Structual Softwood Lumber
Yamizo spanning three prefectures: Fukushima, Tochigi, and Ibaraki. This wood features a beautiful orange color with reddish tones. Due to the good drainage in the mountains and the extremely cold winter temperatures with minimal snow accumulation, the trees grow slowly, resulting in straight grain and very fine texture. The products made from this wood are characterized by high strength.
