A dense network of colored lines intersects across a white ground, each route labeled with Japanese characters and station names in a geometric grid pattern. The composition uses red, green, blue, yellow, and pink lines to distinguish different transit routes, creating an intricate system map that reads as both functional diagram and visual complexity. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
