Fujiko Nakaya's artistic work was characterized early on by its proximity to science. In 1966, she joined the group E.A.T. - Experiments in Arts and Technology, which was founded by artists and engineers. Against the background of rapidly developing communication technologies, E.A.T. pursued the creation of works of art that employed the latest technical possibilities. At the same time, artists and scientists were intended to learn from one other. Fujiko Nakaya had represented E.A.T. in Japan since 1969. For the 1970 World's Fair in Osaka, she worked with E.A.T. to create her first large fog sculpture for the Pepsi Pavilion.
