Helmet Business

As a pioneer in ABS plastic products, KAGA SANGYO continue to realize new safety solutions.

KAGA SANGYO was the first in Japan to commercialize an “ABS resin helmet” that provides both functionality and comfort.

KAGA Helmets can customize the specifications of our helmets to meet individual customer needs, including a lot of experience with firefighting helmets which often require numerous proprietary specifications.

In response to the recent increase in demand for disaster prevention needs, the company has newly developed “Osamet”, (a foldable hard hat helmet) that has the best storage capability in the industry. KAGA SANGYO is now delivering this product to the Government, elementary and junior high schools.

KAGA SANGYO’s aim is to create a safe and secure society through our helmet business.
