Matcha's Global Boom Meets Japan's Supply Squeeze

Shizuoka's second-flush harvest wrapped up by mid-month with raw tea prices forecast to hit roughly ¥2,000 per kilogram, a record high that is up 70% year-on-year and about four times the depressed rate seen just two years ago. The rally is being driven by merchants scrambling for cheaper grades after first-flush prices already spiked, combined with a genuine drop in overall production volume. For growers, it is a rare and welcome windfall after years of thin margins. But for tea merchants further down the chain, the sudden spike in input costs is squeezing margins hard, forcing difficult decisions on inventory, pricing and contracts just as demand from both domestic and export buyers remains unpredictable.

Japanese tea prices are climbing at retail too, with reports showing increases of more than ¥200 per 100 grams as the global matcha craze collides with a shrinking domestic workforce. Behind the price rise sits a structural problem that predates the matcha boom: a severe shortage of successors willing to take over tea farms, many run by aging producers with no clear next generation. As overseas demand pulls harder on limited leaf supply, the combination of fewer farmers and more buyers is doing exactly what basic economics predicts. For importers and retailers who built pricing models around pre-boom costs, this is the clearest signal yet that cheap Japanese tea may be a thing of the past.

A deep-dive beverage industry report captures just how unusual this year has become: in 2025, autumn and winter tea leaf prices for green beverage use actually exceeded spring harvest prices, an inversion with no recent precedent. Kagoshima's average spot price for new tea in 2026 surged roughly 1.7 times year-on-year, leaving bottled and canned beverage makers with a painful dilemma — absorb the cost increase and protect margins, or risk alienating consumers with sharply higher shelf prices. The report frames this as a supply-demand environment reshaped almost overnight by matcha's global popularity, with ripple effects reaching far beyond ceremonial-grade products into everyday bottled tea.

On May 10, Japan's agriculture ministry designated 'Japanese Tea' as a protected geographic indication, the country's first national-scope agricultural GI. The move is squarely aimed at counterfeit products and increasingly competitive Chinese tea flooding global markets amid the matcha boom. The timing is notable: green tea exports hit ¥72.1 billion in 2025, double the prior year's figure, showing just how much international appetite has grown. Yet May shipment volumes fell for the first time in 21 months, an early sign that cheaper foreign matcha alternatives are starting to bite. The GI status gives Japanese producers a legal and marketing tool, but whether it can offset price competition from abroad remains an open question.

A Norinchukin Research Institute report delivers a blunt warning: Japan cannot assume its matcha export edge is permanent. China's Guizhou province plans to develop 13,000 hectares of matcha tea gardens and produce 8,000 tonnes by 2028 — more than Japan's entire tencha output of 6,278 tonnes in 2025. With significantly lower labor costs, Chinese matcha is positioned to undercut Japanese pricing and could shift buyer loyalty over time. Compounding the risk, Japan's own aggressive pivot from sencha toward tencha production is tightening domestic green tea supply, pushing imports up to 4,610 tonnes in 2025. The report urges diversification rather than an all-in matcha bet.
