They are a gift from the super-ancient past, captivating with their mystical charm. Stone flutes are also called "iwabue" and have been revered as sacred objects, "monozane," used to summon the gods in several Shinto sects. Since they have been excavated from Jomon period ruins, stone flutes are also known as the "sound of the Jomon period." You can obtain a high-pitched, clear tone by blowing the stone flute in the same way as playing a shakuhachi flute or by blowing into an empty bottle. 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.
