The Asia-Pacific War in 1941 is also a war which Koreans suffered in modern times and caused a tremendous change to the topology of Korea at that time. The Greater East Asia War and the Korean Peninsula published in 1942 is an important book which discussed the topology of Colony Joseon in connection with this war shortly after the Asia-Pacific War broke out. The authors of this book were ideologues representative of ‘national literature’ during the latter part of Colony Joseon Era, who were Japanese intellectuals residing in Joseon and intellectuals from Colony Joseon. They understood the reshuffle of East Asia’s regional order caused by the Asia-Pacific War from the perspective of Colony Joseon on the one hand, and attempted to reestablish the topology of Colony Joseon in the reshuffling process of East Asia’s regional order on the other hand. At that moment, Colony Joseon’s topology was transformed from logistics base for advance into the Continent after the Second Sino-Japanese War into logistics base for building ‘the Greater East Asia Co-Prosperity Sphere’.
