Heijō-kyō, modern day Nara, was founded in 708 as the first permanent capital of the state of Japan. The layout of its checkerboard streets and buildings were modeled after the Chinese capital of Chang'an. The city soon became an important centre of Buddhist worship in Japan. The most grandiose of these temples was Tōdai-ji, built to rival temples of the Chinese T'ang and Sui Dynasties. Appropriately, the 16.2-m (53-ft) Buddha or Daibutsu (completed in 752) enshrined in the main hall is a Rushana Buddha, the figure that represents the essence of Buddhahood, just as Tōdai-ji represented the centre for imperially sponsored Buddhism and its dissemination throughout Japan. Only a few fragments of the original statue survive, and the present hall and central Buddha are reconstructions from the Edo period. Clustered around the main hall (the Daibutsuden) on a gently sloping hillside are a number of secondary halls: the Hokke-dō (Lotus Sutra Hall), and the storehouse, called the Shōsō-in, and the adjoining Kōfuku-ji. This last structure is of great importance as an art-historical cache, because in it are stored the utensils that were used in the temple's dedication ceremony in 752, as well as government documents and many secular objects owned by the Imperial family.
