Totsui shonyudo (Totsui Limestone Cave) is named after the small harbour village Totsui where it is located. This cave has a natural entrance and has been known since ancient times. Until 1945 the area has been used as a limestone quarry and so parts of the cave have been destroyed. The limestone outcrop is called Chichibu Belt and consists of Jurassic and Cretaceous limestones. It is enclosed by Silurian and Permian crystalline rocks, mostly granites.
Because of the long time the cave was visited by man and the time as a quarry the cave has little speleothems. The stalactites have started to grow again, but there are only small beginnings of soda straws. The main feature of the cave is the iteresting gelogy, of a cave in an isolated outcrop of limestone in the middle of crystalline rocks. Also the ceiling shows interestig structures caused by the chemical dissolution of the limestone. Minmal difference in the chemistry caused the cration of honeycombed structures which are called beehives or sponge work.
