On the 70th anniversary of Japan’s surrender ending WWII，Japan strengthens the historical revisionism in its overseas publicity，attempting to get Japan’s political demand of changing the post-war regime understood and accepted by the international community. Japan tries every effort to invite foreign leaders and people to visit atomic bombing sites in Hiroshima and Nagasaki，seeking for sympathy and support for Japan as a victim of atomic bombing and highlighting Japanese pacifism and “international contribution”. Japan also takes advantage of applying for the World Cultural Heritage and Memory of the World and persuades UNESCO in reforming its application system，in order to create a favorable international public opinion and downplay Japanese history of colonial rule and aggression. The Abe statement marking the 70th anniversary since the end of WWII on August 14th，2015 can be regarded as an international declaration relating to its attempt for changing the post-war regime. Japan’s public diplomacy above has not helped the historical reconciliation between Japan and other Asian countries such as China and Korea. On the contrary，the historical issues have weakened the effect of Japan’s public diplomacy in softening critiques from the international community.
