ten most popular pavilions at the exhibition with its dramatic roof sweeping up from the ground using fine Philippine hardwoods and other native materials. Other attractions 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 conveyor belt sushi, early mobile phones, local area networking and maglev train technology. Today The site of Expo '70 is now Expo Commemoration Park. Almost all pavilions have been demolished, but a few memorials remain, including part of the roof for Festival Plaza designed by Tange. The most famous of the still-intact pieces is the Tower of the Sun. The former international art museum pavilion designed by Kiyoshi Kawasaki was used as the building for the National Museum of Art, Osaka until March 2004 (the museum moved to downtown Osaka in November 2004). Additionally, there is a time capsule that is to be left for 5,000 years and opened in the year 6970. The capsule was donated by The Mainichi Newspapers Co. and the Matsushita Electric Industrial Co. The concept creating time capsules at world's fairs started with the two Westinghouse Time Capsules, which are to be opened in 6939. Part of the Expo Commemoration Park is now ExpoCity, a shopping mall that features the Redhorse Osaka Wheel. Osaka successfully bid for Expo 2025 alongside Yekaterinburg, Russia and Baku, Azerbaijan. However, the world's fair will not reuse the park space, and will instead be hosted on Yumeshima island in Konohana, on the waterfront of Osaka Bay. 50th anniversary Celebrating the 50th anniversary of Japan World Exposition began in Osaka in 1970, "Expo ’70 50th Anniversary Special Exhibition" was held in Tennozu area of Tokyo from February 15 to 24, 2020.
