The Expo attracted international attention for the extent to which unusual artworks and designs by Japanese avant-garde artists were incorporated into the overall plan and individual national and corporate pavilions.

[3] The most famous of these artworks is artist Tarō Okamoto's iconic Tower of the Sun, which still remains on the site today.

330 hectares in the Senri Hills outside Osaka had been earmarked for the site and a Theme Committee under the chairmanship of Seiji Kaya was formed.

These architects included: Arata Isozaki for the Festival Plaza mechanical, electrical and electronic installations; and Kiyonori Kikutake for the Landmark Tower.

The designers thought that unlike previous expositions they wished to produce a central, unifying, Festival Plaza where people could meet and socialise.

Tange envisioned that the exhibition for the future would be like an aerial city and he asked Fumihiko Maki, Noboru Kawazoe, Koji Kamiya and Noriaki Kurokawa to design it.

The flexibility extended to the lighting and audio visual equipment allowing for a range of musical performances and electronic presentations.

[10] Seventy-seven countries participated in the event, and within six months the number of visitors reached 64,218,770, making Expo '70 one of the largest and best attended expositions in history.

[28] Expo '70 also saw the premiere of the first-ever IMAX film: the Canadian-produced Tiger Child for the Fuji Group pavilion.

[29] The Expo also featured demonstrations of conveyor belt sushi,[30] early mobile phones, local area networking and maglev train technology.

[citation needed] Part of the Expo Commemoration Park is now ExpoCity, a shopping mall that features the Redhorse Osaka Wheel.

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.
