Specifically, I look at how the particular social-geograph- ical conditions of different communities create diverse conceptions of such boundaries, including the presence or absence of the boundaries, within the same region. Here, I focus on three Japanese villages encompassing seven local religious communities of Shinto-Buddhists, Catholics, and former Hidden Christians on Hirado Island in Kyushu. These villages are viewed respectively as examples of contrastive coexistence, degeneration, and expansion in territoriality. Among the seven religious communities, only those believing in Shinto-Buddhism, as well as Hid- den Christianity, have maintained their folk boundaries. These communities satisfy the conditions of an agglomer- ated settlement form, a size generally larger than ten households, a location isolated from other communities within the village, and strong social integration. In contrast, Catholics have not constructed such boundaries based on their historical process of settlement. However, they have influenced the forms of Shinto-Buddhists’ territoriality, although not those of Hidden Christians.
