Hi-Red Center (ハイレッド・センター, Haireddo Sentā) was a Japanese artistic collective, founded in May 1963 and consisting of artists Genpei Akasegawa, Natsuyuki Nakanishi, and Jiro Takamatsu, that organized and performed anti-establishment happenings. Taking the urban environment of Tokyo as their canvas, the group sought to create interventions that would raise questions about centralized authority and the role of the individual in society.
