Is Madame Chen, written by writer Shoji Soichi of the Japanese colonial period, a book that look at “Mainland (Japan)-Taiwan Marriage” in a light-hearted way? Or, is it a realistic portrait of the cultural identification that flows between the native land and the foreign country? In the field of Taiwan Literature, what meaning can this work bring to us since its Japanese author possessed advantages such as cultural power, national resources, and media? In this article, we try to discuss the core of the problem of Madame Chen through the text. Did Shoji Soichi, through Madame Chen, delve into the suggestion that the concept that sustains Japan’s existence is actually the purity of race? Owing to “The Great East Asian War”, the policy of “The Combination of Midland Japan and Taiwan” must be implemented. Japan discarded the theory of pure race, transforming the name of “lineage” to that of “love”, in order to increase the number of Kominka for the need of soldiers for the sacred war. In this work, Soichi, in an undertone, accused the war while facing the questioning of the dispersal of the Japanese race. In this study, in addition to the deep belief in the lineage of his country, Soichi was also proud of the Japanese culture that he possessed. He hand to erase, rename, and re-remember the reasonability of the long existing value on Japanese lineage. It turns out that the existence of a nation or history can be collaged, folded, forgotten, and re-started. Through Madame Chen, we see how Shoji Soichi utilized literary works to express his opinion on war.
