Types of Soil Used by the JIA as Yamashita Treasure Sign

The most common method on how the JIA (Japanese Imperial Army) hid their war loots during WW2 (World War II) were “burying them deep under the ground”. According to some historical reports, the JIA even utilized their slaves where they carried the treasures and dug tunnels for them. The most “inexcusable act” committed by the JIA particularly their high-ranking military officials was they killed all those who witnessed the locations of their hidden treasures. So aside from the slaves, they also murdered most of their men before they finally surrendered to the Allied Forces.

So how exactly did the JIA buried treasures in Philippines?

1. The Treasure Deposit

After digging a certain amount of depth from the ground, they usually create a “chamber” at the end where they store the treasure deposits. This is often the case for large hidden Yamashita deposits.

One of the most common question asked about depth is, “How true is 45 feet deep on Yamashita treasure?”

Based on my experiences, small buried deposits usually consists of shallow depths ranging from 1 to 5 feet only. Yamashita treasure found at medium deposits goes around 10 to 15 feet depth while large deposits ranges between 60 to 120 feet deep.

The 45 feet deep rule actually came from a successful treasure hunter who recovered one deposit at this particular depth. Just because he was able to uncover the deposit at this depth, many derive into a conclusion that majority of the deposits are also buried at 45 feet deep.

2. Dangerous Traps

Once they piled all the treasure deposits inside the chamber, “booby traps” were setup which gets automatically triggered when any of the items are moved or disturbed. Aside from booby traps, the JIA also used poisonous gas and chemicals as deadly traps.

3. Hard and Thick Concrete

Next to the chamber can be a hard and thick concrete that will not easily break. Some THs call it as the “Japanese Treasure Seal”.

4. Human Sacrifice

Unfortunately, the slaves who worked in burying the treasures were not spared by the JIA. They were shot to their deaths usually after “halfway-through” of covering the hole before the Japanese soldiers took over in filling up the rest. This explains why some THs are able to recover human remains or skeletons on their diggings.

5. Clams and Sea Shells

Clams and sea shells are commonly used buried treasure signs by the JIA. Since it is common to encounter these objects especially deep under the ground, THs must try to distinguish them if they are “actual signs” or just natural. When used as an actual sign, the clams or sea shells are well arranged in some strange manner.

These clams and shells are often encountered as treasure sign either along with the human skeletal remains or after it. On some rare cases, they were also placed on the “final layer” which is near the deposit.

6. Pebbles or River Rocks

The JIA also used pebbles and river rocks as buried treasure signs particularly on deposits hidden on dry places. These objects are often encountered by most THs before the clams, sea shells or human skeletons.

Any curious individuals who discover rocks or pebbles that originally belong to the river on a dry land will surely “draw curiosity” about their existence. Anyone can realize that somebody must have brought them on that particular place for some certain purpose. As for experienced THs, they can easily conclude that these objects are “treasure signs”.

To distinguish pebbles and river rocks, they usually have smooth surfaces and a lot tougher to break as compared to the rocks found on dry lands.

7. Bottles

Bottles are also another common treasure signs used by the JIA. Most THs encounter these objects at a depth of around 3 to 10 feet deep. Although, THs must examine the bottles they found and try to distinguish if they are old or new. Distinguishing old bottles from the new is actually easy. New bottles have clear, fine and smoother surfaces as compared to old bottles which were roughly made.

The common colors of old bottles used by the JIA as buried treasure signs are dark-brown, brown, dark-green, green, dark-red/maroon, blue and clear/colorless.

8. Ammunitions

On some deposited sites, the JIA also used ammunitions as buried treasure signs. They are usually encountered by many THs at shallow depths ranging from “12 inches to 3 feet deep”. However, some of the Japanese soldiers were clever enough to scatter them all over the surface area of the deposit’s burial site. This tends to confuse most THs with EMDs (Electronic Metal Detectors) due to these scattered pieces of metallic objects.

9. Different Types of Soils

And finally, the JIA also utilized different types of soils as treasure signs. Let us have a further discussion about this topic below.

