It can be divided into the following genres depending on the firing method. As the name suggests, roof tiles called "glaze tiles" or "pottery tiles" produce a variety of colors by applying glaze to the surface of the tiles. "Ibushi tile" has this name because it smokes the tile at the final stage of firing and forms a film containing carbon as the main component on the surface. In Tochigi City, there used to be a lot of roof tile shops that manufacture "Hakonomori roof tiles" because they got good quality clay, but it is cheaper and better quality to purchase from Sanshu in terms of cost with the passage of time. The tiles are getting gone, so they are gradually disappearing. "Glazed roof tiles" are baked without using glaze, and there are kneading methods that mix substances other than clay into the dough, and kiln-shaped roof tiles that pursue natural changes. There is also a "salt-grilled roof tile" that uses salt to bake the surface into a unique reddish-brown color.
