This ore, classified as a conglomerate, is well known for emitting terahertz waves (cultivation waves), a far-infrared ray. This ore has gained an excellent reputation since being used in the first hot stone spa in Japan. The range of application for this ore is being expanded to the likes of bedrock baths, as it is sturdy and durable of ores for host stone spas.

According to folklore, heating a woman's body with this stone will improve her health, and ensure healthy babies and a safe childbirth. This lava stone contains few grikes (holes) and features a beautiful matt texture with a blue-gray color tone.

The black silica mined in Hokkaido has been proven in water clarification and public projects. It has also been proven in many hot stone spa installations, mainly in Northern Japan. Crushed stone and cement resin are mixed to produce the bedrock for hot stone spas.

The unique structure in which lenticular black silica intrudes into the lava (pyroxene rhyolite) means that the far-infrared effect is enhanced. This is a special ore with excellent efficacy, durability, and texture.
