In the early Heian period (794 to about the mid-10th century), statues of esoteric Buddhism flourished. Kūkai, Saichō and other members of Imperial Japanese embassies to China imported the high to later Tang style. The statue bodies were carved from single blocks of wood and appear imposing, massive, and heavy when compared to Nara period works. Their thick limbs and severe, almost brooding facial features imbue them with a sense of dark mystery and inspire awe in the beholder, in keeping with the secrecy of Esoteric Buddhist rites. Heavily carved draperies, in which rounded folds alternate with sharply cut folds are typical of the period.
