Why Kyoto Uji Matcha Is the Best in the World

In recent years, matcha has been produced not only in Japan but also in countries such as China and Vietnam. In other words, not all matcha comes from the same place.

Among them, Japanese matcha has earned an outstanding reputation worldwide.

In particular, Uji matcha, produced in Kyoto, has long been regarded as one of the finest matchas by tea masters, specialty cafés, and matcha enthusiasts.

But aren't all matchas basically the same?

Many people think so. In fact, very few consumers pay attention to where their matcha is produced.

So, let us ask you a simple question.

When you buy a bottle of wine, do you ignore where it was produced?

Even within France, wines from Bordeaux and Burgundy differ significantly in flavor, quality, and reputation.

The same is true for matcha.

The label Made in Japan does not automatically guarantee exceptional quality. Depending on where it is grown, matcha can vary dramatically in flavor, aroma, color, and even price.

Among Japan's many tea-producing regions, Uji Matcha from Kyoto has earned an exceptional reputation among world-class cafés, tea masters, and matcha lovers around the globe.

So why is Uji matcha considered so special?

In this article, you'll learn what matcha really is, why Uji became Japan's most famous matcha-producing region, how quality differs across Japanese growing areas, and how to identify authentic, high-quality Uji matcha.

What Is Matcha? How Is It Different from Green Tea?

You have probably heard the term green tea before.

While both matcha and green tea come from the same tea plant (Camellia sinensis), they are not the same.

They differ significantly in how they are grown, processed, prepared, and even how they taste.

Most standard green teas are made by steeping tea leaves in hot water to extract their essence.

Matcha, on the other hand, is made from specially cultivated leaves known as "tencha, which are ground into a fine powder.

As a result, matcha allows you to enjoy the full nutritional benefits of the tea leaves.

Feature	Matcha	Green Tea
Cultivation	Shade-grown	Usually grown in full sunlight
Raw Material	Tencha	Tea leaves
Preparation	Powder whisked into water	Leaves steeped in hot water
Tea Leaves	Entire leaf consumed	Leaves discarded after brewing
Flavor	Rich umami and natural sweetness	Refreshing, slightly astringent
Color	Bright, vibrant green	Pale yellow-green

As you can see, matcha and green tea may come from the same plant, but they are very different in both production and taste.

The tencha used for matcha is usually shade-grown for about three to four weeks before harvest.

This process helps increase L-theanine, the amino acid responsible for matcha’s rich umami and natural sweetness.

It also gives high-quality matcha its beautiful, vibrant green color.

In other words, matcha is not simply powdered green tea.

From cultivation and processing to grinding, each step requires skill, time, and careful craftsmanship.

One of the most important factors that affects matcha quality is where it is produced.

Depending on the region, matcha can vary greatly in flavor, aroma, color, and price.

Among Japan’s many tea-producing regions, Uji Matcha from Kyoto is especially known for its exceptional quality and global reputation.

Why Is Uji Matcha Considered the Finest in the World?

As global demand for matcha continues to grow, more countries—particularly across Asia—have begun producing their own matcha.

Yet despite the increasing number of producers, Uji Matcha from Kyoto, Japan continues to be regarded as one of the world's finest.

So, what makes Uji matcha so special?

The answer goes far beyond its place of origin. Uji's reputation has been built over centuries through a unique combination of history, natural growing conditions, and traditional craftsmanship.

Let's explore the three key reasons why Uji matcha has earned its world-class reputation.

1. Over 800 Years of Tea-Making Tradition

Uji is one of Japan's oldest tea-producing regions, with a history dating back nearly 800 years.

Tea cultivation began in the 1200s, and by the 1300s to 1500s, Uji had become Japan's premier region for high-quality tea.

As the Japanese tea ceremony evolved, Uji tea gained even greater prestige and eventually became recognized as Japan's leading tea-producing region.

Over the centuries, generations of tea farmers and artisans refined cultivation and processing techniques that continue to influence modern matcha production today.

Many of the traditional practices now associated with premium matcha—such as shade-growing tea plants and producing tencha, the raw material used to make matcha—were perfected in Uji.

The global reputation of Uji matcha is not simply the result of its long history.

It comes from centuries of continuous refinement, craftsmanship, and an unwavering commitment to quality.

2. An Ideal Environment for Growing Premium Tea

Exceptional matcha begins long before the leaves are harvested.

The natural environment plays a crucial role in determining the flavor, aroma, and color of the tea.

The Uji region is known for its large temperature differences between day and night and its frequent morning mist.

