Ginseng had not been produced at the early Edo Era in Japan.With the popularity of Chinese traditional medicine in Japan and the expansion of consumer demand for ginseng,the country began to introduce ginseng cultivation from China and North Korea,trying to realize the localization of ginseng.Later,with the implementation of the Shogunate's incentive policy for ginseng planting,Japan's ginseng planting area continued to expand.The development of ginseng cultivation in the country in modern times is not only a history of the prosperity of Japanese traditional herbology,but also a witness of the flour-ishing exchanges of medicine material and culture represented by ginseng in East Asia.This paper takes the cultivation of ginseng in modern Japan as the research object,and investigates the interaction between the development of ginseng cultivation in Japan and Chinese medicine and the market behind the ginseng trade between China and Japan,hoping to restore that period of history of medical cultural exchange in East Asia.
