The Yamashita Treasure is a multi-sided topic. It has in it military, cultural, political, moral, values, religion, science and technology. Say for example, I admire the Japanese for their advancement in Science and Technology, the Japanese tunnels were planted with traps like radioactive materials that readily poison intruders. Back in 1940s, using radioactive matter is a new thing. Also, I am amazed how they constructed deep tunnels in the Phils. knowing the fact that the underground water table in the land is very shallow.
They must be having a water sealant of some sort. I have seen cement made by the Japanese that cant be broken/crack with a hedgehammer.
The Yamashita Treasure is more than just a treasure hunting.
