The date of its founding is unknown. It is said to be the birthplace of Prince Shotoku, and one of the seven temples built by Prince Shotoku in the 8th century. In the 8th century, it was a large temple with 66 halls, arranged in the Shitennoji style. Today, only a few halls remain, including the main hall (Taishiden), which was rebuilt in the Edo period. A seated statue of Prince Shotoku from the Muromachi period (Important Cultural Property) and an attractive statue of Nyoirin Kannon (Goddess of Mercy) can also be seen.

According to temple legend, Oka-dera Temple was founded approximately 1,300 years ago, and was built by monk Gien at the behest of Emperor Tenchi. The name "Ryuugai-ji" is said to have come from the fact that the monk Gien, with his legal power, was able to contain an evil dragon that was destroying the land of Asuka and tormenting the farmers by covering it with a large stone and reforming it.
