Influenced by Minimalism, Yu Hiraishi\'s jewelry reflects her sculpture and installations, for which she is well-known in Japan, her country of origin. Brooches, necklaces, bracelets, and earrings are constructed from basic three-dimensional forms such as cylinders, tubes, and pipes, asymmetrically bent rods, or flat, geometric shapes that intersect at oblique angles. Deceptively simple, these \"primary structures\" suggest natural phenomena like leaves, flowers, and waves, in their most abstract iterations. The addition of monochromatic primary colors, painted with urethane paint on the brass surface of each piece, make the works \"pop\" as well as serving to intensify a rhythmic play of light and shadow; many pieces are constructed in a manner that allows the viewer to appreciate all sides simultaneously.
Hiraishi received an undergraduate degree from Musashino Arts University in Tokyo, in 1970. her lengthy career includes numerous solo exhibitions at galleries throughout Japan. She has shown in many group exhibitions, most notably Elegant Armor: The Art of Jewelry, at the Museum of Arts and Design in New York, in 2008, where she also has a piece in the permanent collection.
