Kuroaya is a tile with a Yohen glaze finish. (It is the most popular Japanese traditional ceramic finish.) Aya means coloring. The deep glaze color reflects high-quality materials, and the bright black background of the tiles creates a classy atmosphere. The deep blue and red colors that emerge when a light shines through are two traditional shades in Japan.
