The temple was just destroyed by flooding and a lot of its goods were lost. All that was saved, including a precious statue of Kannon sculpted by Kobo Daishi, were brought to the new location, in a small village called Hiokimura.
The presence of the temple raised the importance of the village, and as a result the name of the place was changed to Ōsu, as the original location of the temple. Today, the official name of the temple is Kitanosan Shinpuku-ji Hosho-in, but it is know as the Ōsu Kannon Temple.
