Company Philosophy

We will sincerely work to solve problems in the preservation of paper materials such as books and historical materials through various materials preservation technologies such as deacidification treatment. The goal is always to preserve the paper materials stored in libraries, archives, or specialized institutions in a state where they can be used 100 years later.

The result of the deacidification process is to pass on the actual paper materials to the next generation as assets, so the effort to leave as many books and documents as possible to the next generation is to convey unbiased information to the future. It is nothing but work to do. We sincerely hope that by preserving as many physical materials as possible, information that will enrich and energize people's lives will be passed on to future generations.
