Aiko Miyanaga has created works that visualize time, such as objects shaped like everyday items like shoes, watches, and bags made of naphthalene, and installations using salt. These works, which change over time, appear fragile and delicate at first glance, yet simultaneously embody the image of eternity, the idea that all things with form are subject to change. This book features her representative and latest works. It introduces the world and thought process of Aiko Miyanaga, whose works are free from stereotypical thinking and possess an infinite expanse. This is her first collection of works. Official catalog for the exhibition "Aiko Miyanaga: Nakasora - Air in the Sky" at the National Museum of Art, Osaka.
