Origin of Company Name
With the arrival of the science of chemistry at the end of Japan's Edo period, the word 'chemie' (meaning 'chemistry' in Dutch) was given the Japanese pronunciation 'sha-mi.' 'Sha-mi' was then altered to 'sei-mi,' which sounded more appropriate in Japanese for a manufacturer of flavor, and Seimi Chemicals was born, retaining the name to this day.
