Corporate Profile

Message from the President

KATAYAMA SEIYAKUSYO was founded in 1922 to manufacture organic and inorganic reagents. Since then, the company has accumulated a wealth of organic synthesis technologies through its business performing contract manufacturing of chemicals for photographic printing paper, fine chemicals for pharmaceuticals, active pharmaceutical ingredients (API), and intermediates.

In this period, our company established a c-GMP-compliant pharmaceutical manufacturing control system, and underwent GMP inspection by the US FDA, the EU AIFA (EMA), and Japan's Pharmaceuticals and Medical Devices Agency (PMDA). As a pharmaceutical contract manufacturer able to comply with the requirements of these three agencies, we have earned the acclaim and trust of numerous pharmaceutical firms.

Furthermore, to meet customers' stricter standards, we are aiming to improve QCD (quality, cost, and delivery), by expanding our facilities, strengthening our capabilities for process development, and improving our technical services. Also, we joined the Sakai Chemical Industrial Group in February 2012, and acquired a firmer management foundation.

Going forward, too, we will contribute to society through contract manufacturing of APIs and intermediates, undertake challenges responding to changes of the times as values become highly diversified, and push forward into the next 100 years.

We thank all our stakeholders for their continued support and patronage.


To achieve healthy lives and a prosperous society, we will:

  • Contribute to the creation of medicines through organic synthesis technologies
  • Provide new values through technological innovation in organic and inorganic chemistry
