Japan

A green-tea producer almost exclusively, distinguished by steamed fixation, extensive shading and a highly mechanised, quality-controlled supply chain.

Production, trade and price

Measure	Year	Value	Basis	Published by
Harvested area	2023	36,000 ha	FAOSTAT QCL element 'Area harvested' for item 667 / CPC 01620 'Tea leaves', in hectares. FAO's methodology note warns that for permanent crops such as tea 'data may refer to total planted area' rather than area actually harvested, so this is the area under tea and not necessarily the area picked in the year. The associated crop is measured as green leaf. FAOSTAT flags this cell A, an official figure reported by the country.

Production	2023	320,000 t	FAOSTAT QCL element 'Production' for item 667 / CPC 01620 'Tea leaves', in tonnes. FAO's QCL methodology note states the domain 'contains production data for primary products', so this counts GREEN LEAF as plucked, not made tea. It is roughly four to five times the made-tea figure the same country's tea board publishes. FAOSTAT flags this cell A, an official figure reported by the country.	Food and Agriculture Organization of the United Nations (FAO), Statistics Division
Yield	2023	8,889 kg/ha	FAOSTAT QCL element 'Yield' for item 667 / CPC 01620 'Tea leaves', in kilograms per hectare, computed by FAO from the production and area figures rather than reported directly. Because production is GREEN LEAF and the area may be planted rather than harvested, this is green-leaf yield per hectare planted and is not comparable with a made-tea yield. FAO states that yields of permanent crops 'are not as reliable as those for temporary crops'. FAOSTAT flags this cell A, an official figure reported by the country.

Figures are reproduced as their publisher stated them and are not converted, averaged or ranked. Where two publishers disagree, both rows appear — this comes from Food and Agriculture Organization of the United Nations (FAO), Statistics Division. The largest single trap in tea statistics is that FAO’s series counts green leaf as plucked while national tea boards count finished made tea, and the two differ by roughly a factor of four and a half. The basis column says which each row is, and a figure without it is not comparable to one with it.

How TeaHQ handles sources

How production is organised

Small family farms and a processing split that most foreign buyers never see. Growers generally make aracha — crude tea, steamed, rolled and dried — and sell it on to a merchant or co-operative that fires, sorts, cuts and blends it into the finished product. The consequence is that a Japanese tea's character is set twice, once in the field and once in the blending house, and that a prefecture name on a packet frequently describes where the blending happened rather than where all of the leaf grew.

How firm this is: Inferred by TeaHQ from general knowledge of the trade rather than taken from a source that states it.

What it produces

Overwhelmingly green tea. Steaming rather than pan-firing is the standard fixation method, giving the characteristic marine, umami-forward profile; shading before harvest is used deliberately to raise that character further.

What it is known for

The categories this country is most associated with. Being known for a category is a fact about reputation and volume rather than about quality.

Green tea — Tea whose oxidation is halted early by heat, keeping the leaf green and the cup fresh, vegetal or marine in character.

Growing regions in Japan

Named districts with their own elevation, climate and character. Elevation figures are recorded as ranges because sources disagree on where a district begins and ends.

This country in the chronology

Events on TeaHQ’s timeline that happened here or turned on this country. Each carries its date together with what kind of date it is.

Early ninth century — Tea reaches Japan the first time, and does not take
Returned from China c. 1191; wrote Kissa Yōjōki in the early thirteenth century — Eisai, and what he actually did
From around the sixteenth century — Uji starts shading the bushes
Across the sixteenth century, ending with Rikyū's death — Sen no Rikyū and the small room
Traditionally 1610, with Portuguese contact earlier — The first tea cargoes reach Europe
The technique matures across the Edo period and is mechanised in the twentieth century — Tencha, the stone mill, and why matcha is expensive
The eighteenth century — Senchadō, and the monk who sold tea in the street
Canned oolong from 1981; canned unsweetened green tea from 1985 — Japan puts unsweetened tea in a can
From the 2000s, with acute supply pressure from the mid-2020s — The matcha boom, and the shortage it produced

How its tea is graded

Japanese classification names the tea by its cultivation and processing (sencha, gyokuro, bancha, kabusecha) rather than by leaf size. It has no relationship to Indian leaf-grade abbreviations.

Grading conventions do not translate between countries. The same abbreviation can describe leaf size in one origin and picking standard in another, and TeaHQ records each system on its own terms rather than mapping them onto a common scale.

How tea is drunk here

Home to chanoyu, the Japanese tea ceremony — a living practice with its own schools and lineages, described on TeaHQ from the outside and attributed accordingly.

Guides covering this origin

Refrigerating and freezing tea: when it genuinely helps and when it is a mistake — Cold storage is standard commercial practice for Japanese green tea and a reliable way to ruin several other categories. The difference is not the temperature — it is condensation, odour and whether the tea was supposed to keep changing.
Yield, mechanisation and the labour economics behind them — Plucking is the largest recurring labour cost in tea and the hardest to mechanise without changing the product. Everything about how tea fields are laid out, pruned and harvested follows from that tension.
Kuradashi: the one Japanese green tea tradition built on keeping it — Japanese green tea is the category most defined by freshness, and it also has an established practice of holding tea in cold store from spring and releasing it in autumn as a distinct product. The two are not in contradiction, and the reason is instructive.
Reading a Japanese tea label, field by field — Japanese packaging is the most informative in common circulation and most of it never reaches an English-language listing. The product name, the picking, the prefecture, the steaming depth and the cultivar are usually all present, and each of them narrows what the tea can be.
Japan received tea twice, and the first time did not take — Tea reached Japan with Heian-period monks and court contact several centuries before the transmission everybody credits, and then largely lapsed. Understanding the gap explains why Japanese tea culture is built on Song practice rather than on Tang practice.
Japan’s tea export industry, and why it collapsed — For several decades after the ports opened, tea was one of Japan’s two great exports and the American market was its destination. Then the product was reformulated for that market, discredited, and displaced — and Japan turned inward, which is why it now exports so little.
Which countries grow tea — Around fifty countries grow tea commercially and four of them account for most of it. The more useful split is not who grows the most but who exports, who drinks their own, and who does something neither of those numbers shows.
Does the growing region change the taste? — Yes, and much less directly than the word terroir implies. Most of what a reader attributes to place turns out on inspection to be cultivar and processing — both of which travel with the place, and neither of which is the place.
Hand-picked and machine-harvested tea — How a field is harvested decides how uniform the leaf is, which decides how the tea can be processed and what it can become. It is also a labour-cost decision, and the two are the same decision.
Buying single-cultivar tea — A cultivar name on a packet is a producer's decision made visible, not a grade. It tells you something real and it does not tell you the tea is better — and the words cultivar, variety, clone and landrace are four different things that packaging routinely mixes up.
