Shitennoji is a Buddhist temple located in Osaka. The temple was originally built by Prince Shotoku Taishi in 593. It is the first Buddhist and oldest officially administered temple in Japan. Built by Kongo Gumi (world’s oldest construction company, operating for over 1400 years), the temple has been destroyed many times over the years due to natural calamities and wars. So the buildings of Shitennoji Temple are not original but have been reconstructed each time they were damaged by war or fire. The reconstruction was carried out according to the Buddhist style of original architecture of Asuka period in the decoration and arrangement of the buildings. The temple was last completely rebuilt in 1963, and was built with concrete to fireproof it. The temple precincts cover about 110,000 square meters and are designated as rare historic remains.
