The Kei school (Kei-ha) was the dominant lineage of Japanese Buddhist sculptors from the early Kamakura period into the fourteenth century, and remained influential far longer. Based in Nara, its masters - Kōkei, his son Unkei, and their great contemporary Kaikei - were handed the reconstruction of the city's great temples after the Genpei War of 1180-1185 devastated them, a commission that made the school's fortune. Restoring Tōdai-ji and Kōfuku-ji, they looked back to Nara-period models but carved with a new naturalism: individualized, portrait-like faces, visible sinew and bone, and, for the first time, crystal-inlaid eyes with dark-painted pupils. Favored by the Kamakura shogunate over the court-connected In and En lineages, Kei sculptors set the standard for Japanese Buddhist sculpture for the rest of the medieval period.

Crystal-inlaid eyes with dark-painted centers (hitomane), a Kei innovation giving statues a piercing gaze
Sinew, veins and bone structure modelled beneath robes; sharp, angular drapery folds
Restrained, subdued polychromy compared with earlier Buddhist sculpture
Nara-period (Tenpyō) forms revived and reinterpreted through Kamakura-era realism
Dynamic guardian figures with taut musculature and fierce expressions
