Yoshioka's interests are found in combining abstract expressions and industrial production. Since 2015, the base material itself has become the theme of his paintings, as a means to remove from his work, factors that are intrinsic to the subject. The colorful canvas copies that exist as moderators of the physical and two-dimensional representation in paintings, are created by molding a single canvas repeatedly using acrylic paints. As the painting is done on the mold, the impasto and textures stay underneath the surface of the paint, unable to be seen. After the paint is released from the mold, it develops into a hand-craft object disconnected from accuracy, as it is cut and collaged as test of intuition. His practice of visualizing changes in aspect, when information is converted and documented onto a different medium from the original, suggests the uncertainty of the perceptions that we experience, as mediators between the physical and virtual world.
