Thank you company

Thank you to our customers.

Thank you to the supplier.

Thank you to your friends.

Hidaka Washi has been working on Japanese paper manufacturing, taking advantage of traditional raw material processing from handmade Tosa Noritomo paper to the needs of the times.

We challenged, solved the strict demands of customers that change, and worked on improving our technical grades and developing new technologies, and raised them as a small but unique paper manufacturer.

Not paper, but Japanese paper. Our company name has a commitment to the paper. We aim to be a company that can continue to challenge new technologies and new materials and promise our customers.

Old, good, new paper

At first glance, the Hidaka Washi Tosa Norito paper paper is a handmade and handmade while making a machine. We will give you such a nice evaluation. Both machine making and handmade are the same in principle.

It is possible to make it possible because of the raw material processing technology of handmade lords. The craftsmen say that good paper is determined by the processing of this raw material. In the Hidaka Washi, the preparation up to the stage of making paper is almost the same as the hand -made Japanese paper era. We do not spare time with the heart of mulberry, the heart of the water, and the heart of the hands, and repeatedly washed with water washing and carefully removed.

We will continue to make old, good, new paper, from the scribble paper to the unprecedented new taste paper paper.

Take it sincerely and realize it

Washi, which is said to be the thinnest in the world, is actually a product that was triggered by the user's request, "I want you to make this." Customers will give you various opinions about the Japanese paper you always use.

In response to the request, the Hidaka Washi craftsmen repeated trial and error by changing the color of the eyes if they respond to the request, whether the creator has been ignited. It was the world's thinnest Japanese paper as a result of repeated trial and error, taking the user's voice seriously. We will continue to respond to requests as much as possible and continue to respond. And I want to continue to be realized.

Make the thinnest paper in the world

Tosa Noritomo Book is a mulberry paper that boasts thin enough to be described as "Kagerou no wing" and features a thin and sticky paper quality. Currently, we are delivering 2.0 grams per flat rice. It is a ultra -thin paper, which is said to be the best in the world of only 0.02 mm.

It is only our company's paper technology that can make such a thin paper mechanical. If you do not have any balance, such as raw material processing and machine adjustment technology, you will not be able to torn and strain quickly. Delicatingly made of our scribble paper is used not only in the United States, Europe, and the Middle East as a paper that supports damaged paintings, books, and Buddha statues.

Unused chlorine bleach

Hidaka Washi is not only thin, but also focuses on the whiteness of a divine paper. It is our original bleaching technology that was born from the needs of the customer "white paper close to unprinted". In general, paper is bleached chlorine, which remains on paper as a residual chlorine, causing yellowing, discoloration and paint change and deterioration. Then it is not suitable for restoring old documents and art. Since our paper is unused, the amount of residual chlorine is almost zero. Furthermore, by repeating polite washing, the weak alkalinity of pH7, which is close to neutral and non -exposure, has been realized. Fluorescent dye is not used. As a Japanese paper that is ideal for long -term storage and restoration and reinforcement of records, the Shikoku Economy, Trade and Industry Bureau has "developed and developed an original Japanese paper with a new raw material processing method on the traditional Tosawa paper". I also received it. We will continue to deepen our skills as a paper that supports the repair field.
