We are a manufacturer of equipment and devices founded in 1935. We mainly manufacture deodorization equipment, exhaust gas treatment equipment, and production equipment. We are expanding our business by quickly responding to customer needs with our integrated handling system covering from design and manufacturing to installation and maintenance. We have an extensive track record of deliveries to major companies in the electric equipment and construction industries. We also manufacture nonferrous metal products, with a focus on material for radiation shielding. Our radiation shielding mat is utilized as a product to shield radiation at the site of the Fukushima nuclear power plant accident. It is also utilized for regional disaster prevention activities. We have an overseas production base in Shanghai, China, and we are accelerating our expansion to Southeast Asia.

[Company strength]
We have been manufacturing various kinds of environmental equipment and labor-saving automatic equipment and contributing to our client companies since our foundation. We now have several factories in the Kanto region. We have arranged an integrated system covering from design and manufacturing to installation and maintenance in order to quickly respond to customer needs. We have confidence in our strengths in developing manufacturing technology, and we have acquired multiple patents. We also manufacture many products that contribute to the public interest. We manufacture a radiation shielding mat as a product to protect human life and safety. Our radiation shielding mat is utilized for regional disaster protection activities. It is also used as a product to shield radiation at the site of the Fukushima nuclear power plant accident.

[Strength of products/technologies]
We focus on developing various products. NT Hyper activated carbon for deodorization is an example of our newly developed products. It is characteristic of this product that three kinds of deodorization processing, for acid, neutral, and alkaline substances, can be carried out at the same time. It is necessary to use three kinds of activated carbon separately according to the nature of the absorbed components in ordinary deodorizing in the sewage disposal process and so on. We succeeded in simultaneous processing of three kinds of components by loading a halogen compound and metal catalyst with activated carbon. The service life of our product is extended compared with conventional products because of its catalytic action. The service life can be extended to about four to five years from the normal lifetime of two years, although this depends on the use environment.

[Representative's message]
We have been expanding our business since our foundation in 1935 under the corporate philosophy of serving society through our daily work. We recognize our heavy responsibility in our products, which become public assets in many cases. We are always conscious of maintaining a sincere spirit of Monozukuri craftsmanship. We want to seriously deliberate on our products, installation work, and services to promote creation and evolution, and to pursue real value for our customers. Our goal is to be genuinely accepted by our customers.
