What “Uji tea” officially means
In March 2004 the Kyoto Prefectural Tea Industry Council wrote the definition down. Uji tea, it says, is tea from four prefectures — Kyoto, Nara, Shiga and Mie — refined and finished by a Kyoto company inside Kyoto, with Kyoto-grown leaf given priority. The council has said the actual proportions cannot be published.
The route to that wording is the part I find worth knowing. A year earlier, in April 2003, a stricter rule had been tried: at least half the leaf from Kyoto, with any blending limited to Nara, Shiga and Mie. It was not adopted. There was not enough Kyoto leaf to go round, and the producers would not approve it. The definition in use today is what the industry could actually meet.
Uji is a finishing designation, not a growing one. The name tells you which prefecture refined the tea and by whose method — not which hillside it came off.
Kyoto is a small tea prefecture
This one surprised me. Japan produced 73,900 tonnes of crude tea in 2024. Kyoto produced 2,780 tonnes of it — fourth in the country, and about 3.8 percent of the total.
| Prefecture | Crude tea, 2024 |
|---|---|
| Kagoshima | 27,000 t |
| Shizuoka | 25,800 t |
| Mie | 5,020 t |
| Kyoto | 2,780 t |
| Miyazaki | 2,640 t |

Kagoshima grows nearly ten times what Kyoto grows. It also passed Shizuoka for the first time in the history of the statistic, largely by converting sencha fields to tencha — the leaf that becomes matcha. The centre of gravity of Japanese tea has moved south, and it moved recently.
Inside Kyoto, Uji grows almost none of it
Kyoto Prefecture publishes its own figures by town. In 2024 they looked like this.
| Tencha, 2024 | Tonnes | Share of Kyoto |
|---|---|---|
| Kyoto Prefecture | 1,057.0 | — |
| Wazuka Town | 549.3 | 52.0% |
| Minamiyamashiro Village | 151.6 | 14.3% |
| Ujitawara Town | 148.5 | 14.0% |
| Kizugawa City | 74.2 | 7.0% |
| Uji City | 37.6 | 3.6% |
Kyoto Prefecture survey, 2024 crop year. Autumn tencha excluded.
Wazuka, a town of a few thousand people in the hills at the southern edge of the prefecture, grows more than half of Kyoto’s tencha. Uji City grows about one fifteenth of what Wazuka grows. Much of Wazuka’s tea leaves the town through wholesalers and reaches the shelf as Uji tea. The tea travels; the name of the town mostly does not.
I want to be careful here, because it would be easy to read this as an accusation. It is not one. Nothing about this is hidden; the prefecture publishes the table. The tea is genuinely Kyoto tea, genuinely finished in Kyoto, by people who have been doing it for centuries. What has happened is simply that a place name outlived the geography it once described.
But Kyoto really is a tencha prefecture
Small in volume, yes. Specialised to an unusual degree, also yes. Of Kyoto’s 2,492 tonnes in 2024, tencha and autumn tencha together came to 1,648 tonnes — about two thirds. In money the concentration is sharper still: tencha accounted for roughly 77 percent of the prefecture’s tea revenue.
The first-flush price tells you why.
| First flush, 2024 | Yen per kg |
|---|---|
| Sencha | 3,624 |
| Kabusecha | 3,675 |
| Gyokuro | 5,527 |
| Tencha | 7,356 |

Tencha trades at about twice sencha. A prefecture with steep, small, hard-to-mechanise fields cannot win on tonnage, so it competes on the one tea where care is worth the most per kilogram. Read that way, Kyoto’s smallness and its reputation are not in tension. They are the same decision.
What Uji did invent
If the name no longer describes a field, it does describe something. Two things, in fact, and both of them changed Japanese tea permanently.
The first is shading. In the sixteenth century, growers in Uji began covering their fields with screens woven from reed cut at Ogura Pond, which then lay between Uji and Kyoto. Blocking the sun holds back the bitterness and pushes the leaf towards a deep green and a heavier sweetness. That covered leaf, steamed and dried without rolling, is tencha. Ground, it is matcha. The tea that the whole world now drinks in lattes began as a request from tea masters for something less astringent.
