The “Kumiko” woodwork technique was developed in Japan in the Asuka Era (600-700 AD). Tanihata uses this technique to manufacture Ramma for room dividers and sliding doors. Wood chips are thinly and precisely shaved then carefully assembled chip by chip to construct Kumiko Ramma. Wood goes through a process of selection, grinding, splitting and assembling. Tradition is preserved through the craftsmen’s experience, skill and passion.
