The aim of this paper is to clarify the maintenance mechanism for the fishing village landscape-which was the subject of conservation in the Sakitsu District, Amakusa City, Kumamoto Prefecture-by analyzing the effects of changing livelihoods and activities on the preservation of the landscape. Since 2006, activities related to landscape conservation have been carried out in the study area, with the aim of registering the area as a world heritage site. The landscape of the fishing village, represented by "Kake (like a pier) and Toya (like a alley)," was selected as one of the cultural landscapes of Japan. Various actors-such as the local government, residents, and some academic expert-became involved in these efforts. The main form of the fishery was characterized by the process of pearl aquaculture and drag net fishing until the early 1960s, during which time the use of engine-powered small fishing boats increased, even as non-powered fishing boats were still in existence. Repair work was needed, because the material needed for fishing gear was derived from the natural environment in the fishery. Therefore, Kake had an important role for both some land works and for the moorings some boats. Trawl-net fishing became the main fishing method in the mid-1960s. Since the fishing boat used with trawl nets is larger than that used in drag net fishing, it has become difficult to moor fishing boats by the Kake. Fishing is no longer a necessary economic activity for the Kake. However, in the 1970s, construction also began on the new Kake, which was constructed for non-economic motives. The number of boats with outboard engines, as well as non-powered fishing boats, such as those with moorings, did not decrease until almost the end of the 1990s. Thus, the boat moorings served several purposes, including that of holding the boat, as well as of leisure. A Kake that has been maintained for these reasons is recognized as specific to its local, and is the subject of conservation.
