Please be sure to read the profile before purchasing. This is Yakushi Stone from Murasugi Onsen in 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 groundwater passes through the Yakushi Stone of Mt. Gozu, becoming hot spring water containing radium. There are two stones in total. After collection, they have been washed and dried in the sun. They are rare semi-granite stones, and some have a bit of standard and pegmatite mixed in with the semi-granite. They contain trace amounts of radiation. These are genuine products, and I used a Geiger counter to measure alpha, beta, and gamma rays during collection. In my opinion, it's best to use them in the bath. Fill the bath with water the day before you want to use it, and put the stones in. Close the bath lid 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 doing proper maintenance. I went collecting recently. I expanded the survey area and went deeper 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 we can 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.
