Shitennō-ji is a Buddhist temple in Ōsaka, Japan. It is also known as Arahaka-ji, Nanba-ji, or Mitsu-ji. The temple is sometimes regarded as the first Buddhist and oldest officially-administered temple in Japan, although the temple complex and buildings have been rebuilt over the centuries, with the last reconstruction taking place in 1963. Shortly after World War II, Shitennō-ji became independent of the parent Tendai sect, and formed the "Wa" sect of Buddhism.
