Certified with ISO 9001 and ISO 14001

Ahead in our industry, in 1995, all our factories(Hokkaido, Niigata and Okayama) were certified with ISO 9002 for the quality management. The switchover from ISO 9002 to ISO 9001(2000 version) was completed by all factories in March, 2003. In sequence, certificate of ISO 14001 regarding the environment management were approved to these three factories in January, 2000.
Under spirits of such international standards, we are serving societies through improvement of product qualities as well as protection of environment systems.
