Tōdai-ji is a Buddhist temple complex that was once one of the powerful Seven Great Temples, located in the city of Nara, Japan. Though it was originally founded in the year 738 CE, Tōdai-ji was not opened until the year 752 CE. The construction of the temple was an attempt to imitate Chinese temples from the much-admired Tang dynasty. The temple has undergone several reconstructions since then, with the most significant reconstruction taking place in 1709. Its Great Buddha Hall houses the world's largest bronze statue of the Buddha Vairocana, known in Japanese as Daibutsu (大仏). The temple also serves as the Japanese headquarters of the Kegon school of Buddhism. The temple is a listed UNESCO World Heritage Site as one of the "Historic Monuments of Ancient Nara", together with seven other sites including temples, shrines and places in the city of Nara.

Daibutsu or 'giant Buddha' is the Japanese term, often used informally, for large statues of Buddha. The oldest is that at Asuka-dera (609) and the best-known is that at Tōdai-ji in Nara (752). Tōdai-ji's daibutsu is a part of the UNESCO World Heritage Site Historic Monuments of Ancient Nara and National Treasure.
