Organic matcha and pesticide-free matcha: what the tests really reveal

Article published on May 29, 2026.

Are you looking for pesticide-free matcha that’s been carefully grown and is fully traceable? The natural instinct is often to go for organic, and that makes sense. But when it comes to matcha, the label doesn’t always tell the whole story.

What the organic label really guarantees

Organic farming is based on a specific set of guidelines: a ban on synthetic pesticides, traceability, regular inspections, and compliance audits. It serves as a useful benchmark, and in many cases, it already instills a real sense of trust.

However, an organic label does not tell the whole story about the final product. It primarily certifies that production methods comply with specific standards, not that the finished product is completely free of residues. Furthermore, standards, inspection procedures, and administrative requirements may vary from country to country (Ben-Othmen, 2025).

For these reasons, independent testing remains important, especially for a product like matcha, which is consumed in its whole-leaf powder form.

The special case of matcha

Matcha isn't like other teas. You don't just steep the leaves—you consume the entire leaf, ground into a fine powder. To understand what matcha is, we recommend reading this article.

In other words, if even a trace of residue is present, it ends up directly in the cup. That is why the issue of purity is particularly important for this type of product.

The production process also matters: shade-grown cultivation, leaf selection, fine grinding, and Japanese craftsmanship. Matcha is a precision product, which explains why traceability and analysis play a significant role in purchasing decisions.

Organic Food in Japan

Japan has its own organic certification system, known as the JAS (Japan Agricultural Standard), which is overseen by the Ministry of Agriculture.

In practice, this system can be difficult for small-scale producers to access, as it involves high audit costs, complex and ongoing documentation, and burdensome administrative procedures; furthermore, unlike in the EU or the United States, there are no financial support measures in place (Sawanobori & Babicz, 2006).

“The economic and administrative burden on producers has grown all the heavier, even though it was virtually impossible to offset these new expenses.” — Sawanobori & Babicz, 2006

As a result, some producers farm without synthetic inputs but do not seek certification because they are unwilling or unable to handle the administrative burden.

This is an important point to understand: in Japan, the absence of an organic logo does not automatically mean that good agricultural practices are not being followed.

Agriculture that remains largely marginal

Unlike in Europe, organic farming remains relatively niche in Japan. To understand the sector, here are some figures from the Japanese Ministry of Agriculture (2025):

Certified organic farmland accounts for only 0.8 to 1% of Japan's agricultural land.
Specifically regarding tea: approximately 4,486 tons of JAS-certified tea out of 68,000 tons produced, or just 6.6%. In other words, 93.4% of Japanese tea, including matcha, is not certified organic, even when it is grown using practices that meet or exceed organic standards.
In 2023, an estimated 3,900 farms are JAS-certified, while roughly twice that number practice input-free farming without holding the certification.
Organic market growth in Japan has been virtually flat in recent years, with a projected increase of 0.2% between 2023 and 2028 (Global Organic Trade Guide, 2024).

Why Analytics Matter

At Milia Matcha, our matcha undergoes rigorous testing by an independent laboratory with every harvest. We have entrusted our analyses to Eurofins Dr. Specht, a world-renowned laboratory that has specialized in the analysis of tea, herbs, and spices for over 50 years. With a multi-residue method covering nearly 700 active substances and their metabolites, it is one of the most comprehensive and rigorous laboratories in the world for this type of product.

The goal is simple: to verify what the product actually contains, harvest after harvest, rather than relying solely on a certification or a claim on the packaging.

This approach is all the more relevant given that there have already been recalls of matcha and organic tea due to pesticide-related non-compliance, and that some organically farmed plots may be adjacent to conventionally grown crops treated with pesticides, posing a risk of contamination from spray drift. In this context, analytical transparency becomes a key factor in building trust.

What we actually do

Here are the three key points of our approach:

We work with a specific producer in Japan. As a result, we are familiar with their methods and each of their plots. This direct relationship is our first line of assurance.
With every harvest, our matcha is tested by Eurofins Dr. Specht, an independent laboratory specializing in tea analysis. No pesticide residues were detected, including glyphosate.
We make our analyses available to everyone. You can view them right here.

How to Choose a High-Quality Matcha

Before you buy, ask the right questions. You can’t judge good matcha by its packaging alone.

Check whether the brand can clearly tell you:

Where does matcha come from?
who produces it,
if the analyses are independent,
if the results are recent,
if the documents are available.

A label can help narrow down your choices. But when it comes to a product as delicate as matcha, it’s concrete evidence that makes the difference.

Heavy metals

Beyond pesticides, the issue of heavy metals is just as critical. Naturally present in the environment, they are inevitably found in trace amounts in most teas. What really matters is not so much their presence as their precise concentration, rigorously quantified through laboratory analysis. For more details on the results obtained for our matcha, we invite you to read our dedicated article on the subject.

Conclusion

The "organic" label remains a useful guide. But when it comes to Japanese matcha, it alone is not enough to judge the product's true quality.

Given the differences in certification standards, administrative constraints in Japan, and the limitations of a label that primarily describes a process, it makes more sense to also consider independent analyses and actual traceability.

It is this combination that makes it possible to choose a matcha that is clearer, more transparent, and more credible.

FAQ

Is organic matcha necessarily pesticide-free?

Not necessarily. The organic label prohibits synthetic pesticides, but it does not replace a direct analysis of the finished product. To know what is actually in the product, an independent laboratory test is required.

Can Japanese matcha be pesticide-free without being organic?

Yes. Some producers follow very clean practices without pursuing organic certification, largely because of its cost and the administrative burden it entails in Japan. The absence of a label does not, therefore, mean that good practices are not being followed.

Why does matcha deserve more attention than regular tea?

Because the entire leaf is consumed in powder form. Residue testing is therefore particularly important for this category. It’s a simple but crucial difference.

What is an independent pesticide residue analysis?

This test is conducted by an external, accredited laboratory that screens for the presence of chemical compounds (pesticides, herbicides, fungicides) in the matcha sample. Rigorous analyses test for several hundred compounds simultaneously. The results are expressed in mg/kg and compared to the maximum residue limits (MRLs) established by European regulations.

Is the Japanese JAS organic certification equivalent to the European organic label?

Both systems share the same basic principles (ban on synthetic pesticides, traceability), but their inspection procedures, costs, and levels of support for producers differ significantly. A JAS-certified product may be imported and sold as organic in Europe under certain conditions, but the two labels are not strictly identical in their implementation.

How can you tell if matcha is truly pesticide-free?

Look for three things: clear origins, independent testing, and true transparency in documentation. If the brand remains vague about its results, that’s a red flag.
