This is a 13-string koto. It has a normal soundboard, and the soundboard has a sudatare carving. There are a few small marks where the koto bridges have fallen, but they are very minor. The strings are also hardly frayed. You can use them as they are. The sound is a beautiful, koto-like tone from the paulownia wood body. How about it for home practice for the koto club? It comes with cat's feet, bridges, a music stand, a tuner for convenient tuning, and a copy of a beginner's manual for those who are not very familiar with the instrument. There is also a yutan (protective cloth), but upon closer inspection, it has a tear. Everything is included, so you can start playing as soon as it arrives. However, please purchase your own koto picks separately, as they should be chosen to fit the individual's fingers. We support home practice for the koto club with accessories and a reasonable price.
