Sankouji Fort

History

Sankōji-rui, also called Minamigejō-yashiki, is said to have been the residence of the Ayusawa Clan. It was later the site of the residences of the Iwata and Akiyama clans. These residences may have overlapped, and it's not certain which the ruins left today represent, or which residences encompassed the site of Sankōji temple. The segment of remaining earthen ramparts are thought to have ran for at least 60m in length east-west along the north of the site.

Visit Notes

I found some interesting things at Sankōji, the temple for which this medieval fort site is named, but nothing definitive. The dorui (earthen ramparts) which two high calibre castle bloggers point to appear to have been encroached upon by modern housing. Very new looking houses stand today where a dorui segment is supposed to be. I was able to find an image of some dorui on Google Maps' street-viewer, however, dated 2019. Satellite imagery from 2022 is unclear. If I have this right then there is a surviving clump of dorui but it is very small. I must've missed it. Somebody reported it being 60m long at some point! The site is otherwise modern housing, fields, and the temple Sankōji. I went to temple and was interested in some configurations of mounded earth, now clad in stone retaining walls, which looked like they could've formed some sort of gate complex. I can't confirm any relation to the former fort, but it's possible - to my mind - that it represents some residual remains of the site's southern ramparts.
