Abstract
Chapter 1: The purpose of this study is to clarify the formation factors of "Naga-hisashi" found in Okura of Okura-syo owned by Kaga domain in the Edo Period. The eaves of Okura could be classified into the following two categories. The first one is "Naga-hisashi", which covers around the entrance, the second one is "Tomae-hisashi", which covers only the entrance.
Chapter 2: The previous studies and the procedure of this study were shown.
Chapter 3: I examined commonality and forming factors of "Naga-hisashi" of the Okura-syo owned by Kaga domain. First, I examined the use and scale of buildings with "Naga-hisashi". In the type of Okura-syo in which "Naga-hisashi" are common, "Naga-hisashi" tend to be set up at inspection station and the largest Okura.As these buildings play a central role in carrying a tax rice into the Okura-syo and carrying out the tax rice from the Okura-syo, this result was natural. Secondly, the layout of "Naga-hisashi" in Okura-syo was examined separately for each type of building arrangement. It was thought that the "Naga-hisashi" was forming the main circulation of people and goods. This is because the "Naga-hisashi" connect the garden behind the gates and the back of the site at the Okura-syo of the L type, enclosure type, parallel B type, garden detached type. On the other hand, in Okura-syo where is difficult to provide a main circulation such as parallelAtype and parallel C type, could not be seen "Naga-hisashi".
Chapter 4: In order to verify the formation factors of the "Naga-hisashi"clarified in the previous chapter, I compare the Okura-syo owned by Kaga domain and the Okura-syo owned by Tottori domain that was accounted by "Naga-hisashi". I picked up the Okura-syo owned by Tottori domain which have many "Naga-hisashi" and compared it with the Okura-syo owned by Kaga domain. In Okura-syo owned by the Tottori domain the "Naga-hisashi" connected the front gates and the back gates, the front gates and the back of the site, like the Okura-syo owned by Kaga domain.
Chapter 5: In conclusion, In this study, I found that "Naga-hisashi" in the Okura-syo owned by the Kaga domain that is the region with many rainy days, functioned as a passageway connecting the entrance of Okura-syo and the back of the site. In other words, it was concluded that the "Naga-hisashi" formed the main circulation of the Okura-syo.
