Taiwanese writers during the Japanese occupation period did not often depict Japanese Imperial Emperor and family since they were more concerned with colonial policy in colonial Taiwan than imperial power that only symbolized the national body for the colony. But in A Railway Runningthrough Taiwan, anovelbythe Japanesewriter Nisikawa Mituru, who had long stayed in Taiwan, he represents the majesty of Imperial Household and reconfigures the history of Japanese living in Taiwan through the lens of a photographer character and the style of reportage. Through closely analyzing the text, this paper attempts to articulate how Japanese writers in Taiwan represent Japanese Imperial Household in the process of colonial modernization and the meanings of these representations as well as the double consciousness of homeland within these Japanese writers’ identities throughout the history of colonial Taiwan and Japanese imperialism.
