The introduction of Buddhism into Japan in 538, also brought many architects from the Korean peninsula with new techniques reflecting the Chinese (Northern Wei) style of Buddhist architecture. Horyuji, a temple in Nara whose main hall and pagoda date back to the Asuka period, was built in this style. Architecture during the Nara period (710-794) was influenced by the Tang style which was characterized by stable and balanced proportions and by an emphasis on structure over ornamentation. The lecture hall of Toshodaiji, a temple in Nara, is one of the finest representations of this style.
