A few meters beyond the third Torii (San no Torii), where the western bridge goes over the pond leading to Hachimangu, there is a stone historical marker that states:
According to the Azuma Kagami, in April 1182, Minamoto no Yoritomo allowed Senkōbō and Ōba Kageyoshi to dig a pond at the Hachiman Shrine. So it is written. Another theory is that Masako, Yoritomo's wife, built this pond for the hope of a thriving Genji (an alternative name for the Minamoto clan) and planted a white lotus in the east pond and a red lotus in the west pond. It is said to have displayed the color of Genpei's flag, therefore it is named Genpei Pond.
