What is "dainichi nyorai"

n. (context mythology Buddhism English) Dainichi Nyorai; the Japanese name for the sun Buddha, Vairocana, one of the Five Dhyani Buddhas.

The at the Shingon temple of Enjō-ji in Nara is the earliest and best-substantiated work by Japanese master sculptor Unkei. An inscription on the pedestal records that he began work on the piece in 1175 and brought it to completion the following year. The sculpture has been designated a National Treasure. Unkei's next documented works, from the early 1180s, were commissioned by military leaders prominent in the ensuing Kamakura shogunate, for temples in eastern Japan. These works are physically more massive and powerful, as are his giant Niō at Tōdai-ji. By contrast, in this early work Unkei employed a more "gentle" or "tranquil" style.
