Seju was established in 1991 in order to develop and manufacture parts and system used exclusively in military. Up until 1998 Seju exclusively produced military parts such as Small Size Electronic Explosive Detornator (EED), Self Destruct Fuze, Shock Sensor and Reserve Battery. However, from 1998 we commenced civil demand business and now we have taken up unchallenged position in the field of sensor and system.

MEMS (Micro Electro Mechanical System) that we retain are applied to various parts and the parts which are developed by our company and systems which adopted such parts have outstanding quality and price competitiveness. Our strategy is to develop a core part of finished product by ourselves and thus to manufacture products which are cheaper than those of China and in better quality than those of Japan.
