The wood of the Zelkova tree, known as "Keyaki" in Japan, is one of the most highly regarded materials for wood products. It has historically been widely used in construction, furniture or other interior items due to its high durability and moisture resistance. During the Edo period, they were used to make bridges and boats, and even after that, houses built from high-quality Zelkova trees were considered very prestigious. The Zelkova tree grows quite luxuriantly in Japan, and the wood has a unique and eye-catching golden colour. The grain is often very beautiful and comes in many pattern variations.
