Acquisition of ISO 14001 Certification
SII first acquired ISO 14001 certification at the Takatsuka Unit (Matsudo, Chiba Prefecture) in November 1996. Currently, every site in Japan, including offices, has acquired certification, and integrated certification was acquired in January 2015. The head office of Seiko Holdings Corporation (now Seiko Group Corporation) also was included in the scope of certification in November 2021. Overseas, each major local subsidiary has acquired certification.
