Social Mobility and Network of migrant in Setouchi Region in Japan

这项研究来自于对田岛（广岛县）的村庄社会的扩展调查，田岛是位于日本西部本州和四国之间的濑户内海的许多小岛之一。它考察了自第二次世界大战结束以来那里发生的社会变化。研究分析了小村的产业、就业结构和生活方式之间的关系，既关注了留在岛上的人，也关注了选择离开的人。自第二次世界大战结束以来，许多岛民往返于田岛和外部世界之间，在南极捕鲸、濑户内海航道(例如。（连接九州和大阪地区的煤炭船）、造船和其他与海洋有关的产业。因此，对于这些岛民来说，旅行是工作和生活中不可或缺的一部分。岛上的每个社会阶层都有自己独特的网络，影响着其成员的工作机会和选择。岛上有几个小村庄，从江户时代到第二次世界大战，每个小村庄都有自己的发展道路。由此产生的每个村庄积累的资源差异继续影响着战后时期的就业结构。我的研究考察了二战后Machi村的变化，通过其工业，就业结构和生活方式揭示，利用微观层面的观点，考虑到村庄的个人情况，以及宏观层面的观点，涵盖移民和延伸到岛屿以外的职业趋势。研究对象来自航海文化，并习惯于乘船旅行。因此，这项研究针对的是流浪是一种生活方式的人，而不像之前关于日本战后移民的大多数研究，它们关注的是农民，在农村或城市地区固定定居被视为常态。因此，我的工作为重新思考适用于现当代日本的移民和定居概念提供了新的理论框架的种子。少

This study comes out of an extended survey of the hamlet society on the Tajima island(Hiroshima prefecture), one of many islets in the Seto Inland Sea lying between Honshu and Shikoku in western Japan. It examines the social changes that took place there since the end of World War II. The study analyzes the relationships between the hamlet's industries, employment structure, and living practices, paying attention to both people who remained on the island as well as those who chose to leave. Since the end of World War II, many islanders have gone back and forth between the island of Tajima and the outside world, working in Antarctic whaling, Seto Inland Sea shipping lanes(e.g., coal ships connecting Kyushu and the Osaka area), shipbuilding, and other sea-related industries. For these islanders, travel is thus an integral part of work and life. Each social stratum on the island has its own distinct network that affects the job opportunities and choices of its members. The island is home … More to several hamlets, each of which pursued separate developmental paths from the Edo period until World War II. The resulting differences in resources accumulated by each hamlet continued to influence employment structures in the postwar era. My research examines post-World War II changes in the village of Machi as revealed through its industry, employment structure, and ways of life, utilizing both micro-level perspectives taking into account the individual circumstances of the hamlet as well as macro-level perspectives covering emigration and occupational trends extending beyond the island.The subjects of the study come from a seafaring culture and are accustomed to traveling aboard ships. The research accordingly deals with people for whom wandering is a way of life, unlike most of previous works on postwar migration in Japan, which focus on farmers and where fixed settlement either in the home village or in urban areas is regarded as the norm. My work thus offers the seeds of a new theoretical framework for rethinking the concepts of migration and settlement as they apply to modern and contemporary Japan. Less
