"Mother River Homing" by Mari Katayama is a photography book featuring a trilogy of her series: "Shadow Puppet" (2016), "Bystander," and "On the way home." Having lost her legs at nine, Katayama relies on prosthetics, integrating her own body prominently in her work. Through self-portraits with humor and complex visual orchestration, she challenges beauty ideals, examines health and femininity, and explores the mind-body connection. "Bystander" includes images of her on a beach with handmade legs, evoking mythical figures. Her work further portrays oversized pillow limbs within family portraits, emphasizing their own presence and significance.
