"The Paintings of Hisako Kobayashi are detailed records of her emotions and feelings... Kobayashi is not about feelingness, nothing is casual. Her multi-layered, fresh and ample imagery spans a gamut of presence. At one pole it is tantalizingly bold, often given the solidity of illusionistic volume. Her main painterly impulse is dynamism, meaning the desire to experience a singular and unexpected, almost three-dimensional harmony from the range of her experience."

"Kobayashi understands that questions may be more interesting and illuminating than the certitude of answers. The ambiguous forms in her paintings often seem to float beneath a lustrous glazed, scraped, and scrambled surface. The effect evokes the tantalizing sensation of meanings that are both elusive and insistently present - like the recurring thought that's submerged just at the edge of consciousness."
- Gerard Haggerty
"Kobayashi uses color in a more modulated fashion, creating more depth of field in her works. On occasion, one can see shapes and pools of color that have been painted over linger beneath the surface.
What makes the paintings work, however, is the artist's flair for mark making. On some of her canvases, the lines are as fine and dense as the bristles on a make-up brush. In others they are road and coarse, as loosely and hastily scrawled as graffiti on the wall of a subway station."
