About organic farming

"Tea production that respects people and the natural environment"

The term Organic in its purest essence equates essentially  to Organic Farming.

It is a production method good for both the soil and global environment alike, making most of and fully utilizng the power of the natural world: the elements which nature has so perfectly provided for... rather than relying on chemical fertilizers or synthetic pesticides.

Organic farming is also a way of living with nature and by her natural rhythms. Not going against this flow, but working in harmony with it.

Making tea that works in tandem with, not against nature ... Making tea that is beneficial to people and the earth.

All life on earth is connected by a food chain.

For humans to continue to be robust and thrive into the future, we should not go against the current of nature; we should thank the soil and aim for a sustainable future in which microorganisms, plants, and all living things on the earth coexist together.

OSADA TEA aims to make tea that lives up to this standard, and incorporate the above philosophy into a real business model, to the joy and satisfaction of our customers.



Reliable and safe manufacture of tea ... we will deliver "organic sencha" refined by the abundance of nature and finished by human hands.

Due to problems related to low transparency of"food information", the "normal" method of circulation of such information has been under scrutiny for several years.

In response to this, the new JAS law revised in 2000 was also strengthened in 2002 with extremely strict penalties for food business operators.

"Organic agricultural products and organic processed foods" are labeled as "organic" except for those rated by producers and manufacturers certified by the organic JAS registration and certification body and bearing the organic JAS mark. Has been banned and continues to the present day, and strict organic JAS certification standards that do not allow the use of chemical fertilizers and pesticides are applied. In addition, regarding "specially cultivated agricultural products", the notation "pesticide-free cultivation" is often perceived by general consumers as having no residual pesticides, and from "organic JAS certification" which complies with strict international standards. In 2003, there were complaints that more than 60% of consumers misunderstood that it was excellent, and that the standard for "pesticide-reduced cultivation" was difficult to understand. "Relevant labeling guidelines" have been revised and unified into the notation "specially cultivated agricultural products", and notation if the usage rate of chemical pesticides in conventional cultivation is 50% or less, and the nitrogen component of chemical fertilizer is 50% or less in conventional cultivation. Is allowed, and the usage status is to be indicated on the back side.

Therefore, from April 2004, the labeling of "pesticide-free" has been legally prohibited from food labeling and continues to the present day.



What are "organic sencha" and "organic cultivated tea" certified by Organic JAS?


The "organic cultivation of tea" is a recycling type of environment including conservation that works with the rhythm of nature, and one that has been born out of deep reflection after seeing directly the environmental impact of  conventional methods of tea cultivation.  The conventional method has increased the environmental load of the soil and tea field's surrounding habitat due to excessive application of chemical fertilizer used to emphasize the umami flavor of tea.

At Osada Tea we wish to aim for agricultural methods that alongside nature.

We enjoy abundant nature in this area and have a good initiative for a business that pushes toward mass production of tea based on organic cultivation while avoiding pesticides. We are in the business of growing strong, robust organic tea fields, and supporting the farmers who have developed this skill over many years. A large key in all of this is the soil's treatment with pure materials and compost.




About Organic Certified / Tea Producers


First and foremost, we do not use any chemical fertilizers or pesticides in our tea plantations for more than 3 years beofre submitting a field for inspection to become certified organic.

It is also necessary to have our tea fields be wisely positioned so that pesticides sprayed from other tea gardens do not drift over and stick to our tea fields. The main agricultural trend in Japan is to apply pesticides to tea fields, so keeping a distance is vital.


On top of that, it is necessary to obtain certification from an organic JAS certifying body and manage and record all processes of the production process. In the case of tea production, it is vital to steam as soon as possible after picking fresh raw leaves to halt oxidation of the leaves, or "fermentation". After this intial steaming of tea leaves, an important processes in and of itself with many variables that determine the teas composition, tea is processed into a semi-final product called "aracha".  The processes of plucking leaves to producing aracha occurs as quickly as possible on the same day.

About Organic Certified / Tea Manufacturers


Tea wholesalers act as manufacturers of tea as an agricultural product.

The tea maker purchases semi-processed aracha from the producer, refinishes and processes it, stores it, subdivides it, tank-blends it, ranks it, attaches the JAS mark, packs, then ships it to the place of consumption. Throughout this processes, quality control must be performed so that organic tea is not mixed with tea grown by conventional means, and a tea professional must confirm whether the tea meets JAS standards while recording the process.

The reliability of tea with the organic JAS mark is slowly increasing among Japanese consumers, and it is expected that it will continue to increase in the future.

From a global perspective, organic food potential in the EU and North America is growing into large markets, and "Japanese tea" is becoming more and more popular overseas as a healthy and wonderful product (and piece of Japanese culture), even moreso than in Japan- especially organic teas.

The situation is such that "Certified Japanese Tea" is a difficult situation in Japan.

Following "Slow Life" and "Eco", "LOHAS" started from an American marketing magazine ... "Sustainable lifestyle oriented toward health and the environment" is also becoming more accepted in Japan.

Even here, "sustainable agriculture that aims for increased health and environmental awareness", that is, "organic tea", will be recognized as a tea that brings an extra layer of prosperity to all level of human health and social interaction.
