Tashiro’s early works were collages composed of images and text cut from newspapers, books, and magazines, forming layered textures and imagined narratives. After working in this style for several years, he shifted focus to the material surface itself—particularly the interaction between two- and three-dimensional planes. Through 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.
