To artist Chiharu Shiota, red—the color of blood—symbolizes the human condition. In her installation Uncertain Journey, over 170 miles of red wool are suspended from the ceiling and walls to create cavernous forms inside the Mori Art Museum as part of The Soul Trembles, the artist’s largest-ever solo exhibition. Below sinuous, veinlike arches, black metal wires create skeletons of boats, which anchor the suspended wool structures to the floor, and, Shiota says, act as metaphors for what propels us through life. “I think we are all connected—an invisible string links our lives,” says the artist. “The boats carry us through a journey of uncertainty and wonder. They carry our collective dreams and hopes for the future.” The piece is on view in Tokyo through October 27.
