 note = {The Kichijo-ten, a National Treasure, collected at the Yakushiji temple in Nara prefecture is a late 8th century painting on hemp. The National Research Institute for Cultural Properties, Tokyo and the Nara National Museum cooperatively investigated painting materials and drawing techniques of the painting. In this paper, some of the analytical results of X-ray fluorescence spectrometry are presented.
 The following new information about the painting materials was obtained from the present analysis.
(1) White-colored material
 One pigment containing Pb, lead white, was only used for the face, hands and white robe. This pigment was also used for the under-layer of coloring.
(2) Red-colored materials
 Pigments containing Hg (cinnabar) and Pb (red lead) were found from the lip and clothes respectively. A pigment containing Fe (red iron oxide) was found from a bead on the hand.
(3) Green-colored material
 A pigment containing Cu as major component, malachite green and azurite blue was found respectively.
(4) Purple-colored materials

(5) Black-colored material

(6) Gold-colored material
 Pure gold dust paint was used for the decoration on arms and pectoral. 
 Objective discussion of the painting materials of the Kichijo-ten based on the data presented in this paper is expected.},
