Aratoshōjō was built as a satellite fortification of Aratojō (Arato Castle); it means "Arato Lesser Castle".
Aratoshōjō is a single bailey fort and fortified annex of Aratojō. The main bailey is twenty metres at its widest and fifty metres long. It’s most prominent remains consist of a row of dorui (earthen ramparts) along the northern perimetre of the bailey. It’s quite remarkable that such dorui remains relatively thick and tall here. There is no dorui on the south side. Perhaps it would’ve been more important to protect the north since that faced away from the Yamada Clan’s territory, but I also note that a modern forestry road runs beneath this bailey on the south side, and so it may be that part of the bailey was demolished to construct the road.
