Economic globalization has led to the rapid worldwide increase of the mobility of international labor forces and migration to developed countries, including in Japan. Since the 1970s, Japan has been faced with an aging population and decreasing birthrate, accompanied by a severe shortage of workers in both metropolitan and rural areas. Thus, from the 1980s, Japan has allowed immigrants to enter the country to help resolve the workforce shortage. The majority of resident foreigners working Hiroshima Prefecture live in Hiroshima. In this study, we sought to determine their characteristics (e.g., nationality, employment situation and address). We also analyzed the life courses of female foreign workers in Hiroshima by interviews and questionnaires to clarify their personal characteristics and position in the Japanese labor market.
