摘要：In the present paper we analyzed factors of the social background responsible for the rise and decline of dressmaking schools, which played a major role in the westernization of clothes in postwar Japan. Our analysis was based on statistical data arranged in chronological order, from which we obtained new knowledge and insight. In connection with the rise of these schools, we clarified the influence of various factors on the dressmaking boom. These factors were: (a) the supply-demand structure such as the production volume of the textile industry and the household spending situation; (b) the popularization of fashion; and (c) various mass media. In connection with the decline of dressmaking schools, we also clarified the influence of various factors on the boom convergence. These factors were: (a) the commercialization of synthetic fibers and automation of the manufacturing process; (b) the rise of the apparel industry by mass production and development of distribution sales channels; (c) the spread of ready-to-wear through marketing; and (d) the increase of students receiving higher education.
