d:matcha Kyotoโs
Organic Tea Farming
We grow our tea hand in hand with the natural ecosystem of Yubune, Wazuka. No pesticides, no herbicides, and full transparency from field to cup.
Our Tea Philosophy
Organic
All of our teas have been cultivated organically since we founded d:matcha. In 2025, after years of transitioning our soil, we officially received Organic JAS certification, Japanโs national organic standard. No pesticides, no herbicides, no synthetic fertilizers.
Single origin
Every d:matcha tea is made with 100% Kyoto-grown leaves and processed in our own factories in Wazuka, Kyoto, the heart of Uji tea production. From field management and harvest to processing and packing, every step is handled by our small team.
Single cultivar
Our matcha and sencha lineup is designed so you can taste each cultivar on its own and understand the nuances of Kyoto terroir. Umami, aroma and texture vary beautifully from one to the next.
Better tea. Better for you. Better for the land.
For your cup
It makes the most delicious tea.
This is the reason we farm organically. Healthy, living soil and a balanced field let the character of our land, climate and cultivars come through in every harvest, rather than being flattened and homogenized. Organic tea has a depth and nuance you wonโt find in conventionally grown teas.
For you
Nothing in your cup that shouldnโt be there.
With matcha you drink the whole leaf, so what goes on the field ends up in your cup. We use no chemical pesticides, herbicides or synthetic fertilizers, and run independent lab checks every year to make sure our tea meets our standards.
For the land
What happens on the farm doesnโt stay on the farm.
Tea is one of the most heavily fertilized crops in Japan, because high nitrogen drives umami. When that nitrogen comes from large doses of synthetic fertilizer, much of it is never taken up by the plant.
Heavy synthetic fertilizing
Excess nitrogen acidifies the soil and damages feeder roots.
Unused nitrogen washes out as nitrate into the streams, damaging the surrounding environment.
Acidified groundwater dissolves aluminum and other metals from the ground and carries them into the river system.
Our way
We analyze our soils and use diverse natural materials, split into about four applications a year so plants absorb what theyโre given.
Without pesticides, spiders, dragonflies, mantises, ladybugs and frogs return and keep pests in balance.
Healthy soil holds its nutrients, the stream below stays clear, and the leaf you drink carries nothing it shouldnโt.
Organic tea farming is more work. Here is what it looks like.
Living with nature
We never use pesticides or herbicides. Instead, we work with the natural biodiversity of Yubune. Spiders, dragonflies, mantises, ladybugs, frogs and other native predators keep leafhoppers and caterpillars in balance.
Our fields are alive with nature.
Hand-weeding
Weeds compete with tea plants for nutrients, harbor disease and can block sunlight. So we remove them by hand, carefully and frequently. Ferns and other plants that grow between the bushes can only be pulled by hand.
This coexistence with nature lets the character of our land, climate and cultivars shine through each harvest.
Fertilizing the soil
Delicious organic tea depends on soil health. We analyze our soils, then choose natural materials for what each field needs. We use 100% natural fertilizers derived from plant and animal products, which nourish both the plant and the local ecology. This slow-release approach lets the tea develop a deep, complex character over time.
Organic does not mean compromise.
Analytical comparisons show that d:matchaโs organic teas often match or even surpass conventionally grown Uji-region teas in key components such as amino acids and catechins.
This comes from consistent soil management, precise fertilization and the natural strength of organic cultivation. We chose organic not only for safety and sustainability, but for taste and quality.

Third-party audits and independent lab analyses, published in full. Results for 2025 and 2026.
Organic JAS
Japanโs official organic program, run by the Ministry of Agriculture, Forestry and Fisheries (MAFF). It prohibits synthetic fertilizers, chemical pesticides and GMOs, and requires annual third-party audits.
Every tea with the Organic JAS seal is grown 100% organically in our own fields in Yubune, Kyoto.
