Tejaprabha Buddha paintings are based on constellation themes. Along with Chinese Tantric paintings, these were introduced to Japan during the early ninth century. Most of these paintings were heavily influenced by classic rituals of Chinese Tantra, which were brought to Japan from Tang Dynasty China by Ennin during year five of the Jowa Era (838 A.D.). Tejaprabha Buddhism doctrine practices were used by the Japanese court to bless the nation with security and peace. After its introduction to Japan, Tejaprabha Buddha paintings continuously changed over time to suit the needs of each era. Through study and comparison of Japanese Tejaprabha Buddha paintings, this essay attempts to examine changes in Japanese Tejaprabha Buddha paintings over the course of time and incorporated Japanese elements to understand the meaning behind these images.
