Greetings

We are aiming to become a global KEIWA that contributes to a cheerful world and to future societies.

Since its founding in 1948, Keiwa has never been satisfied with its current status and has always taken the initiative to act first.

We have actively innovated marketing methods, technologies, and various systems in order to proactively, quickly, and accurately respond to the ever-changing needs of customers. This approach is called "dynamic domain", which is our management policy.

Initially, we were founded as a supplier of waterproof paper to the textile industry to support Japan’s postwar reconstruction and then gradually grew as the leading processed paper manufacturer in West Japan. We grew rapidly and achieved a major leap by supplying various function products, such as moisture-proof packaging materials, processing materials, protective sheets for natural gas and oil pipes, to the chemical industry and the steel industry undergoing international expansion. At this point, possessing three distinctive technical systems of sheeting, laminating, and coating, our company had solidified our status as one of the few global manufacturers of function products.

Since then, the company has survived recessions caused by two oil crises and the collapse of the economic bubble. However, due to the spread of the Internet and the advancement of the information society, the field of display devices used for various digital equipment has recently become one of the few "expanding industries" in the period of low growth.

Responding to the needs of the optical industry, we have come up with an innovative solution of the diffusion film-"Opalus". We have obtained unparalleled performance in this niche segment.
Entering this year, we started with customer-oriented marketing and further refined our core technologies of sheeting, laminating, and coating with the addition of Ultra-Precision (high accuracy) technology, with the aim of becoming a manufacturer of functional films and solutions.

Furthermore, along with business expansion, we continue to accumulate and develop technologies to maintain and improve the world environment.

As a global-minded company, we work with our subsidiaries in Japan, Taiwan, China, South Korea, and the United States to promote collaboration with companies around the world.

Based on our business philosophy of "Creating Harmony between Nature and Industry", Keiwa Group will make further contributions to the future of our earth and society.

Management Principles

Creation of the Harmony
between Nature and Industry.

Human beings benefit considerably from Nature and the products they make.
However, if these products are not in harmony with Nature, their benefits cannot last long.
To achieve this harmony, it is necessary to acquire precise wisdom and technologies based on a long-term perspective and flexible thoughts.
We constantly enhance our creativity and assertiveness as an organization to provide this kind of wisdom and technology.

Management Vision

Aiming to be a CSV group that creates shared values
between nature and society through providing high quality"
