Disclosure: some links here are affiliate links — buy through one and a small commission comes my way, while your price stays exactly the same. Nobody sent me free tea. The figures below come from Japanese government statistics, auction reports and industry documents I read in Japanese, listed with links at the bottom; the few taken from trade reporting are flagged in the text.
There’s a version of this story going around that says a lot of people saw matcha on TikTok, bought it all, and now there’s none left. That’s not wrong, exactly. It’s the last five percent of the explanation.
The other ninety-five percent: Japan has been quietly running out of tea farmers for thirty years, the one kind of tea the world suddenly wants is the most labour-intensive thing a Japanese farm can produce, and the machines that turn it into powder have a waiting list. Demand arrived in about eighteen months. Supply moves on a five-year clock, minimum.
I live here, and I’ve watched the purchase-limit signs go up in my neighbourhood tea shop and stay up. I’ve also spent the last few weeks reading the actual numbers — Ministry of Agriculture crop statistics, a National Diet research paper on matcha supply, auction results from the Kagoshima and Kyoto exchanges, a Bank of Japan price index — because almost nothing written about this shortage in English cites anything at all. Figures verified between 1 and 4 August 2026, and rechecked on 20 August.
Who This Article Is NOT For
Three groups can save themselves twenty minutes.
- If you just want to know where to buy some. Different job, done separately: my guide to where to buy authentic ceremonial matcha online has current per-gram prices, live stock checks and purchase caps for six sellers. This piece is the why, not the where.
- If you want to know whether “ceremonial grade” is real. Short answer, no — there’s no official grading system anywhere, and that same guide unpacks the Japanese naming conventions that replace it.
- If you’re hoping prices go back to 2023 levels. They don’t. I’ll show you why the floor is structural rather than speculative.
What Actually Ran Out Is Tencha, and There Was Never Much of It
Matcha is not a plant. It’s a process. The raw material is tencha — leaf shaded from sunlight for weeks before picking, steamed, then dried flat without being rolled, de-stemmed, and milled to powder. Everything upstream of the mill is a different crop from ordinary green tea, grown differently, harvested differently, processed in a purpose-built facility.
Here’s the number that reframes the shortage. In 2024, Japan produced 5,336 tonnes of tencha out of roughly 75,000 tonnes of crude tea. Tencha is 7.3% of Japan’s tea. That share has grown fast — 4.2% in 2021, and output roughly tripled in a decade — but it grew from a rounding error. When global demand for one product jumps by multiples and that product is one-fourteenth of national output, you don’t get a price rise. You get a market failure.
And the base is shrinking. Japan’s tea-planted area went from 48,700 hectares in 2005 to 33,400 in 2025, down 31%; crude tea output from about 100,000 tonnes to 75,100, down 25%. The matcha boom is a fast-expanding slice of a steadily shrinking pie.
Cause One: There Are Almost No Tea Farmers Left
This is the part nobody outside Japan talks about. The Agriculture Ministry’s census counts core agricultural workers — people whose main job is their own farm. For tea:
- 2010: 25,043 people
- 2015: 17,894 people
- 2020: 11,644 people
More than half gone in a decade, and of the 11,644 still standing in 2020, 73.8% were 60 or older. The same census counted 12,929 tea-growing farm businesses in all of Japan — 5,827 in Shizuoka, 1,281 in Kagoshima, and just 506 in Kyoto, the prefecture whose name sells more matcha worldwide than any other. Five hundred and six. That’s the grower base the global “Kyoto matcha” trade rests on.
The bushes are ageing too: 39.6% of Japan’s tea gardens carry bushes over 30 years old as of fiscal 2024, against an economic life of 30 to 50 years. Replanting is the fix, subsidised since 2011 — cumulatively 6,452 hectares by fiscal 2024, about a fifth of the national area. It hasn’t kept pace.
There’s a geography problem on top. About 40% of Japanese tea gardens sit in hilly terrain where machines struggle. Nationally 70.2% of growers use riding harvesters; in flat Kagoshima it’s 98.1%, in steep, terraced Kyoto 21.4%. Labour runs 83 hours per 10 ares on slopes versus 39 on flat ground. Which is why Kagoshima, not Kyoto, is where new capacity is going — in 2025 it produced more first-flush crude tea than Shizuoka for the first time in the history of the survey.
Cause Two: Shading Is the Hardest Job on the Farm and Nobody Has Mechanised It
To make tencha you cover the bushes — traditionally reed screens and straw over a wooden frame, now often synthetic cloth — for weeks before picking. The shade drives up chlorophyll (that’s the colour) and suppresses the breakdown of the amino acids that give matcha its sweetness and umami.
