Osaka was the the site of Expo ’70, and among the most memorable elements of the event, standing to this day, is the "Tower of the Sun", a 70-metre-tall sculpture/building envisioned and designed by renowned artist Taro Okamoto, who some call “the Japanese Picasso”. This film is a theatrical adaptation of "TAROMAN", a tokusatsu series re-envisioning Okamoto's most famous pieces as surrealist superheroes and villains, with Ultraman-like TAROMAN, based on the Tower itself, at the forefront of it all.

Actor and Taro Okamoto fan Arata Iura narrates this mockumentary surrounding the 1972 tokusatsu series "TAROMAN", its impact on contemporary 1970s Japan, the ties to popular art with its motifs influenced by artist Taro Okamoto, and the lasting impact the series had on creators decades down the line. Also, performed for the first time is the theme song for "TAROMAN", "Explosion! TAROMAN".
