The caves of Hundred Caves of Yoshimi
Hundred Caves of Yoshimi is a cluster of ancient grave caves dug on the cliff.
It is located about 2 km east of Higashi-Matsuyama city and in Yoshimi town.
And it is located about 25 km northwest of Omiya in Saitama city.
In Japanese, it is called "Yoshimi-Hyakuana" or "Yoshimi-Hyakketsu".
The name of the place is "Hundred caves", but there are 219 caves on the cliff.
The size of each cave is about 1 meter and all of them were constructed artificially.
It is said that they were made in the 6th and 7th centuries.
But, it is not known why these had been constructed.
Because the ruin of burial chamber was found in the caves, some archaeologists say they were the ancient tombs.
But the other archaeologists say it was the dwelling site of small people in folklore of the Ainu (one of indigenous peoples in Japan).
In some caves, luminous mosses grow naturally, and it is be designated as a national natural treasure.
