With her photography, Tonomura revealed her deepest pain and dark family secrets, including her mother’s love affair with another man. The subject of the photographs i.e. mama in mama love (2008) series, is fully aware of the existence of the camera, at times even looking into the camera. She appears as the victim in her different relationships within her family and the society. These photographs are confrontational and painful to look at, they are at the same time filled with violence and love. Nobuyoshi Araki writes the Obi for this photo book saying "Playing around with the darkness."
