The Bizen Kokubun-ji temple site is located in the Umaya neighborhood of the city Akaiwa, on an
alluvial fan between the
Yoshii River and the Asahi River. The route of the ancient
San'yōdō highway runs through the southern part of the temple grounds. Currently, Kokubunji Hachimangū Shrine is located in the center of the western portion of the former temple grounds. The temple's location was confirmed by an
archaeological excavation in 1974, when the site was slated for development as a housing estate. Further excavation were conducted in the year 2003. During these excavations, the foundations of the South gate, Middle gate,
Kondō, Lecture Hall, and priest's quarters were found to be aligned in a straight line from south to north within a 175 meters (east-to-west) by 190 meters (north-to-south) walled compound. The South gate and the Middle gate were situated very close to each other, which is an unusual layout of the temple. The actual foundation date for this temple is uncertain, but it believed to have been built around the time of the imperial edict for the construction of the
kokubunji temples in 741. Its name appears in the early
Heian period Engishiki records, and it is believed that renovations were made in the 10th century, but that the Lecture Hall and northern portion of the
cloister was destroyed by a fire around the mid- to late-12th century. It is presumed that the pagoda and perhaps even the Main Hall were also lost around this time. Archaeological evidence suggests that a new Main Hall was constructed in the northeastern corner of the original Lecture Hall site in the early
Kamakura period. A seven-story stone pagoda that is believed to have been built in the early
Kamakura period still stands on the site of the original Nara-period pagoda. By the
Edo Period, the site had disappeared under
paddy fields, and a nearby temple called Enjū-ji claimed to be the successor of the Bizen Kokubun-ji. It connection with the ancient
kokubunji, if any is unknown. A large number of
roof tiles from various eras, and shards of Nara
Sancai pottery have been excavated from the site. The site is now an
archaeological park, where visitors can see the foundations of the Nara-period buildings. Nearby is the
Ryōgūzan Kofun, which has a separate National Historic Site designation. The site of the Bizen
kokufu is located about 6.5 kilometers southwest.
