KOSYUEN's effort for quality and safety
100% organic tea leaves harvested in JAS certified tea plantations.
It took us more than 3 years to have fertile soil without using any pesticides and fertilizers; enabling us to cultivate an environment that makes full use of the power of the nature. Try the natural taste produced with the utmost effort of our tea farmers.
Other than our organic products, we ensure our customers quality and safe products through strict inspections. Through our elaborate examination facilities and our professional staff, we can complete a severe inspection. We inspect our products to check residuals of agricultural chemicals and foreign objects through a metal detector. Furthermore, we carry out bacteriological inspections based on the Food Sanitation Act.
