History
Suishōzan-jin was one of the jinsho used in the 1575 siege of Iwamura Castle by Oda forces. Given the terrain, it was likely used primarily as a place to observe the besieged castle and to keep watch over its mountainside rear.

Field Notes
Suishōzan-jin is a mountaintop jinsho (encampment) ruin in Iwamura Township of Ena Municipality. Ruins are earthworks such as horikiri (trenches) and dorui (earthen ramparts). The fort has upper and lower sections. The upper section is on the peak of Mount Suishō, and the lower is on the ridge, close to Iwamurajō. The lower jinsho has a some flattened areas and a prominent rear trench. And old mountain path ascends from below and it has berms either side, giving the impression of a gate site where it terminates in the jinsho's bailey.
There are some indications of terracing and earthen bulwarks between the lower and upper jinsho sections. The upper jinsho contains the flattened peak with a long but shallow trench and earthen parapet below. It seems to have been used chiefly as a look-out.
