【war-related site】Underground Bunker Cluster of Futaegoshi

The cluster of underground bunkers at Futaegoshi are constructed by digging into the eastern side of the hills. The cluster is formed by ten bunkers and the largest is connected by five openings, with a total length of over 200 meters. Among the bunkers, there are those constructed with concrete, and those with iron hooks and insulator in the interior, believed to have been placed to lay electric wiring. These finds tell us that this cluster of bunkers played an important role in military operations. From interviews and relevant documents and records, it is believed that this was the headquarters for the Navy Guards.
