History & haunting lore

The Matsushiro underground headquarters is a strong Japan addition because it is both physically atmospheric and historically serious. Tunnels, forced labour, and late-war secrecy give it a heavy presence. Use public tunnel sections only and keep closed areas closed.

Current site status

Public sections exist, but closed tunnels are hazardous. Follow signage and access rules.
