This is a very rare black wood for sanshin from Nakijin, Okinawa Island. It was cut in July 2024, so it probably needs to be aged a bit more. There are some cracks and slight warping, but it should be possible to make a sanshin, excluding the Nanpu-gata and Kuba Harutono-gata styles. I don't think you'll see black wood from the main island of this quality very often in the future. I am also listing other neck materials cut from the same log. How about using them for a pair of sanshin? Thank you very much.
