It is actually a common question to ask about the “average depth of a buried Yamashita treasure” especially for the amateur THs (treasure hunters).
I know that giving an estimate depth in your projects can boosts your motivations but this really requires a lot of analysis by relying to all the clues you found on your site. This is the reason why I often respond to those who are asking estimate depths that “they need to find more signs or clues”.
Honestly, there is no “Average” or “Standard” depth on how the JIA (Japanese Imperial Army) buried their treasures. But based on experience, the depth usually ranges between “3 ft down to 80 ft”.
Reasons Why the Depths of Buried Treasure Varies
There are actually several reasons why the JIA buried their treasures at some random depths.
Here are some of the possible reasons why:
1. Numbers of Soldiers and Slaves
When the Allied Forces (Combined Filipino and American soldiers) finally attacked the JIA, the Japanese army retreated hiding themselves for cover on remote places such as in the dense forest of the mountains. Most of them also got separated from their group. Thus, there were groups consisting of only few soldiers while others consisted more.
Those smaller group most likely hid their treasures at shallow depths because they lack manpower. But as for those larger groups, they were the once who dug extremely deep tunnels and holes. Some even had slaves that helped them dug.
2. Hot Pursuit
The Allied forces were actually in “hot pursuit” against the JIA. Despite the aggressiveness of the Allied Forces, the JIA still refused to surrender because they were given strict orders by their superiors to hid all treasures in their possessions as their primary objectives.
Since the JIA were hardly pursued by the Allied Forces, they do not have enough time to stay on one certain specific location. Due to this reason, they simply dug shallow holes ranging between 3 to 15 feet only. Some of them even simply inserted small pieces of gold bars into the holes of trees or rocks that they passed.
3. Clever Japanese Soldiers
There were some clever JIA soldiers who managed to outsmart the Allied Forces by finding themselves safe hidden shelters. One among them was the Japanese Military General himself, “Gen. Tomoyuki Yamashita“. As a result, they were able to dig deep complicated tunnels for their hidden treasures.
