In recent years，Japan，taking advantage of the 70th anniversary of the UN and the 60th anniversary of Japan’s joining the UN，has worked actively in the PR for the permanent membership of UN Security Council. Since Japanese Prime Minister Shinzo Abe took office for the second time，Japan has integrated its diplomatic PR for becoming a permanent member of the UN security council with its national strategic diplomacy，attempting vigorously to draw support from relevant countries and seeking for more diplomatic resources and space for its international communication. Japanese government puts more emphasis on rebuilding its national image as the defeated country and victim in the atom bombing in WWII，as well as a country of contribution and responsibility in post-war era through various means of diplomatic PR.
