KubodonoYashiki (3).JPG


Kubodono-yashiki was the fortified residence of the Kubo Clan. The Kubo Clan served the Aida Clan and helped protect the Aida Valley from this its outer opening. The yashiki (residence) site is at a confluence, indeed, of the Aida and Sai rivers. It is thought that the Kubo Caln also fortified and maintained Koyajō on the nearby ridge, which would make their yashiki the kyokan (residence site twinned with a yamajiro (mountaintop castle)) of Koyajō, though it is said that Koyajō was originally built by the Tōhara Clan.

Visit Notes

Kubodono-yashiki is a medieval residence site. Not much remains in terms of ruins, but the terrain which overlooks a confluence of rivers seems readily fortifiable. There is a depression to the east called 'moat-field', which is the site of a moat, and supposedly there was another such moat wrapping around the residence area in the east, but this is now a depot for municipal vehicles. Some castle bloggers have found old mounds which are possibly dorui (earthen ramparts) but I did not find these. I was using a map produced by Teipisu-sensei in 2008 as a guide, but the site has been further developed since then and I could not get to the rear of the site where the dorui would be. There is a municipal office on site and there has even been a new house built in its carpark. Who builds their house in a carpark? Modern houses pop up in disorderly fashion like weeds amidst fields and old homesteads in Japan's dwindling countryside.
