Please be sure to read the profile before purchasing. This is Yakushi Stone from Murasugi Onsen, Niigata Prefecture. Murasugi Onsen is a hot spring resort boasting high concentrations of radium, said to be one of Japan's top 3 or 5 hot springs. It is said that the underground water passes through the Yakushi Stone of Mt. Gozu, becoming hot spring water containing radium. There are two stones in total. After collection, they are washed and dried in the sun. One is a standard stone, and the other is a rare semi-granite with pegmatite. They contain trace amounts of radiation. These are genuine products, and I used a Geiger counter to measure α, β, and γ rays during collection. In my opinion, it is best to use them in the bath. Fill the bath with water the day before you take a bath and put the stones in. Close the lid of the bath and leave it overnight, then just heat the bath the next day. I think it will warm you up more than using bath additives. Maintenance is simply washing the stones and drying them in the sun once a week. You can use them forever just by maintaining them properly. I went to collect them the other day. I expanded the survey area and went further into the mountains, where I found stones with significant metamorphic effects. In a survey four years ago, I also found pegmatite in the same layer and brought back a sample. I plan to take this to a research institution in the future, and I believe it will be possible to identify rare earth minerals. Because it contains rare earth minerals, the radiation level is also high, and I have high expectations for the future. We also offer comprehensive after-sales support.
