Ryojinseki (Saitama Prefecture) [Famous Japanese Stones]

Ryokami stone

Ryoshin Stone

Mount Ryokami, one of the three Chichibu mountains, has been an object of worship since ancient times.
There are several theories about the origin of the name, including one that it is named after the two gods Izanagi and Izanami, and another that it is called "Dragon God Mountain" because the dragon god lives there, but either way, it is clear that it is a mountain where gods live.
The rocks of Mt. Ryokami are very hard and are known as a mountain composed mainly of chert.
Chert is formed by the accumulation of fossils such as radiolarians, indicating that this area was once a sea.
