Tōdai-ji is famous for housing Japan's largest bronze Daibutsu Buddha statue within its Great Buddha Hall (Daibutsuden), which is one of the world's largest wooden buildings, and for being a UNESCO World Heritage Site containing other significant treasures. The temple, a historically important Buddhist complex founded in the 8th century, also serves as the Japanese headquarters for the Kegon school of Buddhism. The temple's main attraction is a massive bronze statue of the Buddha Vairocana (Daibutsu). The hall housing the Daibutsu is one of the largest wooden buildings in the world. It is listed as one of the "Historic Monuments of Ancient Nara," a collection of historically significant sites. Tōdai-ji was the principal temple of the Kokubun-ji system, a network of national temples established for national peace and the training of monks.
