Victory over Japan Day (VJ Day) is an annual celebration to mark the day Imperial Japan surrendered in World War II.
This surrender, which occurred on August 15 1945, marked the end of the war.
Fighting in Europe had already stopped after Victory in Europe Day (VE Day), on May 8, 1945.
And this year’s celebrations are a special one as it marks 80 years since the momentous event in history.
Here, we take a closer look at the date and how it will be marked this year…
VJ Day, also known as Victory in the Pacific Day, or VP Day, falls this year on Friday, August 15.
The allied victory will be celebrated across the UK. In the US, VJ day is celebrated on September 2, the date on which the surrender document was signed, officially ending the war.
What events will occur in the UK on the day?
Britons are encouraged to join in in a two minute silence at midday on the Friday.
A massive celebratory event will also take place at National Memorial Arboretum to honour VJ veterans and will be broadcast live on TV on BBC One from 11.30am.
The Red Arrows will also join a Spitfire and Hurricane aircraft for a flypast during the VJ Day 80 commemorations.
The Service of Remembrance will “honour and remember those who fought and died during the Second World War in the Far East” with more than 400 members of the Armed Forces, the Red Arrows and historic aircraft from The Battle of Britain Memorial Flight in attendance.
Imperial Japan surrendered after the US dropped two atomic bombs on Hiroshima and Nagasaki, on August 6 and 9, 1945. The Soviet Union also declared war on Japan on August 9, and more than 1.5 million men invaded Manchuko.
Japanese Emperor Hirohito announced Japan would accept the terms of the Potsdam Declaration – which outlined the terms of surrender – on August 15.
US President Harry Truman confirmed Victory over Japan Day at a press conference, while British Prime Minister Clement Attlee announced the victory in a broadcast to the nation.
