Walk into a tea shop in Tokyo in early 2026 and you may still find a sign you would not have seen a few years ago: one tin per customer. Some of Japan's most famous matcha houses began rationing their powder in October 2024, and premium auction prices have set records. Meanwhile, cafés from Sydney to Los Angeles keep adding matcha lattes to their menus. Two things are true at once — the world wants more matcha than ever, and Japan cannot make it fast enough. This is the story of how a centuries-old ceremonial tea became a global consumer craze, why the supply is straining, and whether the boom is built to last.
The trickier part is separating what is measured from what is merely felt. "Matcha is everywhere" is a vibe; export tonnage and auction prices are data. A viral latte trend is a correlate of the boom; heat-damaged bushes and a five-year planting lag are causes of the shortage. And a research firm's forecast is a projection, not an audited fact. Keeping those layers apart is the only way to understand what is really happening.

What the numbers actually show
Start with the trade statistics, because they are the firmest ground. In fiscal 2025 (the year ending March 2026), Japan's green tea exports reached 13,125 tonnes, up 42% from the previous year, while the value roughly doubled to ¥84.7 billion as prices climbed. Powdered tea — overwhelmingly matcha — made up about 70% of that export volume [source: The Japan Times, 2026]. A year earlier, exports had already risen 25% by value to ¥36.4 billion (around US$252 million) and 16% by volume [source: Reuters, 2025]. Tellingly, Japan's own tea imports also jumped in fiscal 2025, rising 82% by volume to 5,801 tonnes as domestic supply tightened [source: The Japan Times, 2026].
Production tells the same directional story. Japan produced 5,336 tons of tencha — the shade-grown leaf that is ground into matcha — in 2024, about 2.7 times the level of a decade earlier [source: Reuters, 2025]. Output of tencha rose for four straight years through 2024, even as shipments of other green teas such as sencha fell [source: The Japan Times, 2026].
Prices are the clearest stress signal. At a Kyoto tencha auction in May 2025, leaf fetched ¥8,235 per kilogram — a 170% jump from a year earlier and well above the previous record of ¥4,862 set in 2016 [source: Reuters, 2025]. These are measured figures, not impressions. Anecdotes about a small tin quadrupling in price at retail circulate widely, but they are harder to verify than auction data, so treat them as directional rather than definitive.
Why the world suddenly wants matcha
The demand side is easier to feel than to measure precisely. Matcha has migrated from the tea ceremony to the café counter and the wellness aisle: the matcha latte, the matcha soft-serve, the bright-green baked good. Social media has amplified all of it, turning a photogenic drink into native content. One Japanese online seller, Tealife, said matcha demand from its customers "grew ten-fold last year" and that it was "basically always out of stock" [source: Reuters, 2025].
That last figure deserves a caveat. One retailer's ten-fold jump is a vivid signal, but it is that seller's experience, not a national demand statistic — the kind of single data point that is easy to mistake for the whole market. What we can say with confidence is that the measured outcome of rising demand — exports up 42% by volume in a year — is real. The café-and-social-media explanation is a plausible driver of that number, but the number is the fact; the narrative around it is the interpretation.
It also matters that demand is now global and concentrated on one product. Buyers who once spread across many Japanese teas are converging on matcha specifically, which puts pressure on a narrow slice of the supply chain rather than the whole.
How big is the matcha market, then? Here the honest answer is that no one precisely knows. Private research firms publish estimates that disagree wildly — one puts the global matcha market near US$480 million in 2024, growing to roughly US$760 million by 2030, while another projects the industry will reach about US$4.5 billion within a few years. Those figures differ by nearly an order of magnitude because they define "the market" differently and are not independently audited. They are useful as a sign that businesses expect growth, but they should be read as projections, not measured facts — the same caution that applies to any company forecast.
Why supply can't turn on a dime
Here is the crucial distinction: surging demand did not, by itself, create the shortage. A shortage happens when demand meets a supply that cannot flex. Several structural constraints, largely unrelated to the latest viral moment, explain why Japan cannot simply produce more matcha this season.
Weather and a concentrated harvest
Record heat in the summer of 2024 damaged tea bushes and cut yields. A Kyoto grower, Masahiro Yoshida, harvested 1.5 tons in 2025, down about 25% from a typical 2 tons, explaining that "the bushes were damaged, so we couldn't pluck as many leaves" [source: Reuters, 2025]. Because Kyoto accounts for roughly a quarter of Japan's tencha, a regional heat shock ripples across a large share of national supply [source: Reuters, 2025].
The five-year lag
Even when prices scream for more supply, growers cannot respond quickly. A newly planted tea bush takes about five years to reach full harvestable maturity, and tencha specifically must be shaded for weeks before picking and then processed in specialized facilities. That biological and industrial lag means today's high prices can only expand supply years from now, not this spring.