These conditions allow tea plants to grow slowly while developing higher concentrations of L-theanine, the amino acid responsible for matcha's signature umami and natural sweetness.

As a result, Uji-grown tea leaves develop a vibrant green color, a smooth texture, and a rich, well-balanced flavor.

Of course, Uji is not the only region in Japan that produces excellent matcha. Areas such as Kagoshima and Nishio also produce outstanding teas.

However, Uji's unique climate, combined with centuries of tea-growing experience, has helped establish it as one of the world's most respected matcha-producing regions.

3. Traditional Manufacturing Techniques Passed Down Through Generations

Producing high-quality matcha requires far more than harvesting excellent tea leaves.

After harvest, the leaves are steamed, dried, and carefully processed into tencha before being ground into an ultra-fine powder.

Among all of these steps, the grinding process is one of the most critical.

Traditionally, tencha is ground using a granite stone mill that rotates extremely slowly. A single stone mill produces only 30g to 40g of matcha per hour—roughly enough to fill one 30g tin.

Modern machinery can produce matcha much faster. However, high-speed grinding generates heat, which may affect the tea's color, aroma, and delicate flavor.

A stone mill, by contrast, minimizes heat while producing an exceptionally fine and uniform powder. This helps preserve matcha's vivid green color, fresh aroma, and smooth, creamy texture.

For this reason, the price of premium Uji matcha reflects far more than its famous name.

It also reflects the time, skill, and craftsmanship required to produce matcha without compromising quality—a tradition that has been carefully preserved for generations.

Not All Uji Matcha Is High Quality

Here's an important fact that many people don't realize: Not all Uji matcha is premium quality.

In Japan, Uji matcha is widely available for around €10 per 30g in souvenir shops, supermarkets. 

This often leads overseas buyers to assume that premium matcha is simply much cheaper in Japan. 

It is true that matcha sold domestically avoids international shipping, customs duties, and import costs. However, the low price of these products also reflects their quality. 

Truly premium matcha remains expensive even in Japan.

The same is true for wine.

Just because a supermarket sells wines from Bordeaux or Burgundy doesn't mean every bottle is a fine wine. The highest-quality wines are often produced in limited quantities and sold through specialty retailers, with significant differences in both quality and price.

Matcha is no different.

Even within Uji, the quality of matcha varies greatly depending on factors such as:

• Harvest season
• Tea cultivar
• Cultivation method
• Leaf selection
• Manufacturing process
• Grinding method
• Storage conditions

For example, matcha made from first-harvest tea leaves generally offers a richer umami flavor, brighter green color, and smoother taste than matcha produced from later harvests.

Likewise, matcha intended for the Japanese tea ceremony is held to very different quality standards than matcha produced for lattes or desserts.

To identify truly exceptional matcha, you should look beyond its origin and also consider the tea grade, harvest season, intended use, and production methods.

Origin matters—but it is only one piece of the puzzle. Truly exceptional matcha is the result of many factors working together.

Most Matcha Available in Europe Is Not Uji Matcha

In recent years, matcha has become increasingly popular across Europe. Today, it is easy to find products labeled Matcha, Japanese Matcha, or Premium Matcha in supermarkets and online stores.

However, not all of these products are made from authentic Uji matcha.

The reason becomes clear when we look at global matcha production.

Figure. Estimated share of global matcha production, Japanese matcha, and Uji matcha.

As shown in the figure above, the majority of the world's matcha is produced outside Japan. Japanese matcha accounts for only about 12% of global production.

Even within Japan, Kyoto Prefecture—the primary production area for Uji matcha—accounts for only about 23% of the country's tencha production.

This highlights just how rare authentic Uji matcha is.

In addition, premium Uji matcha is already in high demand within Japan, while production remains limited. Exporting it to Europe also involves strict food regulations, import duties, VAT, international shipping costs, and other logistical challenges.

Given these supply constraints,  it is unlikely that every matcha product sold in Europe is made from authentic Uji matcha.

Instead of relying on marketing terms such as Japanese Matcha or Ceremonial Matcha, look for products that clearly disclose essential information, including:

• Origin (country and region)
• Tea cultivars
• Milling method
• Producer or brand information

Brands that openly share this information demonstrate a higher level of transparency, allowing consumers to make more informed purchasing decisions.

Unfortunately, labeling requirements vary by country and sales channel, and many matcha products provide only limited information about their origin or production.

If you're looking for authentic Uji matcha, choosing a brand that clearly communicates where its matcha comes from and how it is produced is one of the best ways to purchase with confidence.
