Sanjusangen-do, as a National Treasure, is a Buddhist temple in Higashiyama ward of Kyoto city. The official name of the building is Rengeo-in Temple and the main hall is called as Sanjusangen-do. It comes from that there are 33 units between the pillars in the inner sanctum. The number of 33 is based on 33 incarnations of Bodhisattva Kannon.
In the late Heian Period, Emperor Shirakawa, who initiated the system of cloistered rule, built the Hojuji-dono Palace, and Sanjusangen-do was built inside afterward, with the financial sponsor from Taira no Kiyomori, who got power during the time. However, it was destroyed by fire in 1249 of the Kencho Period, and only the main hall was rebuilt later. It is said that the outer walls were painted with red lacquer and inside the hall was decorated with full colors. The roof of the main hall, which is 16m tall, 22m deep, and 120m long from south to north, incorporated the hip-and-gable roof style and tile-roofing style to create the pleasant view of a straight line. In addition, the seated statues of Thousand Armed Kannon is placed in the hall center, and Life-sized 1000 standing statues of Thousand Armed Kannon are arranged around it, which is very magnificent. It is said that one can definitely find a statue that resembles the person whom he want to meet among those statues of Kannon.
