戰前獻身於中國留日學生及中國京師法政學堂日語教育之松本龜次郎，以1903至1945年教授最多中國人聞名，既使戰後歷經65年仍為他舉辦紀念儀式。另一方面，蔡茂豐為努力引導戰後台灣人日語教育並不辭辛勞於斯之代表台灣的日語教育家。 筆者嚐試從日語教育史観、教育観、教材観、教授法観等観点比較兩者超越時空的共同點，以提出對中國人日語教育者具備的特徵。 本論文為上述研究之一環，首先聚焦於兩個不同時代背景中從事日語教育者的成長過程，從理解身為日語教育者的形象開始，提出兩者間所觀察到的12個共同項目。

Kamejiro Matsumoto who dedicated his life in teaching Japanese language to Chinese students in Japan and China before the war is known that he taught Japanese to the largest number of Chinese students from 1903 to1945, and his commemorative events are held even now 65 years after his death. On the other hand, Tsai Mao-Feng is a Japanese language educator representing Taiwan, who has led Japanese language education in the post-war Taiwan and has put his all efforts to diffuse Japanese language. The author compared these two educators in the light of Japanese language education history, educational philosophy, perspectives for materials and teaching methods and tried to find the characteristics as Japanese language educators to Chinese people by searching and describing the similarities that they share beyond time and space. In this paper, 12 similar characteristics that they share in their paths in the Japanese language education and in two different historical backgrounds are discussed.
