In the Expo Memorial Park in Suita, Osaka you can see "Tower of the Sun" by Taro Okamoto.
The sculpture was created for the Expo ( World Fair ) in 1970. It represents the past, present and future of the human face, they say.
For a long time it stood inside a metal structure and was hard to view completely. Now it stands exposed and can be viewed easily. It faces the main gate and welcomes the visitors. It is indeed impressive.
A friend of mine and I were talking about the Expo recently.
The design of the pavilions looks so futuristic and refined. It is very 70s, but at the same time full of timeless imagination.
There is also a nice Japanese garden in the park.
It features a sizable pond with koi ( carp ) and a bamboo forest.
