Hayashi Kensetsu Kogyo Group
Black stone spa SAKURA (sapporo Japan)
under the direct management of Hayashi Kensetsu Kogyo CO., Ltd.
● We collect black silica from the lofty mountains of Kaminokuni-machi, Hokkaido.
It is a natural ore formed from diatomaceous sediments 6 billion years
ago, and it is academically called ‘graphite silica stone’. It is commonly
known as ‘silica black’ or ’black silica’
● There are various natural ores available to the makers of stone-slab baths, but the black silica has exclusively high emission rates of far infrared rays. The rate is remarkably 98%.
● And it performs maximum emission rates at 39.9’C,
so it should be the most fitting
combination for the stone-slab bath.
● Every living organism, including human beings, consists of water. 70% of human body is water.
● The water molecules compound clusters, and the impurities, such as body wastes, are trapped in between them.
● The clusters split, by the resonance absorption phenomenon, when irradiating 4-14 micron of far infrared rays, and the trapped impurities can be discharged from one's body then.
● This 4-14 micron range rays are called ‘vital-rays’. Without these rays, there was no birth of living orgasm on the earth. Black-silica radiates the ‘vital-rays’ at normal temperatures. (39.9’C)
