In Japanese, Utsurohi means a moving, floating state. The work consists of 25 luminous steel pillars 30 cm in diameter, covered in crystallized glass and linked by steel rods. The artist gives them a cheerful name: drawings of air.

Miyawaki Aiko is an abstract sculptor who exhibits her work outdoors in Japan, then in France, the United States and Spain.

Her aim is to invest the three dimensions of space on the two-dimensional supports of painting, her preferred art form, which she gave up practicing in 1968. To this end, she created works called Utsurohi.
