Born around 1150 (dates uncertain), eldest son of the sculptor Kokei, from the prominent Kei school (Nara sculptors). Trained under his father, he became the leading figure of the Kei school while still young. Boldly overturning the gentle, graceful "Jocho style" established in late Heian sculpture, he created a new mode of powerful physicality and spiritual intensity. The Kongo Rikishi (Nio) statues—completed with Kaikei in 1203 for Todai-ji's Great South Gate—are said to have been carved by the two sculptors in just 69 days. Each stands about 8.4 meters tall; they are Japan's largest wooden Buddhist sculptures and national treasures. His portrait sculptures of Mujaku Bosatsu and Seshin Bosatsu at Kofuku-ji (around 1212) capture the living human form with such startling realism that they are considered the pinnacle of portrait sculpture. He produced numerous images at Todai-ji and elsewhere, supported vigorously by warrior patrons including Minamoto no Yoritomo and Ashikaga Yoshikane. He died around 1224. He is counted among the greatest sculptors in Japanese art history.

An innovative artist who boldly pursued realism while respecting tradition. His works embody the vigor resonant with warrior spirit and deep Buddhist devotion.

The greatest Buddhist sculptor in Japanese history. The Todai-ji Nio are the pinnacle of national treasures. Kamakura-era sculptural realism is inseparable from Unkei, whose influence extends to modern Japanese art.
