Archaeological sites that are found after the eruption of a volcano and have objects and people "frozen in time" (the "Pompeii Effect") are not common, and they are usually compared to Pompeii. This is usually taken by media as a catchy phrase everywhere in the world. It is important because of that characteristic, but also because it is rare to find remains of bones in excavations in Japan, mostly because the soil is too acid and makes every organic material dissapear.

The picture is not really good to describe what can be seen, but it seems there is a large bone on the bottom right part of the armor, which could be the femur. So, to have a general image, it looks like he was on his/her knees and falled on his/her back. The yellowish part is the armor. It will be easier to see it when the archaeological report shows the drawings and pictures of the findings.
