When you visit Ninna-ji you will likely notice that buildings with tile roofs feature tiles with cherry blossoms like those above. This is because the cherry blossom is the official mark of Ninna-ji. However, that is not the only crest tile that can be seen at the temple.
Due to the monzeki status of the temple and the close relationship to the imperial family, the imperial crest — the chrysanthemum — can also be seen on some buildings on the temple grounds.
Though not a crest, you can find this tile which spells out the temple’s name in Chinese characters on top of the perimeter walls of the temple.
When you visit the temple be sure to look up from time to time to try to catch little details like these!
