The colored paintings on the internal four pillars, hinuki (a neck penetrating tie beam which extends through a pillar) on the upper part of the pillars, and the ceiling are greatly damaged by peeling and falling, but nevertheless they are a valuable legacy from the Nara period painting and designated as important cultural properties as 'paintings' separately from the architecture.
内部の4本の柱と上部の飛貫（ひぬき）、天井の彩色絵画は剥落が甚だしいとはいえ、奈良時代絵画の遺品として貴重なもので、建物とは別個に「絵画」として重要文化財に指定されている。
