A study on methodology of architectural drawings in Edo-era

向大约2800个组织发出问卷，询问他们是否拥有萨水--绘画让我们确定大约40个组织是萨水大量收藏品的所有者。在研究中，我们选取了约800幅图画进行调查，并从所选的800幅图画中的约500幅图画中获取了书目数据和照片。在研究中，我们获得了以下结果：1.大部分萨水图画由地方政府的图书馆、教育机构和社区中心保存，目前保存的萨水图画的数量与各自氏族内原有文献的总数成正比，在较大的宗族中存留概率较高。本研究的负责人后藤在《中井家族绘画方法论研究》(后藤，《中井家族文献研究，第一卷至第十卷，1976-1985)》中指出的事实也适用于其他家族的绘画方法。在一些宗族中也存在着独具特色的绘画。例如，中井家族的绘画类型在18世纪下半叶从Hariezu-Drawing(用不同颜色的纸粘贴在白色背景纸上说明的平面图)转变为Kakiezu-Drawing(用毛笔或类似工具直接在白色背景上绘制的平面图)。然而，在九州地区的竹尾-长岛和岛原-松原部落，整个江户时代都只使用Hariezu类型。其他独特的技术也在冈山-池田和广崎-津格鲁部落得到了发展。

Questionnaires sent to around 2,800 of organizations to ask if they own Sashizu-drawings allowed us to identify around 40 organizations as owners of large collection of Sashizu. From the collections we selected approximately 800 drawings to investigate, and bibliographic data and photographs were taken from approximately 500 drawings out of the 800 drawings selected.In the study we obtained the following results :1. Most Sashizu-drawings are preserved by the libraries, educational institutions and community centers of local governments, and the number of Sashizu-drawings currently preserved is proportional to the total number of documents that originally existed within the respective clan with higher remaining probability in larger clan.2. The facts pointed out by Goto, chief of this study, in his study on Nakai Family's drawing methodology (Goto, "A study on Nakai Family's documents, Vol. 1 through 10", Chuohkoronbizyutsusyuppan, 1976-1985) are also applicable to these in other clans.3. Drawings with unique features also existed in some clans. For examples, Nakai Family's drawings changed their type from Hariezu-drawing (a floor plan illustrated by using different colored papers pasted on white background paper) to Kakiezu-drawing (a floor plan drawn directly on white background by using brush or the like) in the later half of 18 century. However, in the both Takeo-Nabeshima and Shimabara-Matsudaira Clans in Kyusyu area, only Hariezu type is used throughout Edo era. Other unique techniques were developed in Okayama-Ikeda and Hirosaki-Tsugaru Clans as well.
