This study examines the representation of Korea and Manchuria in Kanbun Taiwan Nichinichi Shinpō(1905-1911), a colonial-era newspaper in Taiwan. The findings reveal that the newspaper consistently depicted Korea as politically unstable, with resistance movements labeled as “riots” or “bandit activities.” Such portrayals justified Japan’s intervention and annexation while reinforcing its role in modernizing Taiwan. After annexation, the focus shifted to Korea’s economic potential, such detailed reports as on Taiwanese salt sales in Korea reflected specific Taiwanese interests. Manchuria was framed as an economically valuable and strategically important region, aligning with Japan’s ambitions for continental expansion and spatial reorganization in Northeast Asia. Reports on mounted bandits and plague were not neutral but aimed at shaping Taiwanese perceptions to support Japan’s imperial goals, reinforcing the necessity of its presence in both Manchuria and Taiwan. Whether highlighting Korea’s instability or economic value, or Manchuria’s opportunities and threats, the newspaper legitimized Japan’s colonial rule and cultivated support among Taiwan’s educated elite. These findings underscore the role of colonial media in shaping public opinion and justifying imperial expansion.
