The political relationship between the ROC on Taiwan and Japan is not progressive enough after the end of their diplomatic ties in 1972. However, with the collapse of the Soviet Union in 1991, the rise of the PRC and the adjustment of US world strategy after the “911 tragedy,” the focus of Taiwan-Japan relations has changed from economy to security cooperation over the past ten years. On the other hand, the restart of the Japanese coalition government in 1993 not only meant the end of the LDP’s one-party system, but also implied that most Japanese have a common will to “Farewell to the defeated status and pursue the Normal State.” This change reflects that Japan will not only continue following US world strategy, but will also play a more active role in the west pacific zone from now on. With such a trend, the author suggests that both Japanese and Taiwanese leaders should understand each other more and cooperate to devote themselves to create a persistent peace and development in the East Asia.
