi战争相关的边境政策，但它们不是简单的边境政策，而是可以被视为国家防御王国措施的一部分。长屋亲王的这些政策延续了藤原二世的政策，但在长屋亲王的领导下，省政府的实质性进步和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.
