Kouki (red wood) is a top-grade wood used for high-end furniture and crafts, as well as for shamisen (a traditional Japanese three-stringed instrument). It is characterized by its beautiful reddish-brown grain and its hard, heavy texture. Currently, the amount in circulation is decreasing, and it is widely used for repair materials, craft works, and musical instrument parts. It is a popular material that becomes more flavorful the more it is used! Please judge the size from the image. It is considerably heavier than general lumber. 1627g 489g Does not float in water.
