End of War Commemoration Day

What Is End of War Commemoration Day?

Every August 15th is "End of War Commemoration Day" (終戦記念日, Shūsen Kinenbi) — officially "the Day for Mourning of War Dead and Praying for Peace" (戦没者を追悼し平和を祈念する日). On August 15, 1945, at noon, Emperor Hirohito's recorded voice was broadcast on radio for the first time — the "Gyokuon Hōsō" (玉音放送, "Jewel Voice Broadcast") — announcing Japan's acceptance of the Potsdam Declaration and the end of World War II. For millions of Japanese who had never heard their emperor speak, and who had been told that Japan was winning the war, the broadcast was a moment of shattering disorientation and grief.

The Gyokuon Hōsō: Japan's Surrender

The Emperor's announcement, delivered in formal classical Japanese that many listeners could barely understand, spoke of "a new and most cruel bomb" (Hiroshima and Nagasaki), the "general trends of the world," and the need to "endure the unendurable and suffer what is insufferable." The broadcast was intentionally indirect — the word "surrender" was never spoken — but its meaning was unmistakable. Across Japan, soldiers laid down their weapons, civilians wept in the streets, and a country that had been mobilized for total war confronted the reality of defeat.

The National Memorial Ceremony

Every August 15th, the government holds the "National Memorial Ceremony for War Dead" (全国戦没者追悼式) at Budokan in Tokyo, attended by the Emperor and Empress, the Prime Minister, members of the Diet, and representatives of bereaved families. At noon, a moment of silence is observed across the country. The Emperor reads a statement reflecting on the war's devastation and renewing Japan's commitment to peace. The ceremony is broadcast live on national television.

August 15th in Japanese Memory

For many Japanese of the wartime generation, August 15th remains the pivot point of their lives — the day that divided everything into "before" and "after." The war killed approximately 3.1 million Japanese military personnel and 800,000 civilians; millions more were wounded, traumatized, or dispossessed. The postwar peace constitution's Article 9 — renouncing war as a sovereign right — was adopted in 1947 as a direct response to the catastrophe that culminated on August 15, 1945.
