Focus on this artwork and analyze the Style.
The style of this statue is reflective of the transitioning attitudes and ideals observed in the early Kamakura period. During this time Japan faced a shift from the nobility that governed the late Fujiwara period to the "landowning military men" that seized power at the start of the Kamakura period. Dramatic shifts in politics, society, and culture resulted in a transformation of artistic design, with focus placed heavily on realism and honesty. Additionally, the Kamakura era marked a turning point in religious activity, with Buddhism becoming more heavily practiced among the masses  Stylistically, Ksitigarbha Bodhisattva (Jizō Bosatsu) reflects this shift towards Buddhism in its depiction of the Bodhisattva, as well as the realism of early Kamakura art in the "highly stylized geometric" shaping of the statue's head and torso.
