It is the third book of the four mirror series. It deals with the oldest time-period, starting with the legendary Emperor Jimmu and ending with Emperor Ninmyō. It is told by a fictitious old woman who is visited by a bhikkhu while staying at Hase-dera. All the facts are taken from ca. 1150 by Kōen, the teacher of Hōnen. "Mizukagami" refers to the reflective pool in Japanese gardens in which can be seen such things as bridges and cherry blossoms in its reflection.
