The door paintings remain from the time of the temple's founding but, the front middle doors were replaced when repairs were made in 1670 during the Edo period as these two pieces were the most severely worn and they are therefore given an 'additional designation' not included in the 14 pieces that have been designated National Treasures.
扉絵は創建当初のものであるが、正面中央の2面の扉は、もっとも消耗が激しかったためか、江戸時代の寛文10年（1670年）の修理の際に取りかえた新しい扉になっており、国宝の14面には含まれない「附（つけたり）指定」となっている。
