<p>For the four paintings in the first volume of the Nara-ehon "Taketori Monogatari", made in the early Edo period (1661-1681), point and two-dimensional analyses were carried out with an X-ray analytical microscope at room temperature under atmospheric conditions. The fluorescent X-ray spectrum of the washi used confirmed the presence of small amounts of Si, P, S and K, and it was very similar to that of a Torinoko-gami that was quite expensive but common in Japan of the Edo era. By point analyses of the four paintings, various pigments, such as vermillion (HgS), minium (Pb₃O₄), marachite (Cu₂CO₃(OH)₂), azurite (Cu₃(CO₃)₂(OH)₂), chalk (CaCO₃), gold and silver, were found to be used. The point analyses were performed on the eight gray-blue areas in the four paintings. In all parts Co was detected together with Si, Fe and As. These results suggest that a cobalt ore with a high probability of smalt was selected for coloring gray-blue. There are three types of blue colorants in the fourth painting: azurite, indigo as a dye and the cobalt ore. It was confirmed that the production period of the Nara-ehon "Taketori Monogatari" was in the early Edo period consistent with its appraisal.</p>
