The award-winning picture book Sagashite imasu (2012) was published in response to 3/11. It combines dynamic poetics with poignant photographs of relics from the Hiroshima Peace Museum to evoke emotions about extended suffering from radioactive fallout. I argue that the work plays an activist role in prompting an empathetic response which raises an ethical consciousness, and that this kind of response in turn generates a broader “recognition” of the dangers of using nuclear power in (and beyond) Japan after the Fukushima disaster.
