The Japanese concept of yohaku no bi refers to space intentionally left blank in a work of art, an absence that brings harmony to a composition. For the prominent Zen painters of Japan, yohaku represented nothingness. These painters, including the 16th-century Japanese master Tōhaku Hasegawa, served as inspiration to the contemporary artist Takesada Matsutani, Osaka-born and Paris-based. Following Matsutani’s first major survey at Paris’s Pompidou, a selection of the artist’s work exploring yohaku through monochrome is on display at Hauser & Wirth, Zurich. —J.V.
