Nyorai (如 来) refers to the Buddhas, ie those who have attained enlightenment. The word Nyorai comes from the Sanskrit Tathagata, which Buddha used to designate himself.

Originally Nyorai was used only for the original Buddha and then for all those who reached enlightenment.
During the pilgrimage of the 88 temples, five Nyorai are represented. They are part of the thirteen Buddhas ( Jūsanbutsu – 十三仏 ).
