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，本文对多贺城、多贺城废寺、下冢药师寺、大泽府、筑志观圆寺以及周围的寺庙、政府和省政府以及平条宫的建造和修复进行了年表。以往的研究都是分别考察东北的多贺城、坂东的下冢药师寺、西海道的大泽府等地，但本文以长谷亲王的行省政策为背景，对长谷亲王的早期统治进行了重新评价。首先，通过对多贺城和大泽府二的建立时间的分析，可以认为这两个地方都是在代罗4年隼人、子起义后，作为新的地方统制政策的一部分而建立的。这里也有一些关于其他主要政府办公室的组建的讨论。其次，考察了日本三大戒寺之一的下冢药师寺与官寺并列的时期，确认了当时对多贺城废寺、筑志观圆寺等官立地方寺庙的政策以及寺庙合并的宗庙政策的认真考虑。第三，虽然这些地方政策以及建立佛寺和其他设施直接起源于隼人和赤子战争的边境政策，但它们不仅仅是边境政策，而是可以被视为国家防御措施的一部分。长屋亲王的这些政策是藤原不仁政策的延续，但在长屋亲王领导下，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.
