This is a tonkori, a traditional stringed instrument of the Ainu people. The tonkori is a long, slender instrument with five strings (occasionally 3-6 strings) traditionally played by the Ainu people of Hokkaido and Sakhalin. It is made by hollowing out wood, and glass beads are placed inside as a symbol of the "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 by plucking the strings with the fingers. This is a work by Tonkori Kobo Inonno in Naganuma. The maker was originally a furniture craftsman, so the craftsmanship is meticulous. The carvings are also delicate. It seems the artist has a two-year waiting list for orders. It is made of old Japanese cedar wood and has carvings all over the surface. The carvings are also magnificent. This is the next item to be listed, and it is said to be the 99th and 100th twin tonkori from Tonkori Kobo Inonno. Shamisen strings are used. The strings are numbered 1, 2, 3, 4, and 5 from right to left. 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. It is painted and has carvings of Ainu patterns on the body. 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.
