Shitennō-ji

Shitennō-ji (四天王寺, Temple of the Four Heavenly Kings) 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 (wa-shū, 和宗) of Buddhism.

History
Prince Shōtoku was known for his profound Buddhist faith when Buddhism was not widespread in Japan during the 6th century. In order to popularize Buddhism, Prince Shōtoku led a massive national project to promote Buddhism and he commissioned the construction of Shitennō-ji. Prince Shōtoku invited three Korean carpenters from Baekje. They brought knowledge and led the construction of Shitennō-ji. The commission of Shitennō-ji was part of a massive national project led by Prince Shōtoku.

The temple buildings themselves have been rebuilt a few times over the centuries; most of the present structures are from when the temple was last completely rebuilt in 1963. One of the members involved in the initial construction of the temple in the 6th century later established the firm Kongō Gumi, which specialized in temple and shrine buildings. Kongō Gumi was the world's oldest company until it was acquired by the Takamatsu Construction Group in 2004.

Description
"Shitennō" refer to the Four Heavenly Kings in Buddhism. The temple Prince Shōtoku built to honor them had four institutions, each to help the Japanese attain a higher level of civilization. This Four Institutions (四箇院) was centered on the seven-building garan (伽藍) (the complex inside the walls), and included a Institution of Religion and Education, a welfare Institution, a hospital, and a pharmacy to provide essential care to the people of Japan. Three of the four sections are known to have existed inside the temple in Kamakura period.

The consists of a five-story pagoda, a main Golden Pavilion  housing an image of the Bodhisattva Kannon, and a Lecture Hall under a covered corridor holding three gates; the Deva Gate (仁王門) (also known as the chūmon (中門)), the Western Gate, and the Eastern Gate. Surrounding this central complex are the Great South Gate, and a Great East Gate. To the west is the Great West Gate, also known as Gokuraku-mon (極楽門). Further to the west is a stone torii, which is imagined to be the Eastern Gate to Sukhavati, the Pure Land of the West.

In the Kameido hall is a 7th-century turtle-shaped stonework that was used for state rituals with water. These are 2 turtle-shaped objects in opposite direction. The stone tank and upper turtle's base were carved from single pieces of Tatsuyama stone. These are similar to the carving at the Sakafuneishi ruins which are believed to be a ritual site for Empress Kōgyoku (594-661) in Asuka, Nara Prefecture. Nowadays they are still used for rituals to commemorate ancestors by floating sheets of wood with their names on the water.
