For the arms and the seat, keyaki (Japanese zelkova), a broad-leaved tree that has the strength and the beautiful grain required for fine furniture, is selected among all the trees that grow and are lumbered in the area around Mt. Takao. We apply a process of bending the wood to achieve a seamless, wood-grain finish for the arms. The combination of the 13.8? steel pipe and the slender brass-plated legs creates a contrast between the keyaki wood and gold, accentuating the beauty of both.
