This paper explores the nationalism in Japanese films of 20th century. Actor Yosuke Kubotsuka has appeared on "Go", "Madness in Bloom", and "I Go Die Only for You", and these films show such trend. On "Go", he acts 'Sugihara' who feels national identity conflict between Korea, North Korea, and Japan. After this film, he shows nationalistic behaviors, and he plays the role of right-wing gangs who wants to 'clean' Shibuya on "Madness in Bloom". On "I Go Die Only for You", he acts the role of Kamikaze Tokkotai(suicide commando band) who gladly wants to go die for keeping 'something very valuable', that is the family and the nation. It is very difficult to consider such trends of nationalism of young generation of Japan as the uprising of political nationalism, or the ideological cynicism like seen '2 channel'. But it is more important to recognize two ways of representation of nationalism on the popular culture of Japan, and to discuss how to overcome the exclusive nationalism and to recover the value of 'publicity' of Japanese society.
