Jōchō is said to be one of the greatest Buddhist sculptors not only in Heian period but also in the history of Buddhist statues in Japan. Jōchō redefined the body shape of Buddha statues by perfecting the technique of "yosegi zukuri" (寄木造り) which is a combination of several woods. The peaceful expression and graceful figure of the Buddha statue that he made completed a Japanese style of sculpture of Buddha statues called "Jōchō yō" (Jōchō style, 定朝様) and determined the style of Japanese Buddhist statues of the later period. His achievement dramatically raised the social status of "busshi" (Buddhist sculptor) in Japan.
