ABSTRACT

The assertion of Japan’s dominance over the southern part of the Korean Peninsula in ancient time, represented by Japanese Ministry of Imna, has been mentioned as a representative example of historical distortion and arbitrary interpretation of historical records for the beautification of invasion. Indeed, to Japanese historians at the time, the assertion of Japan’s dominance over the southern part of Korea was close to belief, and they confirmed it as a historical fact in some way. Then, did all Japanese historians in the past make the same argument about the Japan’s dominance over the of Korea? This article answers this question through Hiroshi Ikeuchi’s writing, A Study on Japanese Ancient History, published in 1947. As the title indicates, Ikeuchi considered Japan’s dominance over the Korea in connection with the debate about Yamatai’s location in Japanese academia since the 20th century. This is because the location of Yamatai, where the Wei’s envoy came from in the 3rd century, was an important key to determining the timing of the emergence of a unified state that dominated Nara to Kyushu in Japan, which is the premise of the Yamato government’s dominance over the southern part of Korea. However, the same was true of major Japanese historians who studied Korean ancient history before 1945. During the colonial period, Japanese historians have showed a difference of more than 150 years from the time when the Yamato government’s dominance over the southern part of Korea began, and this difference was caused by the fact that they had different thought about the Yamatai’s location. In the first half of the 20th century, the claim that Japan dominated southern Korea and the Yamatai debate that took place in the course of Japanese history’s explanation of the emergence of a unified power in ancient Japan were related suggests that the historiography of colonialism was not only a ruling ideology but also a characteristic of the modern historiography.
