《Points I want to emphasize》
A work that draws out the water absorption of roof tiles and the unique qualities of pottery. Currently, sauna stones are mainly made of natural stones or ceramic products that have unique heat
resistance, but I noticed that tiles, which are also used as roofing materials, are suitable in terms of material, so I focused on a new material that had never existed before. Since each one is hand-made, no two are the same, and the design, in which aromatic water collects in the dent of the main body, is also suitable for roryu.
“Concept Theme”
The Sauna Stone, which has a motif of Onigawara, which is unique to tiles, has a variety of facial expressions, so you can enjoy it visually. Onigawara has been popular since ancient times as a “guardian deity” or “talisman” for the home and family, and was made in the hope that it would ward off evil while sweating in the sauna. The oni ball is designed with a phantom ball pattern, and is based on the image of a demon.
《Technology…advanced techniques or techniques used lightly in production》 We have developed a mixture of clay that does not break even with a temperature difference of 385 degrees by mixing heat-resistant materials with ordinary tile clay so that it can be used without problems even in a high-temperature sauna. In addition, the
heat-resistant material is less sticky, making it more difficult to handle than normal tile sticks, and difficult to mold, but it was made with technology.
《Main sales target》
At Kisuke-no-Yu, a hot spring facility in Matsuyama City and Imabari City, the “Onimaru and Onidama” made that year are used for the first Setsubun event in Japan by performing a prayer to ward off evil at the Henjoin temple in Kikuma-cho, Imabari City, which is famous for warding off evil. The event will be held in 2022 to wash away misfortunes with steam in the sauna room using “jabara extract” from Uchiko, where you can pay attention to the aroma water used for the aroma water. The event was a huge success, attracting 40,000 visitors a year.
《Main usage》
Warm it up with a sauna stove and pour aromatic water over it. Also, when not in use, you can decorate it and enjoy looking at it. 《Industry business category for which you want to develop sales channels》 We would like to expand sales to sauna manufacturers, hot bath facilities, and domestic and overseas as a high quality sauna stone made in Japan.
