Yuko Nasaka was born in 1938. The circle, as a personal motif, figures prominently in her work.
Early in the 20th century, Frottage (textural effects or impressions from rubbings) and grattage (a scraping technique) were both accidental discoveries made by artists during the creative process; they produce surprising marbling and veining on the surface, and
create textures not normally possible with ordinary watercolor or oil techniques.
Japan in the' 60s was becoming ever more industrialized. Yuko Nasaka experimented with the use of new industrial materials in painting; in her work, sometimes resembling relief sculpture, she carved circles like the grooves of vinyl LP recordings, then coated them with enamels from a paint gun for greater texture and brilliance. Given that her family operated a factory, her feeling for the round dials of measuring devices seems to have become unconsciously bound up with the sculpted shapes in her works.
