About Us

Welcome to our site

It is 29 years since our company restarted operations as Ferric Inc., a research & development company. During these years, in order to carry out our corporate motto, "Contribute to the international society by evolving the cultures into our products," we have dedicated ourselves to materialize the products that will create the most suitable circumstances for the biological objects by controlling the temperature and the moisture.

As we try to make the optimal circumstances for the human bodies as well as for preserving and transporting agricultural products by local warming, it has been always on our mind to bring out such products as are deeply rooted in the Japanese traditional culture and can provide "feeling of safety," not to mention "safety" itself, and thus to contribute to the international societies. Lately we are also putting our efforts on more design‐oriented products by orchestrating the Japanese and the western cultures together.
All of us at Ferric are working with our company philosophy in mind, “Creativity is born from both mutualism and competition; the former will bring about the feeling of security to live together and the latter will impose the seriousness.” We will keep developing the materials of originality as well as proposing the products of both functionality and good design and thus to contribute to fuse the world.
