Shotoku was the 48th imperial ruler of Japan and the sixth woman to hold the position.
Today, she is remembered chiefly for conducting an affair with a Buddhist monk named Dokyo, a man on whom she heaped titles and power. The affair illustrated the growing power of the Buddhist priesthood and was a prime factor in emperor Kammu's decision to move the capital away from Nara in 784.
Empress Shotoku should not be confused with Prince Shotoku (572-622), who was one of the first in Japan to sponsor Buddhism.
