The economic legacy of the London Olympics two years ago has reached £13 billion, according to new figures.
Companies have continued to secure contracts at home and abroad as a direct result of the 2012 Games, while British firms could benefit from future Olympics.
Japanese Prime Minister Shinzo Abe will visit the Olympic Park in east London tomorrow to witness the signing of a memorandum of co-operation paving the way for close collaboration between his country and the UK over the planning of the 2020 Games in Tokyo and the 2019 Rugby World Cup in Japan.
Trade and Investment Minister Lord Livingston said: "I am delighted that Japan has signalled that it wants to use UK expertise to help deliver both the Tokyo Olympics and Rugby World Cup.
"The delivery of London 2012 on time and under budget has shown the world that the UK has a significant amount of expertise in staging large-scale events."
