Other than the above two areas, there is an area called 'Ebinoko-kaku' (Ebinoko enclosure) (so named because it was located in the subsection of the village called 'Ebinoko'), where the large hottate building (called the Ebinoko grand palace) measuring 29.2 meters by 15.3 meters and the canopies on four sides were discovered.
この他に、「エビノコ郭」（小字「エビノコ」にあることからこの名にしている）と呼ばれる一画があり、29.2×15.3メートルで四面ひさし付きの大型の掘立建物（エビノコ大殿と名付けられている）が発見されている。
