Field Notes

Iwakura-yakata is a yakata (fortified manor hall) ruin in Iwakura Township. It is built on a ridge terminus beneath the Iwakura castle-mount, and consists of a bailey with a large trench complex to the rear. The horikiri (trench) is impressive, and it is spanned by a dobashi (earthen bridge). Dorui (earthen ramparts) are heaped up on the inside of the trench. The bailey is on private property and a fence has been erected on the dorui. Whilst most dorui in the past would've had stockades and abbattis atop, it's not common to find dorui used to host a modern fence!

I accessed this site by descending from Iwakurajō down a strip of earth which had been left standing between what looked like landslides. It also appears that the mountainside here might've been used as a stone quarry. It seemed like there were some earthworks and flattened spaces just above the yakata, but they did not give a clear impression.
