The presence of abandoned Japanese tunnels in many parts of the country also became urban legends and telltales about haunted places, the Yamashita treasure and the interests of some treasure hunters, and many chilling stories of death and suffering told across generations.

During the Second World War, the Japanese imperial army bore tunnels using manual and hard labor involving Filipino prisoners of war and Japanese conscripts. The tunnels served as a hideout for Japanese soldiers to escape the eyes of American and Filipino soldiers. It was also a way for their covert operations.

The Japanese tunnels offer a unique experience to intrepid travelers who enjoy adventures and explorations. This was designed like a network of branching and intersecting tunnels. In the middle part of the tunnel, you can find a water-filed well.