It is also brutal work. Ministry field surveys put covering at 18% of total field labour hours — tied for the single biggest job on a tea farm, level with picking and trimming. And it has resisted mechanisation, because fixing material down against wind is fiddly, physical and site-specific. Japan’s smart-agriculture policy framework, adopted under a 2024 law, targets practical labour-saving covering technology by fiscal 2030. That’s the official timeline. Not next season. 2030.
Meanwhile the inputs got expensive. The agricultural vinyl price index went from 88 in 2011 to 135 in 2025, and fuel and utilities for a tea operation ran ¥39,977 per 10 ares in 2019 against an estimated ¥55,850 in 2025. That all comes out of a grower’s margin before a single leaf is picked.
There’s one more trap. Japan’s dominant tea cultivar is Yabukita — over 60% of national planted area, 88% in Shizuoka, 53% in Kyoto. Yabukita is a sencha cultivar, and under shade its chlorophyll response is sluggish and the bush takes real stress. Better tencha cultivars exist — Seimei was registered in 2020 — but in 2023 Seimei covered 130 hectares, 0.4% of Japan’s tea area. So “switch to matcha” for most farms means replanting, not just recovering.
Cause Three: Even If You Have the Leaf, You Can’t Get It Ground
This is the bottleneck almost nobody mentions, and the one I find most convincing.
Tencha needs a dedicated first-stage line — the steaming and drying regime differs from sencha, and preserving green colour needs specific kit. A National Diet research paper from December 2025 notes that over ten years, fiscal 2015 to fiscal 2023, government support programmes helped install 45 tencha processing facilities nationwide. Forty-five. Industry reporting puts one facility in the hundreds of millions of yen.
Then milling. A traditional granite tea mill produces roughly 40 grams of matcha per hour. An industrial grinder making comparably fine powder does about 20 kilograms per hour — a five-hundred-fold difference that explains both the price of stone-ground matcha and why so many products claim it.
Grinding capacity is now tight enough that, per Nikkei reporting cited in that Diet paper, some tea merchants have been investigating whether they can outsource milling to flour companies outside the tea industry entirely. When your supply chain starts phoning bakeries, it’s not a demand blip.
Why “Just Grow More” Doesn’t Fix This by Next Spring
Japanese tea runs on flushes. Ichibancha — first flush, picked late April through May depending on latitude — is the year’s premium crop and effectively the only one that becomes good drinking matcha. Nibancha in June and later pickings go to bottled drinks, blends and food-processing powder. Over 2020–24 the national average crude tea price ran about ¥1,808/kg for first flush, ¥734 for second, ¥422 for third. The value sits in a window a few weeks long, once a year.
So the clock: converting to matcha needs shade structures, often a replant to a suitable cultivar, and access to a tencha line. Replanting means roughly five years before a stable harvest, five of them with no income from that block. Even with money and will, the first commercially meaningful tencha from a conversion decided in 2026 lands around 2030 or 2031.
That’s the whole answer to “why doesn’t Japan just make more.” It is making more, and has been for a decade. The demand curve moved faster than a tea bush grows.
What the Prices Actually Did
Here are the 2026 opening auctions, the ones that set the tone for the year:
| Market | First auction 2026 | Opening price | Year on year |
|---|---|---|---|
| Kagoshima Tea Exchange | 6 April | ¥6,573/kg | +58.9% |
| Shizuoka Tea Market | 20 April | ¥9,019/kg | −14.0% |
| JA Zen-Noh Kyoto Uji-cha centre | 24 April | ¥20,879/kg | +22.1% |
Kagoshima up nearly 60% on a year that was itself a record. Kyoto up 22% from an already extreme base — and a Kyoto opening lot clears at over three times the Kagoshima price, which tells you how much of what you pay for “Uji” is the name. Shizuoka’s decline isn’t relief: it’s the sencha heartland, and sencha is having a different year.
Zoom out and it’s uglier. The 2025 first flush, per Ministry statistics published in August 2025, came in at 20,000 tonnes of crude tea, down 10% year on year, from a picked area of 22,300 hectares (down 5%) and a yield of 461kg per 10 ares (down 6%). Less area, less yield, less tea, into the sharpest demand in living memory. The Bank of Japan’s corporate goods price index for crude tea hit 164.1 against a 2020 base of 100.
The Collateral Damage Nobody Mentions
Because tencha pays roughly 2.7 times what sencha pays — ¥3,278/kg versus ¥1,197/kg in 2024 — growers moved. Sencha’s share of production fell from 54.0% in 2021 to 49.7% in 2024 while tencha’s rose from 4.2% to 7.3%.
