Isshiki Castle (Suruga)

History

Isshikkijō is subject to much speculation but nothing is known for sure. Its history seems tied to that of nearby Nagakubojō (Nagakubo Castle), though whether it was built as a satellite fortification of that castle or as a fort to besiege it is unknown. It is said the castle was first built by the Hayashi Clan, vassals of the Imagawa Clan, and was later used by Toyotomi forces during the Odawara campaign.

Visit Notes

Isshikkijō of Suruga Province is an earthworks fort ruin situated on a small plateau. Ruins include dorui (earthen ramparts) and a karabori (dry moat), and these can be seen from the rear of the site where there is a footpath. I get nervous whenever there is a footpath in a karabori because one wonders if it isn’t some subsequent cutting to create a pass, but the karabori continues and becomes a tatebori (falling moat) even as the path turns off around a bend. The bailey above is surrounded by dorui. I could see that by poking my head in from the koguchi (gate site), but one cannot actually enter the bailey itself as it is private property used as farmland.
