1.Raw material Bark of a Nasu Kouzo tree First of all you dry the Nasu Kouzo bark. 2.Next, put soda-ash and Nasu Kouzo into boiling water and simmer for 2-3 hours. 3.Immerse the Nasu Kouzo bark in running water to remove any impurities. 4.Wash the Nasu Kouzo bark again to remove any remaining impurities@and stringy pieces of bark. It is important that all of the impurities be removed from the bark. 5.Beat the Nasu Kouzo bark until it takes on a cotton-like texture. 6.Put the Nasu Kouzo bark, water and Neri into a container. Neri is glue made from grass roots. Then you mix them together. Next, scoop up the mixture using a Sukigeta and shake it backwards and forwards, side to side. This is why washi is difficult to tear. 7.The next day, you will find that the mixture has consolidated into a pile of paper. Place the paper on top of a board and use a stick to squeeze water from it. This should be carried out for a period of seven or eight hours. At this time you must be careful not to damage the paper. 8.Then carefully separate the pile of paper into individual sheets which are then stuck to a drying board using a print brush. When using the print brush be careful not to wrinkle the paper. 9.Then after you separate the good paper from the bad paper and cut it accordingly, you're finished. You need a week to make this paper. We would like to thank the artisans and the factory for showing us how washi is made. Making washi is a very difficult and serious process and requires much concentration.
