Surface carbon films on the weathered Japanese roof tiles were characterized by soft X-ray spectroscopy. From the X-ray absorption measurements, it was confirmed that the surface carbon films were oxidized by weathering. On the ohterhand, from the X-ray emission measurements, it can be confirmed that the degree of the orientation was kept in the inner carbon films.
