A number of records refer to the origin of the temple, such as the Nihongi and Fusō-ryakuki. The original buildings of what was then called Hōkō-ji were constructed in 588, shortly after the introduction of Buddhism from Baekje, one of the three principal states on the Korean peninsula, according to various sources including Buddhism in Japan.
Following the transfer of the capital from Asuka to Heijō-kyō (now Nara city), the buildings of Asuka-dera were also removed from the original site in Asuka to Nara in 718 CE, and developed into a huge temple under the name of Gangō-ji. The original site of the Hōkō-ji was also maintained as a temple which survives into modern times.
The main object of worship at Asuka-dera is the bronze Great Buddha, which said to be made by Kuratsukuri no Tori in the early seventh century. The statue is a designated an Important Cultural Property.
