<background>
Bamboo, which grows in 3 to 4 years, is a very effective material in terms of SDGs and sustainability. It is also very strong, and is increasingly being used in a variety of products.

As you all know, bamboo has nodes. Bamboo is strong and difficult to process, but the strength of the nodes is different from the other parts, making it even more difficult to process.

Because the strength of the fibers changes only at the knots, even if the wood is cut in the same way as the other parts, it will end up with frayed edges or dents at the knots.

Because of this, the finished bamboo plates had dents and scratches at the nodes, making them incomplete products. If the nodes could not be used, they would have to be discarded, which would increase the price of raw materials and waste a very sustainable material.

<Patent Overview>
Nakayoshi Shoji designs and manufactures its own tools and blades used to process bamboo plates, and has developed a unique polishing process after cutting, developing the technology to utilize bamboo nodes for plates.

The technology to utilize bamboo nodes, which had not previously been used in plates and other products, has been recognized and patented.
