Nippon Post Conclusion of WWII Peace Treaty

NIPPON POST on 9 September 1951 issued a First Day Cover commemorating the Conclusion of the WWII Peace Treaty. A variety of stamps appeared on the covers, usually a red  pheasant with a face value of 59¥ and  chrysanthemum (imperial symbol of Japan) with a face value of 24¥. The red pheasant stamp was an air mail issue. The chrysanthemum stamp was printed in two colours: blue and brown. Some covers included a stamp  depicting the flag of Japan. The cachet almost always featured the flag of Japan set within a wreath of chrysanthemums.  In Japan, the  yellow flower symbolises the sun and the light (immortality).

The Treaty of San Francisco  (San-Furanshisuko kōwa-Jōyaku), also called the Treaty of Peace with Japan (Nihon-koku to no Heiwa-Jōyaku), re-established peaceful relations between Japan and the Allied Powers on behalf of the United Nations by ending the legal state of war, military occupation and providing for redress for hostile actions up to and including World War II. It was signed by 49 nations on 8 September 1951, in San Francisco, California, at the War Memorial Opera House.

The treaty came into force on 28 April 1952. It ended Japan's role as an imperial power, allocated compensation to Allied nations and former prisoners of war who had suffered Japanese war crimes during World War II, ended the Allied post-war occupation of Japan, and returned full sovereignty to it. This treaty relied heavily on the Charter of the United Nations[4] and the Universal Declaration of Human Rights[5] to enunciate the Allies' goals. In Article 11, Japan accepted the judgments of the International Military Tribunal for the Far East and of other Allied War Crimes Courts imposed on Japan both within and outside Japan.
