The Hakuseki-kan is a museum of minerals and jewels.
There is a pyramid made with locally produced 5,500 tons of granite. It is reproduced in 1/10 the size of the pyramid of King Khufu, and the underground maze is spreading. You can see rare exhibits such as natural crystals, diamonds, fossils, stone of the pyramid in Egypt, rock of Everest.
The popular corner in the museum is the “jewelry search”. There are 30 types of precious stones and jewels in the sand of the pool, and you can get them by digging with a bowl or hand.
