The 1900 Boxer War Medal was a Japanese medal created by Imperial Edict No. 142 and issued on April 21, 1901. It’s a commemorative medal for those who had participated in the relief of the Beijing legations during the Boxer Rebellion.
The Military Medal of Honor (or 従軍記章 jugun kisho in Japanese) was a military decoration for meritorious service to the Empire of Japan, formerly awarded to all military personnel who participated in battles in a war and effectively abolished during the Allied Occupation of Japan in the post-war years (1945–1951).
The plausible re-institution of a modern equivalent was made unlikely by the adoption of Japan’s post-war Constitution which disavows the right of the state to engage in aggressive war.
