Born in Kyoto in 1974. Miyanaga graduated from Kyoto University of Art and Design (now as Kyoto University of the Arts) with a BA in sculpture in 1999 and completed her MFA in Intermedia Art from Tokyo University of the Arts in 2008. She creates sculptures using naphthalene crystals. Producing sculptures with naphthalene, which has the nature of being extremely prone to sublimation, is a constant battle against vanishment. Miyanaga’s works are sealed in glass cases or completely covered with resin, but once air enters the internal environment with the temperature impact, they begin to sublimate and disintegrate in the blink of an eye. However, despite the viewer’s anxiety towards the sublimation, Miyanaga does not feel pessimistic about losing the sculpture as an individual because naphthalene is easily sublimated but also easily crystallized at the same time. Even after it transforms into gas, it recrystallizes in the container, and the work (what it used to be) continues to exist while changing its shape into another form. This state of the existence of Miyanaga’s works suggests many things. For example, the relationship between the human body and spirit, the relationship between time and space, the nature of continuously changing material. There is no everlasting substance that exists in this world. Major museum solo exhibitions include “Miyanaga Aiko: Rowing Style” (Takamatsu Art Museum) in 2019, “between waxing and waning” (Ohara Museum of Art, Yurinso, Okayama) in 2017, “Miyanaga Aiko: Nakasora - The Reason for Eternity” (The National Museum of Art, Osaka) in 2012. Moreover, she received a grant from the Asian Cultural Council (ACC) to study in the USA in 2006 and from the Japanese Government Overseas Study Program for Artists (2006, 18th year of the Heisei era) to study in the UK in 2007. She received “The 70th Minister of Education Award” for New Artist in Fine Arts in 2020, “Nissan Art Award” Grand Prize in 2013, “The 22nd Gotoh Memorial Foundation” Newcomer’s Prize for Art in 2011 etc... She has participated in numerous international exhibitions and group shows in Japan and abroad.