An aging, shrinking farmer base
The deepest constraint predates the boom entirely. The number of farms commercially cultivating tea in Japan fell from 53,687 in 2000 to 12,325 in 2020 — a decline of roughly 77% in two decades — according to the national agricultural census, and the average tea farmer is around 65 years old [source: MAFF, 2020]. A boom cannot quickly reverse a generation of consolidation and aging.
A shift in what farmers grow
One response has been to reallocate fields toward tencha, which now commands premium prices, and away from sencha and other leaf teas. That helps matcha supply at the margin, but it is a reshuffling of a fixed base rather than a rapid expansion — and it comes at the expense of Japan's other teas.
Rationing, price spikes, and a policy response
Faced with tight supply, sellers and the government have both moved. In October 2024, two of Japan's best-known houses, Ippodo and Marukyu Koyamaen, introduced purchase limits for the first time, citing short supply; Ippodo, for instance, capped orders at 12 units per customer every 60 days and raised the price of its top-tier Ummon matcha by 53% [source: TIME, 2025]. Those are company statements about their own products — accurate as far as they go, but specific to premium lines rather than a market-wide price index.
On the policy side, Japan's Ministry of Agriculture, Forestry and Fisheries has signaled support for expanding tencha, including subsidies to help offset the cost of converting fields [source: MAFF, 2025]. There is also a quieter countercurrent in the data: even as exports surged, a record 13 domestic tea producers shut down or suspended operations in 2025, up from eight the year before [source: The Japan Times, 2026]. A boom for some is not a boom for all.
The wellness claims: evidence vs enthusiasm
Much of matcha's appeal rides on health positioning, so it is worth being careful about what the science actually supports. Because matcha is whole shade-grown leaf ground to powder and whisked into water, a serving delivers more of certain compounds — notably the catechin EGCG (epigallocatechin gallate), the amino acid L-theanine, and caffeine — than a cup of steeped green tea, according to peer-reviewed reviews of its composition [source: Molecules, 2020].
What that means for health is more measured. Randomized trials and reviews suggest the L-theanine-plus-caffeine combination may modestly improve attention and reduce some stress markers, and a 2011 meta-analysis of 14 randomized trials found green-tea catechins significantly lowered LDL cholesterol [source: Molecules, 2020]. But much of the broader evidence for cardiovascular and metabolic benefits is smaller in effect and leans on observational studies, which show association, not proven cause — and most of it concerns green tea and catechins in general rather than matcha specifically. The honest summary: matcha is a reasonable source of some beneficial compounds and may help at the margins, but it is not a proven remedy. "May be associated with" is the right register, not "cures."
"Real" matcha: grades, origin, and authenticity
As prices rise, so does confusion about what buyers are actually getting. The familiar labels — "ceremonial grade" and "culinary grade" — are marketing and industry conventions, not a legally standardized government grading system. Roughly, ceremonial refers to first-flush leaf milled for whisking and drinking, while culinary refers to later harvests suited to lattes and baking. The distinction is real in practice but not officially codified, which leaves room for loose labeling.
Origin adds another layer. Uji, in Kyoto, is the most recognized premium name, alongside regions such as Nishio, Kagoshima, and Shizuoka. With demand hot and supply short, trade bodies have warned that some products marketed as matcha may be mislabeled or not genuinely Japanese. That is a buyer-beware caution reported by industry groups rather than a quantified fraud rate, but it points to a real tension: a scarce, high-status product invites imitation. For consumers, the practical takeaways are to check origin, buy from reputable sellers, and treat suspiciously cheap "matcha" with skepticism.
Boom or bubble? What to watch
Is the matcha boom durable or a bubble? Both cases can be argued honestly. The durability case rests on measured trends: exports and tencha output have risen for several years, and matcha has embedded itself in global café and wellness culture rather than appearing overnight. The caution case is equally grounded: social-media-driven demand can cool, supply is expanding through subsidies and field conversion even as it lags by years, and heat variability adds unpredictability. One industry figure, Marc Falzon of Ooika Co., warned of "even more dramatic price increases" before newly planted fields mature [source: Reuters, 2025] — a reminder that the near-term squeeze and the long-term expansion are on different clocks.
Rather than predict, watch the signals. Do auction prices keep setting records, or do they cool as new tencha fields come online around the end of the decade? Does export volume keep climbing, or does it plateau as prices bite? Do farmer numbers stabilize, or keep falling despite subsidies? And does global demand broaden into a durable habit, or narrow back toward a niche once the novelty fades? The answers will decide whether the great matcha shortage was a turning point or a peak — and for now, the honest position is to keep watching rather than to call it.
