This paper argues that the interwar Japanese Marxists Miki Kiyoshi and more contemporary Hiromatsu Wataru each moved towards developing this perspective beyond simple distinctions between idealism, which is confined to concepts, and materialism, conceived as presupposing that ideas are determined by matter. Japanese Marxism was in a unique place to affect such a synthesis because of the existence of Kyoto School philosophy, with whom both Miki and Hiromatsu were associated. The proponents of the Kyoto School combined Eastern and Western philosophical perspectives, which had the aim of criticizing modernity. Miki Kiyoshi and other members of the Kyoto School eventually supported Japan's wartime effort, which delegitimized their concerns about modernity during the postwar. However, in postwar Japan, Hiromatsu developed a creative reading of Marx's materialism and in the 1994 surprised everyone by advocating a pan-Asianist critique of modernity. Hiromatsu suggested that despite problems that Miki and the Kyoto School represented, one had to grasp the rational kernel, which could save Marxism from slipping into an equally dangerous modernization theory. This task remains for us today when the dystopia of globalized capitalism seems to have become a reality that threatens the survival of our planet.
