This is a tonkori, an Ainu stringed instrument. It is a traditional, slender five-stringed (rarely 3-6 strings) instrument of the Ainu people, mainly from Hokkaido and Karafuto (Sakhalin). It is made by hollowing out wood, and glass beads are placed inside as a symbol of "soul" to produce a good sound, with the parts of the instrument likened to the human body. It is a traditional instrument in Ainu culture, played using an open-string method that creates tones with only five notes, plucked with the fingers. The strings of a shamisen are strung on it. From right to left, the strings are 1, 2, 3, 4, and 5. Please tune it to D, G, D, A, and E, as tuned by Ume Nishihira. Strings 1 and 3 are one octave higher than the others. We also have Ainu clothing, costumes, crafts, experience kits, and old Ainu folk tools for sale, so please take a look if you are interested.
