Head of Safety Systems Group

Business Vision

We will become a global brand that provides people around the world with safety through products that are compatible with evolving mobility technology.

Mid-term Business Strategy

We will expand our global business for inflators, micro gas generators, and squibs by globally strengthening our production systems, quality assurance systems and supply chains.

Business Profile

As Japan’s first manufacturer of industrial explosives, the safety systems business applies techniques that were gained over many years in relation to igniters, detonation and explosive combustion. In doing so, we have developed our own inflators, which are gas-generating devices for inflating airbags during car collision, micro gas generators, which are compact gas-generating devices used for retracting seat belts in the event of a collision, and squibs, which are used for igniting these devices. Currently, from our five production bases* in Japan, the Czech Republic, China, Mexico and Malaysia, we are expanding our business globally.

* Production Bases Japan: Himeji Plant
Czech Republic: Kayaku Safety Systems Europe a.s. (KSE) * The corporate name changed on June 1, 2018.

To Achieve Our Vision

The automotive industry is undergoing a period of great transformation as symbolized by CASE*, and continued growth in vehicle sales is projected and beyond, mainly in emerging countries. Automotive safety components employing explosive technologies are used in airbags, seatbelt pretensioners, hood pop-ups, and electrical circuit breakers, and the purposes of use are expected to expand along with the evolution of automobiles. Representative pyrotechnic devices such as inflators and micro gas generators are also expected to grow as the number of installation locations in vehicles increases. In the safety systems business, we will further refine the technology for these pyrotechnic devices and will also include them in new mobility technologies such as drones. Nippon Kayaku will continue to supply highly safe and reliable products as we also keep initiatives aimed achieving carbon neutrality in mind.

Product introduction

We deliver automobile safety components incorporated into air bags, seat belt pretensioners and other safety devices worldwide with reliable quality.


Inflators are devices used to instantly inflate airbags. Airbags are loaded with a gas generating agent, which applies explosive technologies to control the speed at which an airbag deploys at within 1/1000th of a second at the point of impact.

Micro Gas Generators

Micro gas generators are compact gas generating devices used for seatbelt pretensioners, which are devices to retract seat belts in the event of a collision, safely restraining passengers in place.


A squib is an ignition device embedded in inflators and micro gas generators. It receives electric signals from impact sensors to operate safety devices.
