The Ganban Koyo Stone, baked for 3 hours at a temperature of about 1300°C, is an excellent Ganban with a high far-infrared radiation rate. Each stone is carefully arranged by the hands of craftsmen, made with sincerity. On the surface of the mat, 465 "Ganban Koyo Stones" developed using high-level technology with a proven track record in commercial use are placed, and "vegetable carbon fiber" that carbonizes the fibers is placed inside. The double far-infrared rays gently warm the body. "Far Infrared Double Thermal" warms the body to the core. The "Ganban Koyo Stone" has excellent heat retention, and the "vegetable carbon fiber" boasts a surface area more than four times that of charcoal. The double far-infrared rays warm the body to the core and increase the body temperature.
