They are gifts from the ultra-ancient past, striking the heart with their mystical flavor. Stone flutes are also called "Iwa-bue" and have been revered as sacred "monozane" (objects used to attract deities) in several schools of Shinto. Since they have been excavated from Jomon period ruins, stone flutes are also known as the "sound of Jomon." By blowing a stone flute in the same way as a shakuhachi flute or by blowing into an empty bottle, you can obtain a clear, high-pitched tone. Experiment with the thickness, strength, and direction of your breath to create the grand sound of the stone flute. The sound of the stone flute is said to ward off evil and bring good fortune since ancient times.