Different Types of Soil as Japanese Treasure Signs

Soil found in the Philippines consists of several different colors. Due to these varied colors of the soil, the JIA came out with a good idea to utilize them as treasure signs.

Here are the following different colors of soil found in the Philippines:

a. Brown
b. Black
c. Grey
d. Red or Orange
e. White
f. Yellow
g. Violet
h. Pink

So how the JIA used these varied colors of soils as treasure signs?

Back in WW2 specifically during the “near defeat” of the JIA, the Japanese soldiers ends up digging a lot of holes, pits and tunnels which served as their “underground hideouts”. Thus, most treasure burials sites consists of many other dug holes nearby. And due to this, they had access to different properties of soil.

Depending on the availability of the different colors of soil they found, they filled the hole with treasure deposit in a manner of “alternate layers” of soils they acquired. There is actually “no standard order of colors” they followed. However, the final or surface layer is always the original type of soil they dug from the ground of their treasure’s burial spot.

At some point, the JIA often contaminated the inner layers of soil with deadly chemical poison. If a certain individual got exposed into this chemical poison either by “skin contact” or “prolonged inhalation”, the victim will experience itchiness then dizziness. Later effects are paralysis and then death. Many diggers had already fallen victims into this deadly poison and unfortunately they died because there is “no cure”.

Moreover, THs who are aware about this clever method by the JIA in utilizing different properties of soil as treasure signs can confidently confirm that they are digging on the correct spot. Thus, the need for EMDs or Dowsing tools may no longer be necessary.

      Hi Sir! May I ask the meaning of a piled soil consisting of 3m diameter and 1m high with a lot of stones arranged like a crown on top of it? Nearby is a medium size rock having a shape like a pointer. It is pointing towards the old bamboo trees which is situated near the creek (20m away).

      My father dug the spot of the piled soil and he did not found anything.

      According to our forefathers, the site was a Japanese military garrison back in WW2. Sir, can you give me your own idea about this? Thanks.


      That piled soil is strange which makes it obviously a sign. If your father dug it then I wanted to know how deep did he reached before he decided to stop. Anyway, the rock which seem to be a pointer is another interesting sign. Since it is directly pointing towards the old bamboos then I recommended checking that portion for some clues.

    • Hi Sir, we dig in the center of the three triangle Japanese bamboo and found piled rock. At the center is a stone engrave with heart sign and the other side with Japanese letters.

      • That is an interesting site. The heart sign simply represents a very valuable deposit on that area. As for those Japanese letters, you need to take a photo and send it or PM it to my FaceBook Page.

          Hi Sir Elmo. I just want to ask a question. We've been digging 3 meters then after that we've found boots and a shell. What does it mean Sir?

          • The boots along with the shell that you found are objects confirming that you are digging on the right spot. Thus, it basically means that you just continue digging.

        • Sir good day. Update regarding the three Japanese bamboo tree. Under the bamboo is a square flat stone, we accidentally break it then under the second tree 1 meter, we dug a turtle stone having head only with grove.

          • Nice, keep it up. Just keep going.

    • Good day!

      Many have already tried to spiritually pin pointed that there is something buried right under the house of my friend. Other than that, there are two old Japanese guys who mentioned themselves that there really are treasures in there. So we borrowed a metal detector and used it on the area which also confirms it.

      We started digging and reached already 12 ft and we hit the water trap. We also uncovered human skeletons. However, we stop our operation since the last day where during the night, we heard loud noises coming from the site where there seems to be other people trying to continue our excavation.

      We tried to seek for spiritual advice and he said that the item was transferred by one of our bad fellow digger. What should we do? Do you know someone with a third eye? Where can we rent a very reliable metal detector?

      Thanks and God bless.

      • You should have went into the site during the night that you heard that loud digging noises. Go along with the whole group and try to catch them on the spot. This actually gives me the feeling that during that night, the item was already recovered while you are left clueless about what just happened. Anyway, if it happens that its not then there is nothing wrong trying to continue your excavation. The human remain is already a good starting sign that you should keep going.

      Sir I am from Cagayan, Luzon. We are almost 8 meters deep and we encountered water. Digging it deeper for 3 meters, the water became oily. What does it mean? Please reply back Sir.


