The purpose of the study is to identify the actual condition of the stone walls called Shishigaki (wild boar defense walls) by investigating the current state and examining the reasons of demolishment. By interpretation of historical documents, interview and on-site measurement surveys were conducted at nine districts located at the foot of Mt. Hira. As a result, it was confirmed that Shishigaki was built in all of the nine districts from the late half of 1700 to 1800 with the permission of the government. It is confirmed that about 4.7 km of Shishigaki relics remain at altitudes of 100 m to 230 m; Shishigaki is found either linear or surrounding types, and the building techniques vary with the locations. The study identified out that not only the residential and road development but some of economic and social activities were the reason of demolishing the Shishigaki relics.
