Expo '70 (日本万国博覧会 Nihon bankoku hakuran-kai ) was a World's Fair held in Suita, Osaka, Japan between March 15 and September 13, 1970. The theme of the Expo was "Progress and Harmony for Mankind." In Japanese Expo '70 is often referred to as Ōsaka Banpaku (大阪万博). This was the first World's Fair held in Japan.
Like the 1964 Summer Olympics, Expo '70 was a success and served as a symbol of the extremely rapid development of Japan in the 1960s. It was held in Suita, a suburb of Osaka. When it was chosen as the site for the event, it was a rural district covered with bamboo forest. For Expo '70 infrastructure was created and the surrounding area was developed. The site for the world fair was planned by the Japanese architect Kenzo Tange.
A popular highlight of the fair was a large moon rock on display in the United States' pavilion. It had been brought back from the moon by Apollo 12 astronauts in 1969. Expo '70 also saw the premiere of the first-ever IMAX film: the Canadian-produced Tiger Child for the Fuji Group pavilion. The Expo also featured demonstrations of early mobile phones, local area networking and maglev train technology. Seventy-seven countries attended the event and, within six months, the number of visitors reached 64,210,000 people, one of the largest and best attended expositions in history.
The site of Expo '70 is now Expo Commemoration Park (万博記念公園 Banpaku kinen-koen ). Almost all pavilions were demolished, and there remain some memorials a part of the roof structure for Festival Place (お祭り広場 O-matsuri hiroba ) designed by Kenzo Tange. Among a few still-intact pieces, the most famous one is the Tower of the Sun (太陽の塔 Taiyō-no tō ) designed by the Japanese artist Okamoto Taro. The former international art museum pavilion designed by Kiyoshi Kawasaki was used as the building for the National Museum of Art, Osaka (moved to downtown Osaka in November 2004) until March 2004.
Additionally, there is a time capsule that is to be left for 5,000 years and opened in the year 6970. The capsule has been donated by the Matsushita Electric Industrial Co. This World's Fair concept first originated and started with the two Westinghouse Time Capsules which are to be opened in 6939.
