The Akayama Underground Fortification in Tateyama City is a large-scale underground fortification stretching 1.6km in length. The interior is like a maze, allowing you to experience the feeling of exploration. One of the attractions is the beautiful layers of earth where the feelings of the people of that time are engraved. It is not only a war heritage site, but also a precious place called the Kagamigaura Formation. The dim and cool interior is like a completely different world. Why not visit at least once and experience it for yourself?
