In the early 1950s, works by Yoshihara were featured in the opening shows of Nihon Kokusai Bijutsu-ten (International Art Exhibition Japan) and Gendai Nihon Bijutsu-ten (Contemporary Art Exhibition of Japan) during the resurgence of contemporary art in Japan. In "Osaka 1951", Yoshihara and others established the "Gendai Bijutsu Kondankai" (Contemporary Art Discussion Group), known as "Genbi". This group served as a workshop and forum for creating new art forms merging Eastern and Western culture as well as the modern and traditional. The main focus of Yoshihara was gaining recognition in the art world through Japanese tradition and in 1952 Yoshihara participated for example to the Salon de Mai in Paris and again in 1958 after the visit of Georges Mathieu to Japan in 1957 and the discovery of the movement by the art critic Michel Tapié.
