Since the 1980s, Japanese scholars have been doing field research on ethnic minorities in China. Along with its rich and colorful national culture as well as its ecological culture, Guangxi has piqued the interest of Japanese scholars. In order to provide a multi-dimensional observation perspective and useful reference for the sustainable development of contemporary ethnic minorities in Guangxi, this paper analyses and discusses the research methods, discipline fields, and academic contributions of Japanese research on ethnic minorities in Guangxi over the last 40 years.
