Shima-kuwa (Island Mulberry) refers to mulberry trees that grew on islands like Mikurajima and Miyakejima, and were used in Edo sashimono (traditional Japanese joinery). Because the wood grew in an environment exposed to sea winds, its quality differs significantly from mainland mulberry, to the point where it feels like a different type of wood, and it is also quite hard. However, the amount that circulated was very small, making it a highly valuable wood. The item for sale is the root portion of Shima-kuwa, likely the remnants of veneer used for the mirror panels of Japanese furniture. It is in a raw, unfinished state. If anyone is interested, please consider it.
