In recent years, Japan has witnessed the 2011 Fukushima nuclear disaster, a rise in racist hate speech, and the reinterpretation of the constitution to enable state militarization. In response to these crises, a segment of Japanese activists has adopted antifa to bolster their ongoing participation in antinuclear, antiracist, and antiwar social movements. This intervention focuses on what the author calls liberal antifa. Informed by its vexed relationships to the Japanese New Left, liberal antifa in Japan attempts to encompass a broad spectrum of political positions including liberal, left-wing, and even right-wing activism. This intervention traces linkages between liberal antifa and the resurgence of protest after Fukushima, drawing on ethnographic observations and interviews to analyze opposition to fascism within multiple, overlapping social movements. The author also shows how liberal antifa borrows from transnational influences to blend radical and popular cultural practices in relation to music, fashion, art, and food.
