CRUDE TEA
Potential output of approx.

With integrated production that cuts out the middlemen, our unique system allows us to offer high-quality tea at reasonable prices.
FINISHING
Approx.
5,000kg / day
We sort the tea leaves selected at our strictly hygiene-controlled factories and carefully inspect them for firing, aroma and appearance, etc., on our integrated production line.

SATOEN
Food and Drug Laboratories

A thorough system for ensuring quality from product development
and production to manufacturing and sale
We utilize state-of-the-art-equipment for agricultural chemicals inspections and radiation testing, etc., to check that we meet our own strict standards.
Agricultural chemical management
and radiation testing
For agricultural chemical management, we conduct simultaneous analysis screenings for 200–300 types of residual pesticides. And in addition to testing for radiation, we can also conduct separate analysis for individual pesticide components at the customer’s request. Satoen remains the only company capable of such thorough in-house analysis.
Each lot is analyzed for radiation and residual pesticides
