In 1965, Gutai's fame was spreading in Europe, and Jiro Yoshihara was invited to participate in an exhibition in Amsterdam, the Netherlands, where he traveled there with his second son Michio, a member of Gutai. The exhibition refused to show paintings, and only three-dimensional works and other new fields that had never been exhibited before were requested. Yoshihara exhibited nine works that had been well received at the open-air exhibition and two new works by Michio. The exhibition featured the new European avant-garde groups "Null," "Zero," and "Gutai“. The exhibition impressed the audience with the uniqueness of Gutai's work and positioned them as an outstanding avant-garde art group, unique but contemporary.
At the same time, it stimulated the younger members to create their own works, giving rise to a variety of ideas, and triggering a return from painting to the experimental work of the early years of the group.
