His techniques are identified by the Guggenheim: "Ohashi was known for paintings that integrated the restrained, purposeful act of collage, adding texture and changing registers of density to large, encompassing abstract forms. He added semitransparent layers of rice paper to the foreground of his paintings and, at times, partly obscured the rice paper with layers of oil paint. This technique, combined with large swaths of negative space and occasional highlights in gold leaf, contributes to fluctuating perceptions of space within Ohashi’s compositions".
