This fort was one of many in a network of fortifications used by the Koide Clan. See Ina Koide Castle for more information.
The most salient remains of Arajō is a karabori (dry moat) remnant protecting what was once the fort's inner sanctum, which is now a rice paddy. Most of the moat has been filled in for the paddy and the remaining portion quickly descends as a tatebori (climbing moat). It's something at least. As for other remains I think I identified terracing of the hill side and former baileys, but it was hard going.
