答志島寝屋慣行の維持と変容:社会生態学的視点に基づくエスノグラフィー<sup>1）</sup> The maintenance and change of the "<i>Neya</i>" custom on Toshi Island: Ethnographic research from a socio-ecological perspective
This micro-ethnographic research focuses on a traditional custom on Toshi Island, in Japan. When first-born sons on the island graduate from junior high school, they form a small group of <i>neya-ko</i> (quasi-brothers) and sleep over at the house of their <i>neya-oya</i> (quasi-parents) every night until they reach the age of 26. They maintain the quasi-family relationship and help each other all their lives. Why does the <i>neya</i> custom still continue on this island, while most similar customs have already disappeared in other parts of Japan? To answer this question, we conducted participant observations and unstructured interviews. The results suggest that the ecological environment of the island has exerted an important influence on the <i>neya</i> custom. In spite of recent drastic social and economic changes in the islanders' lives, the <i>neya</i> custom still plays a key role in building sustainability in the community. Based on these findings, we discuss how the multi-layered environments of the island interact with this specific custom that has been fostered through the years.
