Tower of the sun

Kosai Sekine


Half a century after the Osaka Expo, Taro Okamoto's Tower of the Sun is still a symbol of Osaka and continues to fascinate people. This is the first and last documentary film about the Tower of the Sun. What exactly is the Tower of the Sun?

In 1970, Japan was in the midst of a period of rapid economic growth, and the Osaka Expo was held under the theme of "the progress and harmony of mankind. The Tower of the Sun, created by the avant-garde artist Taro Okamoto, stood out from the crowd. Why is it that the Tower of the Sun still fascinates people today? Why did only the Tower of the Sun survive? We will try to answer these questions.
A total of 29 people were interviewed, including not only those involved in the creation of the Tower of the Sun at the time of the Expo, but also experts on Taro Okamoto, scholars and critics in various fields, and contemporary artists and artists of expression. The film consists mainly of interviews with the interviewees, but it also explores the roots of Taro Okamoto and the theme of "Myth of Tomorrow," which was created at the same time, to highlight the message from the Tower of the Sun. Through the Tower of the Sun, Taro Okamoto continues to provoke humanity.
