The tonkori is a traditional stringed instrument originating from the Ainu people of Japan. It typically features a long, slender body made from wood and has three or four strings, which are usually made from natural materials. The instrument is played by plucking the strings with the fingers, producing a unique, resonant sound that is often associated with Ainu music and culture. Historically, the tonkori was used in various ceremonies and celebrations, serving as a means of storytelling and cultural expression. Today, it is gaining recognition beyond its traditional roots, with musicians incorporating it into contemporary music genres, thus helping to preserve and promote Ainu heritage.
