Japan's first permanent capital was laid out on a Chinese grid in 710, and within a generation the court had decided that Buddhism was an instrument of government. Emperor Shomu ordered a monastery and a convent in every province, each holding copies of protective scriptures, and in 743 announced the casting of a colossal image of the cosmic Buddha Vairocana as the centre of that system. The monk Gyoki, who had been building bridges and irrigation works and preaching to ordinary people in defiance of restrictions on doing so, was recruited to raise subscriptions.
The image consumed an enormous quantity of bronze and gold and took years to cast in stages. At the eye opening ceremony in 752 an Indian monk painted in the pupils with a brush, cords were run from it so that the assembled thousands could share the act, and dancers and musicians performed pieces from China, Korea and further west. The offerings presented at that ceremony were stored in a raised timber repository beside the temple and are still there, the oldest intact treasury of its kind anywhere.
The six schools of Nara Buddhism were academic traditions studied within temples rather than sects with congregations, and a monk could work in more than one. The court also worried about ordination being taken lightly, and after five failed voyages the Chinese master Ganjin arrived, by then blind, to establish a proper ordination platform, so that Japanese monks were monks by a recognised procedure.
