For Yayoi Kusama, her age and the scale of her installations have always gone hand in hand. In 1956, in her hometown of Matsumoto, she had her first solo exhibition—watercolors. It was received with indifference. In 1965, she displayed her first Infinity Mirror Room—Phalli’s Field—a small mirrored room filled with stuffed phalli, white forms painted with red polka-dots. After that, the rooms got bigger. Now 94, she’s unleashing her largest installation yet. A cavern of undulating curves covered in orange spots (are we inside a giant anemone?) will inhabit the Factory International. It’s the first museum show dedicated to Kusama’s balloons, and a major curtain raiser for the U.K.’s newest museum. —Elena Clavarino
