Environmental Management System

ISO 14001 implementation

Our old Design & Manufacturing Center (D&M Center, now the Keihanna HQ) was certified under ISO 14001, an international standard for environmental management system, in March 2004. This expanded to include Tokyo office resulting in our being ISO 14001:2004 certified in March 2006.

ISO 14001 (2004) Certification:
March 2004: D&M Center
March 2006: Entire company
Registration number: JQA-EM3813

Environmental Activity

As part of our in-house environmental conservation initiatives, we have been working to reduce CO2 (electricity consumption), resource consumption (paper), and waste.

* Since 2008 recycling rates have been used.

Environmental Education

To raise awareness of environmental issues among employees (including part-time and temporary staff) and promote initiatives to address them, we offer environmental education in new employee training, technical training, internal auditor training, and other general training opportunities.

Environment Friendly Manufacturing

Compliance with to RoHS Directive

We strive to eliminate the use of chemical substances defined by the RoHS directive as well as the other hazardous chemical substances we specifically control. This initiative is pursued by all divisions involved in products such as sales and marketing, product planning, design and development, parts procurement and manufacturing, and quality assurance.
As for European RoHS Directive (EU)2015/863 (including the other hazardous chemical substances we specifically control), often called new RoHS2, our work for compliance was complete in July 2018, and as of July 2019 all our products except for certain OEM products, are compliant.

RoHS Directive
The RoHS Directive, which came into force in the EU on July 1, 2006, restricts the use of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) in electrical and electronic equipment. This directive was redefined as RoHS2 on January 3, 2013, and with four additional substances, namely phthalate compounds of DEHP, DBP, BBP and DIBP on July 22, 2019 new RoHS2 has now been effective.
