VJ Day, which stands for Victory over Japan Day, marks the day Imperial Japan surrendered in World War II, effectively ending the deadliest conflict in human history. While Victory in Europe (VE Day) had been declared in May 1945, intense fighting continued in the Pacific theater for nearly three more months.
Key Dates of VJ Day
The commemoration of VJ Day occurs on two main dates, largely due to geographical time zones and the distinction between the announcement of surrender and the formal signing of the documents:
August 15, 1945: This date is recognized by the United Kingdom, Australia (where it is known as VP Day for "Victory in the Pacific"), and many other Allied nations. It marks the day that Japanese Emperor Hirohito announced the unconditional surrender to the Japanese people via a radio broadcast. Upon hearing the news, celebrations erupted across the world.
September 2, 1945: The United States officially commemorates VJ Day on this date. It is when the formal surrender ceremony took place aboard the USS Missouri in Tokyo Bay. Dignitaries, including General Douglas MacArthur for the Allied powers, and representatives from Japan, signed the Japanese Instrument of Surrender, officially concluding World War II.
The Path to Surrender
The end of the war in the Pacific was precipitated by a series of momentous events in August 1945:
Potsdam Declaration: On July 26, 1945, Allied leaders issued the Potsdam Declaration, which demanded Japan's unconditional surrender and warned of "prompt and utter destruction" if it refused.
Atomic Bombings: After Japan ignored the ultimatum, the United States dropped atomic bombs on two Japanese cities. The first was on Hiroshima on August 6, and the second was on Nagasaki on August 9. These bombings caused unprecedented destruction and loss of life.
Soviet Invasion of Manchuria: On August 9, the same day as the Nagasaki bombing, the Soviet Union, which had previously been neutral in the Pacific War, declared war on Japan and launched a swift and massive invasion of Japanese-controlled Manchuria.
Faced with these devastating events and the inevitability of defeat, Emperor Hirohito intervened and announced Japan's intention to surrender on August 15.
Commemorations and Significance
VJ Day is a day of both celebration and somber remembrance. In 1945, the news was met with immense relief and joy, with massive street parties and parades in Allied countries.
Today, VJ Day is observed with various events:
In the United Kingdom: Commemorations often include services of remembrance, veteran parades, and tributes to the "Forgotten Army" that fought in the brutal campaigns in Asia. As of 2025, the 80th anniversary is being marked with national events, including a two-minute silence and a service at the National Memorial Arboretum.
In the United States: While it is no longer a federal holiday, observances are still held at war memorials and museums. It is a day to honor the veterans of the Pacific theater and reflect on the sacrifices made to achieve peace.
VJ Day remains a pivotal moment in world history, signifying the end of a global conflict that reshaped the world's political landscape and led to a new era of international relations.
