Ji Kang, an Anhui-born scholar, has a wide influence in the world, especially in Japan, which is separated from China by a strip of water.
However, although Ji Kang has a far-reaching influence in Japan, there is a lack of research on his tolerance. As a part of the study on Ji Kang's reception in Japan, this paper sorts out and analyzes the research on Ji Kang in Japan, and draws the following conclusions: Japan's academic research on Ji Kang can be traced back to the 1950s, starting with two scholars, Shimizu Kiyosi and Hayasida Sinnosuke; In 1960s and 1970s, represented by Kouzen Hirosi, new research methods began to sprout, and ideological and cultural research was further developed; In the 1980s and 1990s, there was a great breakthrough in the number and scope of researchers, which not only realized the innovation of poetry research methods, but also opened up the research field of Ji Kang's music theory and health preservation. In the 21st century, while the number of researchers is further increasing, Ji Kang's research in various fields is constantly developing and prospering, especially in the field of theoretical research, which not only criticizes the old theory, but also establishes a link between Ji Kang's thought and hermit research.