That method has not entirely become an industrial one. In the Shirakawa district of Uji City, fields are still covered with natural reed — honzu, the original form — rather than the synthetic cloth used almost everywhere else.
The second invention came later and from the next valley. In 1738, in the hamlet of Yuyadani in Ujitawara, a farmer named Nagatani Soen worked out a way of steaming and rolling leaf that produced a clear green infusion instead of the dull brown that ordinary tea gave at the time. That method — aosei sencha seiho — is the ancestor of essentially all Japanese sencha and gyokuro made today. Ujitawara now farms about 260 hectares of tea across roughly 80 households, and calls itself the birthplace of Japanese green tea. On the numbers above, it also grows four times more tencha than Uji City does.
Uji’s claim is not that it grows the most. It is that shading and the sencha method were both worked out here, and the steamed-leaf tea most of Japan makes today still follows them.
The cultivars, and why they matter on a tin
Kyoto Prefecture names three cultivars as its main ones for tencha: Asahi, Samidori and Ujihikari. All three are picked by hand, which is the expensive way and, on those slopes, often the only way.
Samidori has a documented parentage worth knowing: it was selected from native Uji seedlings and bred at the prefectural tea research station in 1954. Later, as machine picking spread, the same station bred Tenmyo specifically for it, registering the cultivar in February 2006.
Here is the practical part. Ceremonial-grade matcha is normally a blend, and a blend has no cultivar name. So when a shop does put a cultivar on the tin — Samidori, Asahi, Okumidori — it is telling you it knows its supply chain well enough to keep one cultivar separate. That is a real signal, and it costs the seller something to give you. It does not automatically mean the tea tastes better than a good blend. It means someone made a decision and is willing to be held to it.
What I would ask before buying
None of this makes Uji matcha worse. It makes the word less informative than it looks, which is a different thing. Three questions get you most of the way past it.
Where did the leaf grow? Not the prefecture — the town. Wazuka, Ujitawara, Minamiyamashiro. A seller who knows will tell you happily.
Is it a single cultivar or a blend? Either answer is fine. A vague answer is the informative one.
When was it milled? Matcha fades. This has nothing to do with Uji, and it will affect your bowl more than the place name will.
→ If you are still deciding what to buy at all, start with how to make matcha properly and the bowl and whisk you actually need.
→ Several shops on the Matcha Atlas name Uji on their menu — TSUJIRI, JENKI and Nippon Cha among them. The Atlas records what each one publishes about its tea.
What I take from it
I grew up with the assumption that Uji was where matcha came from. Reading the prefecture’s own table was genuinely odd — the town on every tin, sitting fifth on the list, at 3.6 percent.
What survives the numbers is not the geography. It is the method: covering the field, steaming without rolling, grinding slowly on stone. Uji worked all of that out, and then the method left with anyone who wanted it. The name on the tin is really the name of a technique, and a technique can be carried up the valley to Wazuka, or south to Kagoshima, without becoming any less itself.
That is, I think, a better thing for a place to be famous for than a postcode.
Frequently Asked Questions
Does Uji matcha have to be grown in Uji?
No. The 2004 definition allows leaf from Kyoto, Nara, Shiga and Mie, refined by a Kyoto company inside Kyoto, with Kyoto-grown leaf given priority. The proportions are not disclosed.
Which town grows most of Kyoto’s tencha?
Wazuka — 549.3 of Kyoto’s 1,057.0 tonnes in 2024, about 52 percent. Uji City grew 37.6 tonnes, about 3.6 percent.
Is Kyoto Japan’s largest tea producer?
No. It was fourth in 2024 at 2,780 tonnes, roughly 3.8 percent of the national crop. Kagoshima was first at 27,000 tonnes.
Which cultivars does Kyoto grow for tencha?
Asahi, Samidori and Ujihikari, all hand-picked. Tenmyo was bred later for machine picking and registered in 2006.
What is honzu?
Shading with screens of natural reed rather than synthetic cloth — the original sixteenth-century method, still used in the Shirakawa district of Uji City.
