Is Japanese society completely homogenous and conformist? Canadian scientist David Suzuki and Japanese anthropologist Keibo Oiwa ask this question, and the answer takes them from Okinawa to Sakhalin Island. Along the way they meet people fighting for social and environmental justice, from indigenous Okinawans and Ainu to ethnic Koreans, feminists, food and environmental activists, and artists who keep the memory of war alive so that future generations may live in peace.
