Teikoku Seiyaku is a leader in developing, formulating and adapting products for large-scale manufacturing, and distributing them in over 40 countries. We go beyond GMP guidelines to offer the highest quality, most innovative and efficient manufacturing capabilities in the industry.

Teikoku's one-million-square-foot hydrogel patch production facility in Japan — the largest of its kind in the world — is fully equipped with new robotics and has been qualified by the FDA, European regulatory authorities and Japan. The facility sets the gold standard in the industry for quality and safety, and can produce up to four billion patches annually —more than five million each day. Yet, even with such large-scale production capabilities, our operations are nimble enough to quickly and effectively respond and adapt to our customers’ often-changing needs.

Over 200 products are currently manufactured in several manufacturing facilities throughout Japan.
