Aiming to Achieve Continuous Business Growth

What human beings always strive to achieve are “safety,” “health” and “rich environment.”

We at KOKEN have been consistently in pursuit of such unchanging values. Never satisfied with the unshakable status as a leading manufacturer in the industrial respirator market, we are striving to achieve further business expansion.

  • Our growth model

We will aim to grow and expand our business horizons by creating new markets where based on our original technology we will develop and sell “truly useful” products that “the world has never seen before” for our three business domains of “Cleanliness, Health and Safety.”

  • Cleanliness (aiming to make our technologies de facto standards in the “Cleanliness” field)

KOACH, the world’s first open clean system, is a super clean zone creator, that has totally revolutionized the world of “cleanroom.”
Without surrounding a space with walls, KOACH can form a super clean zone in an open space.

This world’s first technology that can turn an ordinary room into a super cleanroom has received the following prestigious awards.
2011 : The main award in the 2010 Best Ten New Products Awards sponsored by the Nikkan Kogyo Shimbun
2014 : The highest award (Ministry of Economy, Trade and Industry Award) at the 44th Machinery Industrial Design Awards (organized by Nikkan Kogyo Shimbun)
2015 : Japan Machinery Federation Chairman’s Award for Superior Energy Conserving Machinery at the 35th Outstanding Energy Conservation Equipment Awards (organized by the Japan Machinery Federation)
2015 : The highest award for resilience in the manufacturing sector at the first Japan Resilience Awards (organized by the Association for Resilience Japan)
2015 : The Japanese Prime Minister’s Award at the 6th Monodzukuri Nippon Grand Awards (co-sponsored by four ministries-the Ministry of Economy, Trade and Industry; the Ministry of Education, Culture, Sports, Science and Technology; the Ministry of Health, Labor and Welfare; and the Ministry of Land, Infrastructure, Transport and Tourism)

With its “super cleanliness (the highest level of cleanliness in the world)” and “actual cleanliness (capability to always maintain cleanliness during operation),” the KOACH products are certain to revolutionize the way you think about cleanliness.

  • Health (trying to develop a new business by striving to resolve various challenges confronting our customers)

This is a new business domain that we want to launch in earnest.


“KAGAMI-NAISHI” Automatic Endoscope Washer
 Nearly all hospitals that have introduced “KAGAMI-NAISHI” are fully satisfied with it, saying that they cannot work without it. Based on our sales efforts by taking advantage of such a formidable reputation, we will continue to spread the use of “KAGAMI-NIASHI” products.

“Hi-Luck” series disposable masks
Being recognized as the high performance mask to control infection, Hi-Luck series disposable masks are adopted by 70% of health-care centers and 50% of medical institutions designated for infectious diseases across the nation. To increase the sales of Hi-Luck series masks we also sell Hi-Luck Neo and Hi-Luck Neo KIDS series disposable masks to general consumers.
     Isolation of infected patients is an indispensable measure to prevent the spread of infections when, for example, outbreaks of Ebola hemorrhagic fever or new type influenza occur. Such isolation is made possible on an individual basis by having infected patients wear patients-only Hi-Luck Neo Utsusanzo series of disposable masks. As part of the mission of a mask manufacturer, we will continue to make Hi-Luck series of disposable masks known to the public and recommend stockpiling them in preparation for future pandemics.

We have developed “IMADEZE®” copper based antimicrobial agent that shows high antibacterial, antifungal and antiviral properties but is human and environment-friendly. We want to develop new business by searching for the niche market where the features of “IMADEZE®” can be fully utilized.

Although there should be many difficulties that we have to deal with in this business domain, we want to make it a major pillar of our business by continuing our challenge.

  • Safety (will promote truly useful activities that help address safety issues)

  For 10 years we have been continuing an enlightening activity to educate mask users on the importance of mask fit between the face and the mask in order to protect the wearer from respiratory diseases.

 To familiarize our excellent fit respirators including silicone facepiece, built-in fit-checker, disposable mask with FF lip cushion with the general public, we have conducted a mask fit test on over 380,000 people so far. We will continue this campaign until the whole nation has realized that “a respirator does not do any good unless it fits the wearer’s face.”

Our “Breath Response Powered-Air Purifying Respirator (PAPR)” with breath-synchronized air flow system that is developed by KOKEN for the first time in the world is called “an ideal respirator” or “an ultimate respirator” for its high level of safety and comfort.

We want to promote further spread of this product which makes it possible to ensure the safety of a wearer and reduce workloads at a higher level.

By appealing the necessity for the masks for pandemic emergencies such as bird flu, Ebola hemorrhagic fever, volcanic eruption and earthquake to organizations concerned, we encourage them to stockpile masks and to conduct a practical training session on donning and doffing of masks.

Besides strengthening further the status of the No.1 industrial mask manufacturer in Japan, we will make every effort to help promote the spread of masks for unexpected emergencies.
