The temination of an existing order, as a matter of course, is accompanied with the change of criteria values. So it is natural that since defeat, Japan, having been forced to stay in an American-centered intemational order, began agonizing seriously in connection with its own identity under the new world order referred to as post-cold war. But, at the same time, we must pay attention to the fact that questions conceming what Japan is to be like have been raised frequently throughout the process of its modem state fomation since the mid-19th century in the Japanese archipelago. That granted, what was the process like? It is hardly possible to rnderstand modem Japan"s agony relating to its identity without considering the argument about Nihon Kokutai. The perception of the “other” in Japan"s modern history was well brought out in its view of Westem civilization and its outlook on Asia, while that of the self-consciousness was expressed in the argument conceming Kokutai. This is to analyze the interaction between the intemal and extemal crisis arising from the transitional situation in Japan and the subjective crisis-consciousness, focusing on the process of the unfolding of Kokutai discourse.
