世界農業遺産 CHA938


CHA938 is working on "9" of the 17 goals set by the SDGs.

Handling of organic JAS mark products

In organic farming, we will circulate and use local resources and try to grow with the utmost consideration for the surrounding environment. Sustainable agricultural production helps reduce the risk of hunger.

Safe, secure and healthy tea

The average life expectancy of Japanese people is one of the longest in the world, but the problem is that the "healthy life expectancy" of being healthy is not long. CHA938's tea is centered around Fukamushicha, and because the tea leaves are fine and have a lot of powder, you can drink plenty of tea ingredients that are difficult to dissolve in hot water or water.
We thoroughly manage hygiene and supply safe and secure products.

Work rewardingly and grow the economy

The tea-grass farming method will be more appreciated, and the producers, regions, and manufacturers will work together to continue the tea-grass farming method while building a relationship of trust with the economic and environmental vectors pointing in the same direction. All CHA938 tea products come with a "Biodiversity Conservation Contribution Sticker", and a part of the purchase price is returned to the practitioner.

To an eco-friendly city that coexists with nature

The agricultural act of making delicious tea, "tea-grass farming method," contributes to the maintenance of biodiversity as a result. In particular, it has received high praise from researchers around the world at the 10th Conference of the Parties to the Convention on Biological Diversity (COP10). Various damages caused by climate change can be reduced by creating an environment that makes the best use of the ecosystem and coexisting with biodiversity.

Environmentally friendly product creation

Just put the CHA938 tea bag in my bottle and you can easily make more delicious tea than a PET bottle. Carrying my bottle leads to not producing garbage called PET bottles, and is kind to sea creatures. The tea bag is made from the biomass material "Soilon" made from plant starch. It is an environmentally friendly material that does not emit microplastic unlike general tea bags. We also use environmentally friendly shipping materials.
* Cardboard: FSC certified material
* Shipping case for cat POS: Part of the case purchase price is donated to the Nature Conservation Society of Japan

Collaborate with others to reach your goals

The use of local tea leaves contributes to improving the sustainability of the region. We will cooperate with producers, regions, and manufacturers to disseminate tea from the tea-grass farm method to the world.


Tea-grass farming method is connected by "3" pillars.

Communicating the deliciousness of tea from the tea-grass farm method to the world

Tell the world


With "8" proud things, we will deliver tea of ​​tea-grass farming method to everyone.

  1. Cooperation and understanding of people in the area around the tea grass field
    Only with this, the tea-grass farming method can be protected and continued. There is a strong awareness that it is a shared property of the region, and it is highly evaluated that it is maintained by mutual aid such as supplementing labor.
  2. Improving the motivation of tea farmers who are the managers of tea grass fields and fostering leaders
    In order to continue and inherit the "tea grass field farming method", it is necessary to train young producers who will be responsible for making tea in the future. While suffering from climate change and doing a lot of hard work in places where machines can't enter, we continue to help and compete with those around us, and continue to challenge things that are better convincing while preserving tradition.
  3. Making soil from the grass of the tea grass field
    It is thought that applying grass to the tea plantation has the effects of adjusting soil temperature, retaining soil moisture, controlling weeds, preventing the runoff of soil and fertilizer, and supplying organic matter. In Higashiyama's tea plantations, this organic matter-laden humus soil, which is rich in microorganisms, grows tasty and fragrant tea. Therefore, tea farmers have taken the time to follow this farming method. The tea leaves grown in good quality soil over the years have a special taste.
  4. Rare creatures that live in tea grass fields
    The tea-grass yard, which is maintained by human hands, is home to the endemic Kakegawa Melanoplinae and the endangered Grey-faced Buzzard. Among them, Kakegawa Melanoplinae, which can only live in places where it is necessary to "control the progress of environmental changes by regularly mowing and carrying out grass," is not a symbol of organisms that coexist with tea-grass farming. Is it?
  5. Rare flowers blooming in the tea grass field
    In the present age when the grassland environment has decreased, four species of Kawaranadeshiko, Ominaeshi, Fujibakama, and Kikyo among the seven autumn herbs have decreased to the point where they are worried about extinction in wild conditions. All of these seven autumn herbs have been found at tea plantations in Shizuoka Prefecture. Tea grass fields are needed not only for making delicious tea, but also for the coexistence of people and nature.
  6. Aracha, the raw material for CHA938 tea
    Aracha is the key to the deliciousness of sencha.The tea handled by CHA938 is a well-equipped rough tea factory that has won the Minister of Agriculture, Forestry and Fisheries Award at numerous competitions.
  7. CHA938 tea finishing technology
    It is the job of the tea master to add some effort to make delicious crude tea more delicious. The tea master, who has won the highest gold award four times in a row for two consecutive years, finishes the tea at the "Finishing Technology Competition" where the processing technology that brings out the goodness of the raw tea material is competed.
  8. "Shizuoka Tea-grass Farming Method" certified as a Globally Important Agricultural Heritage
    Globally Important Agricultural Heritage is recognized by the Food and Agriculture Organization of the United Nations (FAO) as a globally important agriculture, forestry and fisheries system for the purpose of preserving the declining traditional agriculture, forestry and fisheries industry, cultural customs and biodiversity. It is a system that has been established. "Shizuoka's tea-grass farming method" is nothing but a proof that it is recognized as a very rare case in the world where the farmer's efforts and efforts to make good tea are compatible with biodiversity.
