Tashiro’s early collages layered fragments of text and imagery from newspapers, books, and magazines, forming textured compositions that evoke imaginary and surreal narratives. Over time, his focus shifted toward the materiality of the surface itself, particularly the interaction between two- and three-dimensional planes. Through explorations in carving and mark-making, he began cutting and gouging into wooden surfaces, layering them with paper, pigments, inks, and found materials to create abstract compositions of colour and form that merge sculpture with collage.