      You need to distinguish if the oil is natural or not. Anyway, may I know that signs why you dug on that spot?

      We continued working by digging down on our project which I think is a pit or sealed tunnel. We are now at 15 feet deep where we managed to remove the layer of sand gravel and cement. Now, we encountered a circular concrete flooring measuring 2 ½ feet in diameter. It has a small hole at the center filled with gravel and cement.

      By the way Sir, the hard layer is just an inch of thickness. What shall we do next? Thank you and God Bless.


      Try to uncover that circular concrete with a hole at its center. I wanted to know its thickness.

      Good evening Sir Elmo. For about 13 feet deep, we found 4 big clam shells measuring almost 3 feet in length. Is it possible that these clams have hidden deposit inside them? We also discovered a tunnel inside measuring 15 feet diameter opening. Although, some openings only have 5 diameter sizes.

      The hole that we are digging consists of soil, sand (very fine like white sugar) and a very sticky soil. Upon excavating it, we found a big stone standing up with an estimated weight of about 100 kilos.

      Are all our findings good? By the way, out site is near the sea.


      Yes, it is possible that there is something hidden inside those big four clams especially when they are heavy. The tunnel that you discovered are also interesting which requires further exploration. I think one of those pathways will lead you into the chamber and there are probably signs around the corners that you have not noticed yet telling the correct path to take.

      Good day Sir Elmo. I am from Mindanao and we have a product that we dug for about 35 meters. At this depth, we encountered a purely hardened steel rock but we managed to break it and continued with our diggings. It was followed by a layer of soil with sands. The color of the soil was pink and the layer consist of about 3 meters thick. Unfortunately, water suddenly came out so we used two water pumps with 3 Hp.

      In your own opinion, what is the next layer after the pink soil? Thank you and I hope to hear from you. God Bless.


      I cannot guarantee that you site is positive unless you can give me the details of the signs that you found prior to digging it. Anyway, the deposit is usually near the trap. In your case, you triggered the water trap.

      Sir good day. What is the meaning of a red color sand? I dug this layer at about 4 feet deep. Another question that I would like to ask is, how thick is the JIA treasure seal?


      As stated on the post above, it is a sign that simply indicate that you are digging on the correct spot. As for your second question, it ranges between 1 to 5 feet.

      Hi Sir. We dug underneath a strange yellow bamboo and at 5 feet deep, we found a straight wall going down. When we penetrated through the wall, we encountered piled rocks. Then at 10 feet, water suddenly came out from the bottom so we used water pump. We noticed that the color of the water is chocolate brown. What does it mean?

      The most interesting sign that we found was a broken glass and a bolo which we recovered at 3 feet deep.

      I want to send you the photos of the wall. How can I send it to you?

      Please help me analyze out site because I know that you are an expert on this field.


      Most importantly, does the water makes your skin itchy? If it does then it is contaminated with poison where you must avoid being exposed.

      The signs that you discovered are also interesting and I would love to check the photos that you got. Please send them into my FaceBook page.

      Dear Sir, I have been digging in an area consisting of piled rocks with different sizes. The later of the soil from the top is 2 feet then followed by 6 inches of 0.5 inch stones then at the deeper portion were large boulder of rocks. Right now, I stopped digging because it is very dangerous. The further that I dig deeper especially removing the rocks, the walls will collapse. My question is this, is this a positive spot?


      It is hard to confirm if your site is positive or not unless you can find a certain authentic sign. A piled rock does look strange but it is not good enough to conclude that the spot is positive.

    • Sir Elmo good day. We are already more or less 15 meters underground and have found different signs made of cement and some broken parts of woods until we reach 4 concrete fence-like signs made of concrete about 1 foot in height with one of them reddish in color. What do these signs mean sir Elmo?

      Thanks and God bless you always.

    • They are still "layer signs" as discussed on this post.

      Good day sir! I just want to ask, did the Japanese use magnetic rocks? I mean, we are already in 40 ft underground and there are large rocks that are magnetic. What does this rocks mean? thank you so much in advance sir!

    • If these magnetic rocks are not so common around then it can be considered as a sign.
