Yakushi-ji Temple is located in Nishinokyo in Nara City, Nara Prefecture, and one of two head temples of the Hossou religious sect. The principal image of Buddha is Yakushinyorai. Yakushi-ji Temple is the first temple of the Yakushi Pilgrimage of 49 Temples in Western Japan.  The temple is also one of the Seven Great Temples of Nara.  It was built by the Emperor Tenmu in 680.
Tou-tou or the East Pagoda, towering inside the temple complex, is 33.6m in height. The pagoda is believed to have been renovated in 730 to make it a good counterpart to the West Pagoda.   This was done when the capital was relocated to Heijyou-kyo and the whole temple was moved to the capital. The East Pagoda has been designated as a National Treasure.  The most notable feature of the East Pagoda is that, although it has three stories, its three additional lean-to roofs called mokoshi, make it look as if it has six stories. On the upper part of the tower, there is an openwork ornament called Suien (the Water Flame). There 24 heavenly beings were carved, some of which are playing flutes or planting flower seeds and some offering prayers.  Suien is a charm to protect the pagoda from fire.
The East Pagoda of Yakushi-ji Temple is the only structure that has survived intact for a very long period of time, since the original foundation of the temple.
