[1] The National Historic Site designation encompasses three discontinuous but related areas within Kamiichi at the foot of Mount Tateyama which contain the ruins of a Buddhist temple, a cemetery, and a sutra mound built from the end of the Heian period through the Kamakura period, which are noteworthy both for their size but also for the quality of excavated items.

The sites are located about 15 minutes by car from Kamiichi Station on the Toyama Chiho Railway Main Line; however, there are no public facilities.

The sutra containers include Suzu ware and ceramics imported from China during the early Kamakura period and also include a number of Shingon Buddhism ritual implements from the late Heian through Kamakura periods.

The temple of Shingō-ji (真興寺跡) is mentioned in historical records, but its exact location is not documented.

This site was found to contain the foundations of monumental gate, pagoda, Hondō and a pond in a configuration which is in accord with what is known of the Shingon-sect temple of Shingō-ji in historical records.
