A black koto with a Mt. Fuji design, accompanied by sheet music and a certificate. It has been stored for a long time, but both the koto itself and the lockable case are in very beautiful condition. I pressed the buttons to test it, and it produces sound, but I am not an expert, so I cannot confirm whether the scales and other functions are working correctly. Please understand this before purchasing. In addition to the songbooks, instruction manual, and warranty that were stored with it, I will also include the items in the first photo, such as spare strings and picks. Please note that the paper items have some stains.
