In recent years Maeda Tsutomu(前田勉) emphasized the importance of 兵學 in Japanese thought history and argued that 兵學 rationalized Bui(武威) and became a philosophical basis for forming concept of Japanese confucianist’s idea of garrison state(武國觀念). However, will not conflict between the identity of confucianist that intends peace inside the civilized area and the idea of garrison state? In the case of Ito Togai(伊藤東涯), he is escape with a race-oriented, geographical Huaikuan(華夷觀), and he think that depending on the presence or absence of civilization, China may become “夷”, and Japan may also become “和”. However, this 華夷觀 shows a crack in case of Korea. In the preface attached to the 三韓紀略, 東涯 shows the country-centered recognition that ancient Korean Peninsula was subject to Japan. A sense of superior consciousness is seen. However, on the other hand, criticized the people of both countries have fallen into the disaster by the abuse of military force on the Japanese invasion of Korea in 1592. And he insist that Japan will be reborn as a Confucian nation.東涯‘s civilization directivity appears more clearly when compared with Ogyu Sorai(荻生徂徠). Confucianism in Tokugwa Japan seems to have advanced walking up and down between 武威 and civilization(文明) up to the modern era. Confucian civilization is balanced so that 武威 do not run away. However, in the face of the Western invasion, the equilibrium cone tilted suddenly towards 武威. Japan's thought history research has been structured to emphasize Japanese independence and individuality. However, when consider existence of Korea, it turns out that the aspect of pre-sino-centrism in modern Japan does not necessarily bring positive outcome.
