The name was decided at a meeting in 1925
Before 1925 the tea of this part of Fukuoka went by several names — Chikugo-cha, Kasahara-cha, Hoshino-cha — depending on which district it came from. At a national tea competition held that year in what is now central Yame City, the head of the Fukuoka tea association, Hisakichi Konomi, proposed replacing all of them with one name: Yame-cha. The members voted for it unanimously.
So the most protected name in Japanese tea is a hundred years old and was created by committee. That is worth sitting with for a moment, because the same thing turned up when I looked at Mori, where the town’s reputation was built by a ballad commissioned in the 1930s. Two of Japan’s tea names that feel most traditional from the outside were, in fact, deliberate modern branding.
The tea is old. The name is not. In Japanese tea those are separate facts, and the second one is usually a twentieth-century decision.
What Yame protects now
Having settled on one name, the region has since registered it more thoroughly than anywhere else I have looked at.
| Protection | Covers |
|---|---|
| Yame-cha | Regional collective trademark |
| Fukuoka no Yame-cha | Regional collective trademark |
| Yame Matcha | Regional collective trademark |
| Yame Dento Hon Gyokuro | Geographical Indication no. 5 |
Japan Patent Office; Ministry of Agriculture, Forestry and Fisheries, GI register.
For comparison, Shizuoka — the second-largest tea prefecture in the country — has four registered tea names across the whole prefecture. Yame has three for one area, plus the GI.
The GI, and what it actually requires
Japan’s Geographical Indication system began in 2015. Yame Dento Hon Gyokuro was registered that December as number 5, and it was the first tea in the country to receive one.
What the registration protects is a method, written down in unusual detail. The ministry’s entry lists it plainly: shading with natural materials such as rice straw on a raised frame, naturally trained bushes rather than clipped hedges, and hand picking — practices it says have been kept for more than 110 years. Yame City dates the start of gyokuro production there to 1904, which is where that number comes from.
Almost all Japanese tea is trained into the rounded hedges you see in photographs, because a machine has to be able to run along the top of them. Naturally trained bushes are left to grow as they will, which makes machine picking impossible and hand picking the only option.
Shading runs for about twenty days over the first flush, with straw laid on a frame above the bushes rather than cloth on the bushes themselves. Blocking light holds back the astringency and lets the leaf build the amino acids that carry sweetness and umami — the same principle behind tencha at Uji, applied to a leaf that will be rolled rather than ground.
Two different things are called gyokuro
This is the part I most want to get across, and it took comparing two government figures to see it.
The Ministry of Agriculture, listing the leading prefecture for each type of tea, gives gyokuro to Mie, at 74 percent of national production. Yame, meanwhile, has taken the regional prize for gyokuro at the national tea competition for over twenty consecutive years, and the traditional grade has won the minister’s award repeatedly.
Both are true. They are describing different things.
| Gyokuro by volume | Yame Dento Hon Gyokuro | |
|---|---|---|
| Where | Mainly Mie | Hill districts around Yame |
| Shading | Commonly synthetic cloth | Rice straw on a raised frame |
| Bushes | Trained hedges | Naturally trained |
| Picking | Largely mechanical | By hand |
MAFF for the production share; MAFF GI register and the Fukuoka tea council for the traditional grade’s requirements.
I want to be careful here, because it would be easy to turn this into a ranking and that would be wrong. Mie’s gyokuro is gyokuro. It meets the standard for the category, it is made well, and most people who have enjoyed gyokuro have been drinking something made at that scale. The point is not that one is real and the other is not. The point is that a single word is doing two jobs, and a shopper outside Japan has no way to tell which one is in the tin unless the seller says.
How many people make it
The traditional grade is small and getting smaller. Fukuoka’s agricultural cooperative put the number of producers at around 180 in 2015 and around 140 more recently, and the reason its own tea division gives is straightforward: bottled tea has replaced the teapot in most households, and a tea that only makes sense brewed carefully loses its occasion.
Against that, the wider picture in Fukuoka is stable.
| Fukuoka Prefecture | Figure | National rank |
|---|---|---|
| Crude tea production | about 1,870 t | 6th |
| Area under tea | 1,540 ha | 5th |
| Share of that area in the Yame region | about 90% | — |
Fukuoka Prefectural Tea Industry Promotion Council. Production has moved between roughly 1,700 and 2,300 tonnes over the past decade.
Gyokuro and tencha come from the hills — Kurogi, Joyo and Hoshino — where the day-to-night temperature swing brings morning mist and the leaf builds umami slowly. The flatter land makes sencha.
And then the country registered itself
On 10 July 2026 the Ministry of Agriculture registered three new Geographical Indications. Two were what you would expect: eel from Lake Hamana, lotus root from Kaga. The third was Nihoncha — Japanese tea — with the production area given as Japan.
It was the first registration to name the whole country as the place, and it brought Japan’s total to 170 registered products.
I find the sequence striking. In 2015 one set of hill farmers in Fukuoka registered a method they had been keeping since 1904, and became the first tea in Japan to be protected that way. Eleven years later the country did the same thing for the entire category, against the rest of the world.
What this means when you buy
Yame-cha means Fukuoka. The trademark covers tea from the prefecture, grown mostly in the Yame region. It does not tell you the grade.
Yame Dento Hon Gyokuro means the method. Straw shading, naturally trained bushes, hand picking, from the hill districts. That is a much narrower promise, and about 140 households stand behind it.
If a tin says only “gyokuro”, it is telling you the category and nothing else. That is not a warning — it is simply the limit of the word. Ask where it grew and how it was shaded.
→ The rest of this series: Uji, Nishio, Mori, Kagoshima and Ise.
What I take from it
Four regions in, the pattern is clearer than I expected when I started.
| Name | What it guarantees |
|---|---|
| Uji | Finished in Kyoto. Leaf may come from four prefectures |
| Nishio no Matcha | Grown, processed and milled in the same two cities |
| Mori no Cha | Nothing. No registration exists |
| Yame Dento Hon Gyokuro | A written method, protected nationally since 2015 |
None of these names is dishonest. Each was written by different people, at a different time, to hold a different thing together. What surprised me is how recent the writing is: 1925 for the name Yame-cha, 2015 for the GI, 2019 for the Kakegawa boundary that includes Mori, 2004 for the Uji definition. The tea is centuries old; almost all the rules around the names were written in living memory.
Which is, I think, encouraging. Rules written recently can be written again. The 140 households shading their bushes with straw are not preserving something fixed — they are the reason there is anything to write a rule about.
Frequently Asked Questions
Where is Yame tea from?
Yame City and around it, in southern Fukuoka on Kyushu. Fukuoka has 1,540 hectares of tea, fifth nationally, about 90 percent of it in the Yame region.
What is Yame Dento Hon Gyokuro?
A protected grade: rice-straw shading on a raised frame, naturally trained bushes, hand picking, from the hill districts. Geographical Indication no. 5, registered December 2015 — the first tea in Japan to get one.
Is Yame the largest producer of gyokuro?
Not by volume. The ministry puts Mie at 74 percent of national gyokuro. Yame’s standing rests on the traditional hand-made grade.
How old is the name Yame-cha?
It dates from 1925, when the head of the Fukuoka tea association proposed replacing several district names with one, and the members agreed unanimously.
Is Japanese tea itself protected as a GI?
Yes, since 10 July 2026, with Japan given as the production area — the first registration to name the whole country.
