About us  

"From the Ocean to Outer Space"

   NiGK Corporation was fully financed and established by NOF CORPORATION in December 1980. Inheriting the know-how accumulated by TEIKOKU PYROTECHNICS MANUFACTURE CO., LTD., which had lasted from 1938 to 1970, and that of NOF CORPORATION, Kawagoe Plant which succeeded it, we have promoted research and development in various fields in parallel with manufacturing of pyrotechnics and temperature indicating materials and other products. 

  With on ever-expanding scope of our business, our products have been patronized in different fields widely ranging from the deep seabed to outer space, as indicated by our catch phrase, ""From the Ocean to Outer Space,"" contributing to safety and reliability of various systems.
