Founded in 1945 in Nagano, Nikkoku focuses its production on buckwheat-based products, a plant also known as soba in Japan. Soba noodles, made from buckwheat flour, are already popular, but Nikkoku aims to expand the range of buckwheat-derived products with sobacha, an infusion rich in vitamins and antioxidants, buckwheat groats that can substitute for rice, and mixes for making the famous Breton galettes. In addition to developing new products and trends, the company is committed to healthy, safe, and sustainable production processes: using abandoned farmland, developing sales of products made from local resources, reducing industrial waste, etc.
