Tarō Okamoto became world-famous by designing the “Tower of the Sun” at Expo ’70 in Osaka. The ideas and problems that came with its creation, however, are intertwined with the evolution of Japanese culture – from the Paleolithic up until modern times. In his documentary debut, director Kōsai Sekine takes us on a philosophical journey that transcends the visual limits of documentaries.

A program to learn about the works, words, and ideas of Taro Okamoto while enjoying the "fictional history" of TAROMAN, which was produced under the day of broadcasting in 1972. How was TAROMAN born? What message did he convey in other programs in which he made a series of guest appearances as his popularity grew? What influence did he have on later creators? The full version of the theme song "Explosion! Taro Man" was also performed for the first time. The navigator is Arata Iura, who loves Taro Okamoto.
