はじめに Introduction

The softness and transparency of Japanese paper seems to represent the land where raw materials were harvested under crisp air and beautiful water. The warmth and the strength of Japanese paper comes from the effort and love of raw material farmers living in that land for generations. Through the ties of local people and nature, Kashiki Paper Co.,Ltd. has been able to produce Japanese paper.

良い紙は良い原料から Fine paper is made from fine material

What makes our company unique is the high value we put into our materials. “Use only finest materials” was the philosophy we inherited from generations ago and when the market started to depend heavily on overseas materials, our company’s philosophy changed to “Use only finest Japanese materials”. This belief is what we value at Kashiki Paper Co., Ltd. even now.

Our paper is produced from raw materials purely made in Japan. We utilize Tosa kozo and mitsumata (90% of our paper production), and Nasu kozo and gampi grown in Okayama prefecture (around 10%). We highly value using these materials in order to produce high quality paper.

清流仁淀川の恵み Blessings from the Clear Stream Niyodogawa

The clear stream Niyodo river is located in Ino, the town of Tosa washi. When producing paper, we use underground water. It is crucial to have rich and clear water in all steps of process paper; boiling, water bleaching, removing impurities, and making paper. Abundant water resources and our natural environment support paper making.

守り継いだ製法 Preserving the traditional way

We have been using the same paper making process for generations. The same method is used to process raw materials, both for machine-made and hand-made paper.

鹿敷和紙製造工程Kashiki Washi Manufacturing Process

1. Boil
Boil materials in the stainless-steel pot with alkaline solution, such as calcium hydroxide, sodium carbonate, and caustic soda.
2. Water bleaching
Soaking the material with water which is retrieve of beneath the earth from Niyodo River. (When using caustic soda for boiling, wash the material and bleach them with sodium hypochlorite. Carefully water bleach the material again.)
3. Removing impurities
Carefully remove all impurities.
4. Dehydration
Dehydrate the materials to remove moisture.
5. Beating
Moderately re-moisturize the materials and beating them evenly.
6. Defibration (isolating and preparing fibers)
Use the “Naginata” beater to separate the Kozo fibers. Use the Hollander beater to separate Mitsumata and Gampi fibers. Place them over a mesh screen.
7. Paper making
Place the materials into the beater in the production line, then add "Nori" (a mucilaginous agent) to disperse fibers. The fibers are transferred onto a bronze wire rack. Now formed by the rack into a large sheet, it is moved again onto a wet blanket. The fibrous sheet is run between two rollers, one wet and one dry. The pressure from the two rollers extracts the moisture from the fibrous sheet. Then, it is transferred onto the dry blanket and pushed forward into a stainless steel dryer to be dried completely.

技を継ぎ心をつなぐ Passing down the skills and the hearts

Paper is passed on, starting from local raw material farmers, to processors, to paper producers, to dealers and then to users. Kashiki Paper Co., Ltd. have not only passed down the traditional paper making skills but has also been a pioneer in inventing new skills over time. We have invented new types of paper to match various usages. Although we started using the machine from 1974, we wanted the paper making process to be as similar to the hand-made paper process as possible. Therefore the same materials have been used for production. Moreover, in order to produce the same texture as hand-made paper, we studied the machine and decided to slow down the rolling process. As a result, our machine-made paper is as good as high quality hand-made paper.

1000年の時を継ぐ Passing down for more than 1000 years

In fact, there is no clear definition what kind of “paper” washi is. There is a saying in Japan, “Washi lasts 1000 years and yo-shi lasts 100 years.” From this saying, we believe “genuine washi” had excellent storage stability. We value preservability and with the aim to produce “genuine washi,“ we use raw materials grown in Japan and apply the same production method from the old times to process raw materials. We have avoided using iron for parts like the dryer, pot and arms of the machine and so on. We introduced stainless-steel and brass to maintain the paper longevity, and to stay “genuine”.

In 1982, HAMADA Shigenobu, the second Representative Director of Kashiki Paper Co., Ltd, visited restoration sites in France. As soon as he returned to Kochi, he developed the ultra-thin kozo paper to be used for restoration. The paper soon received acknowledgment and since then it has continued to be used to restore ancient documents or national treasures in Japan, as well as art galleries and museums around the world. We intend to make conscientious efforts to make genuine washi to keep the techniques of generations.

和紙は呼吸する Japanese Paper that breathes

Washi has high surface tension and is flexible. It also creates layers of air which shuts out sound and humidity. That is why it is widely used for fusuma and shoji (papered sliding doors), ceilings, and wall paper. During good weather the air seeps outside through the paper and during bad weather the humidity stays inside. This paper complements the people’s five senses and their lifestyle.

— Hiroaki AGETA from AGETA kunpudou

良い紙を漉けば用途は後から開けてくる When fine paper is made, it will be utilized unlimitedly

Our predecessor believed that “when fine paper is made, it will be utilized unlimitedly” and that has been Kashiki Paper Co.,Ltd.'s core value. In order for the users to use our paper for various situations, we provide thin to thick papers (3g/m2~100g/m2) with consistent quality.
