Woods/ Finish Colors

White Oak

・ White oak is heavy and hard with a straight grain, and possesses a distinctive presence. Depending on the individual fiber structure, when the wood is taken with a straight grain a shining burl can sometimes appear within the "tiger stripes," giving the wood a richly unique look.
・ A variety of wood colors can be seen due to differences in how the tree grew. In addition, knots, which are also a sign of natural wood, are left behind in the trunk by the cores of branches. A striped wood grain is the mark of minerals from the soil that were absorbed into the trunk.
・ At Hida Sangyo, we use mainly white oak produced in North America.


・ Walnut, along with teak and mahogany, is one of the world's 3 major precious woods. Tasteful and elegant, it features soothing colors and a beautiful burl grain, and the gloss and touch also make it an outstanding luxury material. Because it contains many tannins, long use gives it a shine that deepens the texture.
・ A variety of wood colors can be seen due to differences in how the tree grew. Even in a single trunk, the difference in color between the dark brown heartwood and the white sapwood is clearly visible. Along with that, there are small living knots called, “small knots” and “bud knots,” and an undulating grain.
・ At Hida Sangyo, we use black walnut produced in North America.


・ In 1920, when Hida Sangyo's predecessor, Central Woodworking Co., Ltd. first began to make furniture, beach wood was abundant in the Hida region. It is fine-grained, dense, and sticky, and its resistance to cracking makes it suitable for bentwood use.
・ As evidence of the harsh environment in which it grows, the black stripes and wavy grain appear as light and dark shades in the wood color. The red heartwood is distinct from the white sapwood. There are also small spots across the entire surface.
・ At Hida Sangyo, we use mainly beach produced in Europe.

Japanese Cedar

・A type of cedar that grows only in Japan, it has the technical name, "cryptomeria japonica" which means, "Japan's hidden asset." In the past it was thought that cedar's softness made it unsuitable for making furniture, but at Hida Sangyo we developed a technique to increase its strength using hot compression, allowing us to commercialize it. It is characterized by its beautiful grain and warm feel.
・ When plain-sawn, the timber has many knots. Also, depending on the environment where the tree grew, small knots and bud knots may appear in a dense pattern.
・ At Hida Sangyo, we use mainly Japanese cedar produced in Gifu Prefecture.

Red Oak

・ It is called red oak in reference to the beauty of the tree's autumn foliage colors.Key features of this tree include a straight and sturdy wood grain, and compared to the white oak, a slight tint with a shade of pink which gives a warm and gentle impression.

・ At Hida Sangyo, we use mainly red oak produced in North America.
