The History of World Expositions

[Home(EXPO 2000)]


After first having to abandon the Japanese World Exposition of 1912 in the planning stage (für following the death of Emperor Meji, and then the Japanese World Exposition of 1940 following the outbreak of the Second World War, efforts started again in earnest in 1963 to organise a World Exposition on Japanese soil. This third attempt was officially registered in May 1965 with the Bureau International des Exposition (BIE) in Paris. The decision of the BIE went in Japan's favour not only because of the two earlier unsuccessful attempts but also - indeed primarily - because of the economic upsurge of Japan since the war and the successful organisation of the Olympic Games in Tokyo in 1964. Osaka, a highly industrialised city and the second largest in Japan, was host to the first Asian World Exposition. The hill at Senri, a satellite town around 50 km to the north of the city centre, was chosen as the site of the exposition to be created around the theme "Progress and Harmony for Mankind".

While the Japanese government was responsible for finance and control, a company called "Japan Association for the 1970 World Exposition" was established to take on the preparation, planning and realisation of the event. Kenzo Tange, Uzo Nishiyama and Kazumi Iinuma presented the master-plan for the grounds in October 1966. A committee was set up to develop the exhibition site working under the leadership of Shigeru Ito. In January 1968 the final design drawings were ready. On 14 March 1970, EXPO '70 was officially opened by the Emperor and the Empress of Japan.
