What Is Driving the Global Matcha Boom? A Japan Supplier's View (2026)

Today, May 21, is International Tea Day — and there is no better moment to take a clear-eyed look at what is really happening inside Japan's tea industry amid the unprecedented global matcha boom.

A Boom with a Warning Label

Matcha lattes are everywhere in the United States, and demand from American cafes, restaurants, and food brands has never been stronger. Japan's tea exports have surged accordingly. Yet industry insiders in Japan are sounding the alarm rather than celebrating. According to a May 2026 report by The Asahi Shimbun, Prof. Nobuyuki Nakamura, Director of the Tea Science Comprehensive Research Center at the University of Shizuoka, described the current state of Japan's tea industry with a single word: "chaos."

"I am genuinely worried about what comes next," Prof. Nakamura told the Asahi Shimbun. His concern is shared widely among tea producers, wholesalers, and researchers — and it has direct implications for U.S. buyers who depend on a stable, high-quality supply of Japanese matcha.

Production Shift Away from Other Teas

The financial incentives for growing matcha are so strong that tea farmers across Japan are converting their fields to matcha production — specifically, the shade-grown tea leaf known as tencha (碾茶), the raw material from which matcha is ground. This shift is squeezing the supply of other traditional Japanese teas.

In March 2026, Ippodo Tea Co. (一保堂茶舗), one of Kyoto's most respected tea merchants with nearly 300 years of history, announced purchase limits on hojicha (焙じ茶 — roasted green tea) and genmaicha (玄米茶 — green tea blended with roasted brown rice). On its website, the company noted that "production conversion to matcha is expected to accelerate further next year driven by high prices," and that a large-scale return to non-matcha tea production is unlikely given the significant price gap.

Note: Hojicha and genmaicha are traditional Japanese teas that have grown popular in the U.S. market as café ingredients. Their supply tightening is a direct consequence of the matcha boom.

Record Closures in the Tea Manufacturing Sector

The matcha concentration is also driving an alarming wave of business closures. According to Teikoku Databank (帝国データバンク), Japan's leading corporate credit research firm, there were 13 tea manufacturing business closures in 2025 — the highest number on record. The cause is the same: as demand and prices for matcha raw materials soar, producers of other tea types can no longer sustain operations or pass costs on to buyers.

A Teikoku Databank analyst noted that "the situation has not improved entering 2026, and the concentration on matcha and rising prices suggest conditions are worsening." For U.S. importers, this means the long-term supply base for all Japanese teas — including matcha — is under structural pressure.

Succession Crisis: Who Will Grow Tomorrow's Matcha?

Even with higher prices boosting tea farmer incomes in the short term, the industry's aging workforce problem remains unsolved. Prof. Nakamura points out that there is still no meaningful sign of improvement in the successor shortage among farm households. "A one-time bubble will eventually burst," he warned. "Unless the industry can offer stability over the long term, the next generation simply will not enter the field."

Instead, the new entrants capitalizing on the boom are described by industry veterans as "outsiders" — speculators treating matcha as a commodities trade rather than a craft. Hideki Kuwahara (76), a tea merchant in Uji, Kyoto, noted that companies seeking Uji matcha deals have surged, comparing the dynamic to the Taiwanese tapioca (boba) craze: "Matcha is profitable right now. Once the boom ends, they will leave just as quickly."

Note: Uji, Kyoto (宇治) is considered the historic heartland of Japanese matcha production, and "Uji matcha" is one of the most recognized quality designations in the global tea market.

What This Means for U.S. Café and Restaurant Buyers

New-crop tea prices are hitting record highs across Japan's producing regions in May 2026. For U.S. buyers, several practical considerations emerge from these developments:

• Secure reliable sourcing partnerships now. As speculative players enter the market, the distinction between authentic, traceable Japanese matcha and lower-grade or mislabeled alternatives is becoming harder to verify. Working with established, long-term Japanese suppliers is more important than ever.
• Understand what you are buying. Industry bodies in Japan define "matcha" narrowly: it must be ground from shade-grown tencha leaves using stone mills. Powdered green teas that do not meet this standard — often cheaper and more widely available — cannot properly be called matcha under this definition.
• Plan for price volatility. With record closures, an aging farming workforce, and speculative pressure, supply-side disruptions are a real risk. Building adequate inventory buffers and locking in forward pricing where possible is prudent sourcing strategy.
• Monitor competition from Chinese matcha. Cheaper Chinese-produced matcha powder is gaining ground in overseas markets. Knowing your source and communicating provenance clearly to your customers protects your brand positioning and customer trust.

The Long View

Prof. Nakamura's final warning is worth quoting directly: "I have been thinking recently about what comes after this matcha bubble ends. Tea is an agricultural product — once the production base collapses, it is very hard to rebuild."

For American cafes and foodservice businesses whose menus and brand identities are built around authentic Japanese matcha, the health of Japan's tea industry is not a distant concern. It is a supply chain issue. The matcha boom has created real opportunity — but the structural challenges developing beneath the surface deserve the attention of every serious buyer in the U.S. market.
