This article works on the development process of the Buddhist Temple with two pagodas in the Eastern Asia. in 7-8th centuries. This study was motivated from the observation that why there are many the Buddhist Temple having two pagodas only around the late 7th century, roughly around 670 A.D.. This period corresponds to the Silla Dynasty(in Korean History) and Hakuho Period(in Japan History) among the Eastern Asia while the composition of the temple being changed as Buddhism spreads out from China. The results of this study are the followings. The appearance of the Buddhist Temple having two pagodas was resulted from the representation of the Ideology in Botabpum(dogma of pagoda security) of the Saddharmapundarika Sutra, that is to say, two Buddhas sit side by side and iconography of Esoteric Buddhism dogma supports the spirit for defending one's country. Buddhist Temple having two pagodas in China had separate tab-won(areas with pagodas outer temple building block). Buddhist Temple having two pagodas in Korea had begun with sacheunwangsa temple in Unified-Silla. But it had two pagodas with inner temple area instead of outer. This was different from the composition of China. It can be related to the layout of the temple haying two pagodas in East-Jin(in China History) and the sculpture of two pagodas in Ungang-stonecave(in China). Thus the layout of the Buddhist Temple having two pagodas in Silla had been originated from that of China, but was developed to the main temple layout on her own accord. As Japanese Temple having two pagodas had been influenced diplomatically, it had two pagodas inner area as like the layout in Shilla. But later under the influence of Tang it was modified to the layout having them in separate area. And this influence can be seen for example Tangchojaesa temple. For the more, We call see that the diplomatic trends according to the policies in East asia affected to Buddhism and then naturally also to the layout of the Buddhist Temple.
