The 75th anniversary of VJ Day (Victory over Japan) will be recognised on 15 August 2020 commemorating the final end of the Second World War.
This anniversary is rarely ‘celebrated’ publicly as widely as VE Day but it was, never the less, just as important for many reasons.

On August 6th, at 8.15 a.m. Japanese time, the United States dropped the atomic bomb ‘little boy’ on Hiroshima and on August 9th at 11.02 a.m., dropped the bomb ‘fat man’ on Nagasaki. This resulted in the Japanese formally surrendering to the Allies on August 15th.
This was made official on September 2nd 1945 with the signing of the Japanese Instrument of Surrender aboard the battleship USS Missouri in Tokyo Bay.