So Japan’s everyday tea got expensive. In August 2025 the sencha crude tea price index sat at 101.8, more than three times its five-year average for that month. At the Shizuoka market in fiscal 2025, autumn-winter bancha — the cheapest, roughest tea of the year, destined for plastic bottles — traded at ¥2,097/kg, roughly seven times its recent norm and more than that season’s first flush. The price structure of Japanese tea inverted.
That’s why Ippodo restricted its bancha range from 1 March 2026, discontinuing the 200g bags of premium hojicha and genmaicha outright. Its own notice does the explaining: Kyoto’s 2025 first flush traded at 2.5 times the previous year’s average, machine-picked Kyoto tencha at ¥14,141/kg against ¥1,225 for bancha. It isn’t that everyone suddenly wants roasted twig tea. It’s that the leaf which used to become roasted twig tea is worth more as something else.
And people are going out of business anyway. Teikoku Databank counted 13 tea-processing companies closing or dissolving in 2025 plus one bankruptcy — 14 exits, the most on record. In a boom year. Their reading: sencha-based firms got squeezed between input costs they couldn’t pass on and demand that had moved to a product they weren’t equipped to make. Of roughly 300 processors surveyed for fiscal 2024, 42.7% grew profits and over half saw performance deteriorate.
The Yen and the Tariff: Two Things That Should Have Helped You, and Barely Did
If you’re buying from the US, two things moved in your favour recently. The tariff went away: green tea imported under HTS 0902.10 carried a 15% reciprocal tariff until an executive order exempted a batch of agricultural goods effective 13 November 2025, restoring it to 0%. And the yen is weak — about ¥163.9 to the dollar on 28 July 2026, near ¥157.8 on 4 August.
Your matcha still costs more than it did in 2023. A 15% tariff removal and a few percent of currency movement are rounding errors against auction lots that rose 59% in a single year and a leaf market that repriced by multiples. Currency and trade policy are noise here. The crop is the signal.
The same asymmetry shows in the trade data. Green tea exports in 2025 hit ¥72.1 billion, up 98.2% year on year — a sixth consecutive record — on 12,612 tonnes, with 69% of the volume and 84% of the value in powdered tea. Powdered exports went from 2,375 tonnes in 2020 to 8,718 in 2025. In the first quarter of 2026 they rose another 20.7% — while Japan’s green tea imports in the same quarter rose 2.4x, mostly from China.
How Mislabelled Matcha Actually Gets Made
That import figure is the hinge. Here’s the mechanism, which is less “criminal conspiracy” and more “a series of legal gaps you can drive a truck through.”
Gap 1: the definition of matcha isn’t law. The Japan Tea Central Association defines matcha as tencha — shade-grown leaf dried without rolling in a tencha furnace — milled to fine powder with a tea mill. Sound definition. It also has no legal force. Under it, second-flush or autumn leaf, covered by throwing cloth straight over the bushes rather than on a frame, machine-cut and pushed through an industrial grinder, is properly food-processing tencha, not matcha. In a tin, it is very often just called matcha.
Gap 2: “Uji” is broader than you think. The definition set by the Kyoto Prefectural Tea Industry Council in 2004 says Uji-cha is tea from Kyoto, Nara, Shiga or Mie prefectures, finished within Kyoto Prefecture by a Kyoto business, with Kyoto-grown leaf prioritised — and no published minimum percentage. That’s a legitimate historical trade definition, not a scam. But “Uji matcha” doesn’t mean “grown in Uji,” and outside Japan it’s routinely sold as though it does.
Gap 3: origin labelling stops at the border. Tea packaged for sale in Japan must carry, by law, the raw material’s origin, the country of origin for imports, a best-by date and the responsible business’s name and address — with an exemption when the labelable surface is 30 cm² or less. Export-only packaging doesn’t inherit those obligations. A tin sold solely overseas can carry a Japanese-sounding brand, a photo of a bamboo whisk, the words “ceremonial” and “stone-ground,” and no verifiable origin statement anywhere on it, entirely legally.
Gap 4: the substitute supply genuinely exists. China produced 89% of the world’s green tea in 2023 (2.17 million tonnes; Japan’s share, 3.5%). One factory in Tongren, Guizhou — built in 2017 with expertise brought in from Japan — has a stated matcha capacity of 4,000 tonnes a year. Guizhou’s provincial plan for 2026–2028 targets over 13,000 hectares of matcha gardens and more than 8,000 tonnes. Japan’s entire tencha output in 2024 was 5,336 tonnes, and reporting suggests China’s 2025 matcha production already passed 5,000.
None of that is illegitimate — Chinese matcha is a real product with real buyers, and some of it is good. The problem is what happens when a shortage of Japanese matcha meets an abundance of powder that can be labelled ambiguously. Which is exactly why, on 10 July 2026, Japan’s Agriculture Ministry registered “Japanese Tea” (日本茶) as a protected Geographical Indication — the first GI in the system whose production area is the entire country, enforceable through mutual recognition with the EU and UK. It is also a national-level admission that the prefecture-level brands weren’t holding the line.
