This is a Chinen Daiku sanshin used by a certain sanshin teacher. It uses Yaeyama Kuroki (black wood) and is built solidly. There are no bends or warps. The owner was playing it regularly until last year. If needed, I can restring it and let you try it out, and then provide comments. Because it's an old Chinen Daiku, the dimensions are slightly larger than those currently available. It might be a matter of personal preference, but it's quite a bargain for those who like old sanshin. Also, the wood alone is valuable, so you could even reshape and modify it to your liking. Artificial skin. It will be delivered after proper maintenance. The doumaki (body wrap) will be replaced with a new one. If you have any requests, such as changing to honbari (real skin), please comment. For those who purchase it, I will share the name of the teacher who used it.
