Born in Tokyo, Japan in 1974. Aoshima graduated from the Faculty of Economics, Hosei University in 1995. She made her debut with illustrations that made full use of the "Bézier curves" of Adobe Illustrator, and joined Kaikai Kiki, led by Takashi Murakami. She later moved on to hand-painted works, while also presenting animations and sculptures. The distinctive character designs born of the Bézier curves of her debut have carried through consistently: the undulating hair, the clouds and water that appear to draw on Nihonga (Japanese-style painting), and the gradations come close to the multicolor printing of ukiyo-e. Aoshima continues to attract attention as one of the artists who embody the new pictorial space described by Murakami's "Superflat" theory. Her work is characterized by ghosts, yokai and other uncanny beings, girls who seem fragile, and vivid, pop depictions of plants and animals. As if to reconcile cruelty with cuteness, direct allegories of death such as grave markers and skeletons coexist in a single picture with representations of life: lush flowers, insects and birds in flight, and the supple limbs of girls. Beginning with an appearance in "Superflat" (2001), the landmark exhibition that Murakami launched to the world (which toured to the Museum of Contemporary Art, Los Angeles, the Walker Art Center and other venues), she has exhibited at museums and other venues abroad one after another since early in her career. Major solo exhibitions include the Musée d'art contemporain de Lyon (2006), the Institute of Contemporary Art/Boston (ICA) in the same year, the Museum of Fine Arts, Houston (Texas, 2007), the Fundació Joan Miró (Barcelona, 2008) and the Seattle Art Museum (2015). Her works are in the collections of major contemporary art museums including the Carnegie Museum of Art (Pittsburgh), the Seattle Art Museum, the Museum of Contemporary Art, Los Angeles and the Museum of Contemporary Art Chicago.
