Type: Koto (Japanese harp) Accessories/Parts: Other Level: Advanced This is a masterpiece inherited from the teacher of my mother, who was a master of the Ikuta school of koto. I don't know the details, but it seems these are koto bridges used in older kotos. They are about 5mm to 1cm lower than the current standard koto bridges. Please refer to the 4th and 5th photos for details. If anyone is looking for these, how about taking this opportunity? I will carefully pack and ship the koto legs (2), koto bridges (15), and the dedicated paulownia wood box to prevent damage. Price negotiations are welcome. Please feel free to contact me. Thank you.
