There are some 300 Japanese tunnels and caves on the island of Iwo Jima. ONLY 5 of these 300 tunnels are deemed “safe”, and visitors are ONLY allowed to enter and explore these five “safe” tunnels and caves. The other 297 tunnels and caves are off-limits. The risk of cave-ins, affixation, and undetected booby traps being too high to allow visitors to enter. During our 72 hours on the island, we the BATTLE RATS found and explored 54 different Japanese tunnels. Each of which were marked with GPS waypoints. I would like it known that while we did at times take chances and risks, we did exude a certain degree of caution and were not foolhardy in our tunnel explorations.