Six Checks That Take Thirty Seconds
Not a taste test — I’m not making claims about tins I haven’t opened. These are things you can verify from a product page or a photo of the label.
| What to look at | Reassuring | Worth a second look |
|---|---|---|
| Origin statement | Named prefecture, town or producer, in Japanese as well as English | “Product of Japan” alone, or a Japanese-sounding brand with no address |
| Flush | Explicitly first flush / 一番茶, with a harvest year | No harvest information anywhere |
| Milling | “Stone-ground” alongside a plausible price and small tin sizes | “Stone-ground” on a 1kg bag at a supermarket price |
| Date | A best-by date roughly 6–12 months out, or a stated production date | A best-by 2+ years out, or none given |
| Colour in the photo | Saturated jade | Any reddish or brownish cast |
| “Uji” | Paired with a named Kyoto producer | Used alone as a quality claim |
Two of those need explaining.
The date. Matcha does not keep. Yamamasa Koyamaen, a Uji producer, guarantees eight months unopened, and only because their tins ship sealed with an oxygen absorber. Once heat, damp, light or air get in, the ooika — the distinctive shading aroma — turns musty and the powder takes on a reddish tinge. That reddish cast is the most useful visual tell there is, and it’s a different fault from the olive-green of sun-grown leaf. A very long best-by date on matcha isn’t stability; it’s a sign that whoever set it isn’t thinking about the tea.
The stone-ground claim. At 40 grams an hour per mill, a tonne of genuinely stone-ground matcha represents 25,000 mill-hours. Do that arithmetic on any large, cheap product making the claim. This isn’t a moral judgement on grinder-milled powder — modern shear-based mills produce excellent, consistent product for lattes and baking — it’s that the phrase does marketing work far more often than descriptive work.
What the Kyoto Purchase Limits Actually Mean
The rationing you’ve read about — two tins per customer, no 100g packs, a handful of items per order — is neither theatre nor scarcity marketing.
A Kyoto house like Ippodo or Marukyu Koyamaen buys contracted leaf from a small, named set of growers, blends to a house style, and sells under names that have to taste the same as last year. Supply is fixed by contract and by those 506 Kyoto tea businesses. Demand is now global and effectively unbounded. When you can’t buy more input and won’t compromise the blend, the only lever left is limiting output per customer.
Capping at 20g and 40g tins rather than raising prices to clear the market is also a choice about who gets the tea: it keeps someone walking in off the street on roughly equal footing with a bulk buyer, and it’s the bluntest available tool against resale. Read the caps as a leading indicator. When they loosen, supply is genuinely recovering. As of August 2026, they haven’t.
What Happens Next
Through 2027: no relief. The 2026 crop is in and it priced up, not down. New shade structures and tencha lines commissioned this year add capacity only at the margin, and retail is still catching up to wholesale as older inventory cycles out.
2028 to 2030: conversions decided in 2024 and 2025 start producing at scale, mostly in Kagoshima and Kyushu. If labour-saving covering technology hits its fiscal 2030 target, the cost structure improves. That’s the realistic window for a better supply picture — though Shizuoka Prefecture’s own long-run planning projects Japanese green tea demand near 80,500 tonnes against supply near 64,900. Structurally short, indefinitely.
China isn’t really a wildcard. Guizhou’s targets, if met, put more matcha in the world than Japan makes. The likely outcome is a split market: Japanese matcha as an explicitly premium, provenance-verified product with GI protection behind it, and the global latte-and-baking tier served by Chinese powder at a fraction of the price. Drink matcha from a bowl and you’ll pay more and know more about where it came from. Drink it with oat milk and you may not notice anything.
What I’d do as a buyer: stop chasing prestige names that are permanently sold out, buy 20 or 30 grams at a time so it doesn’t die in your cupboard, and pay attention to Kagoshima, where the new capacity actually is. For seller-by-seller specifics — stock, per-gram prices, which shops cap you — that’s my guide to buying authentic ceremonial matcha online. If you want one tin from a named Japanese producer shipping from a US warehouse without a 2am restock alarm, the Kyoto-made Maiko no Cha Honpo tin at Bokksu is a 20g tin: $52 and in stock on 22 August and again on 3 September 2026, the 20 August sale price of $46.99 having ended.
The thing to hold onto: the tea didn’t get worse and nobody is gouging you. Twelve thousand ageing farm households, the hardest labour on the farm, forty-five processing plants built in a decade, stone mills turning out forty grams an hour — that was always what stood behind the bowl. It just used to be a domestic secret rather than a global bottleneck.
