Even though Taiwan is similar to Korea in many aspects, Koreans are not usually keen on Taiwan and their understanding of it is at a low level. Is it because Taiwan is a small country, far away from Korea geographically and historically, and thus can't be reached by the interest of Korean people who struggle to survive between big countries around them? Or is it because of "Orientalism within ourselves", that is, a misrecognition caused by a prejudice or the following arrogance toward Taiwan? If so, where can we find the origin of this misrecognition? On the basis of these issues, this study aims to trace back how and to what extent the Korean people of the Japanese colonization understood Taiwan and on what ground the understanding became possible, by researching the related articles of The Chosun Ilbo, one of the leading newspapers at the time. Research methods include the analysis of the statistics for the number of articles in terms of publishing year, topic, and feature to find motivations and reasons for Korean people's interests in Taiwan, and the analysis of the content of articles to pin down their understandings and attitudes toward Taiwan. According to the annual statistics for the number of articles, many articles about Taiwan were published in the years that had the news such as the bankruptcy of Taiwan Bank (1927), the execution of rice control policy (1933, 34), the great earthquake(1935), and the Wu Shi Affair(1930). As for the topic, the nubmer of the articles about economy and politics amounted to 79% of all. Most of the articles were featured as the simple report about various events, while the editorials or columns were rare. In the politics section, the number of articles about the nationalist movement amounted only to 30%, which mostly covered the leftist movement rather than the self-governing issues, and the rest were about colonial politics and policies. In the economy section, most articles dealt with the bankruptcy of Taiwan Bank, the rice control policy, and the Taiwan rice. In the society section, the articles about earthquakes and cyclones were dominant. And in the culture section, more than half of the articles dealt with traveling and customs, especially those of High Mountain Tribe. Taiwan, meanwhile, was understood as a hot southern island of evergreen beauty and wealth due to bountiful natural resources, but as a land of strangers which had no intimate relationship with Korea due to its geographical distance. It was also recognized as a land of barbarians who were supposed to cut the human head cruelly. On the other hand, Taiwan was recognized as a land that could compete with Korea for its rice production or that could supply their rice for Korea in an urgent situation. In fact, Korean people supposed that Taiwan maintained a culture of low quality and it had the problems with its nationalist spirit and identity, even though it shared the similar experience with Korea as a Japanese colony. And thus, Korean people seemingly considered Taiwan as an irrelevant country. The newspaper articles about Taiwan mostly tended to deal with its politics and economy rather than its society and culture which were the necessary areas for the unbiased understanding of Taiwan. They also tended to deal with the simple reports on the colonial governing system, and the articles about the nationalist movement to protest against the colonization were relatively in small numbers. The reasons for this tendency were that (1) no freedom of speech was allowed by the suppression of the colonial government in Korea, and (2) the colonized Korea seemed to show a sense of superiority to Taiwan in spite of the sympathetic relationship to each other as the same Japanese colony.
