The mukkuri is a traditional Japanese musical instrument, often classified as a type of jaw harp. It is made from a flexible metal or bamboo frame with a vibrating tongue that produces sound when plucked. The player holds the instrument against their mouth, using their breath and mouth shape to modify the sound, creating a unique and resonant tone. Mukkuri is commonly associated with the indigenous Ainu people of Hokkaido, Japan. It is often used in cultural performances and rituals, reflecting the Ainu's rich heritage and connection to nature. The instrument has gained interest beyond its traditional context, appealing to musicians and enthusiasts worldwide.
