Certificates & Quality
Road safety is our responsibility.
Our company obtained its ISO 9002 certification in 1996, followed in 2001 by JIS certification. These certifications demonstrate our commitment to outstanding quality and win the trust and honor from our customers over three decades.
All people in YHC are fully committed to our mission of maintaining sustainable operations and fulfilling our obligations toward society, and we keep on improving our existing products and developing new ones. In our commitment to safer roads, we have hired outstanding people who helped us create, refine, and manufacture products such as reflective road markings, energy-saving reflective markers, or anti-glare systems. These products have been well received by the industry and are widely used.
