The National Memorial Service for War Dead (全国戦没者追悼式, Zenkoku Senbotsusha Tsuitōshiki') is an official, secular ceremony conducted annually on August 15 by the Japanese government at the Nippon Budokan in Tokyo, Japan.

[citation needed] By decision of the Third Yoshida Cabinet (Prime Minister Shigeru Yoshida), on 2 May 1952 the Emperor Shōwa and Empress Kōjun of Japan held a memorial service for war dead in Shinjuku Gyoen.

In 1963 the date was moved to August 15, the day the Hirohito surrender broadcast (玉音放送, Gyokuon-hōsō) had aired in 1945.

The Emperor and Empress are always in attendance, as well as representatives of business, labor, political, and religious organisations, and bereaved families.

No invited leader has ever absented himself from the memorial, including those who have criticized visits to Yasukuni Shrine.
