A global surge in demand for matcha, the vibrant green powdered tea rooted in Japanese culture, has caused significant supply shortages and rising prices worldwide. The popularity of matcha, driven by social media trends and a post-pandemic tourism boom in Japan, has turned the once-niche product into a global sensation. From Starbucks lattes in the UK to Krispy Kreme doughnuts in Singapore, matcha's distinctive flavour and health benefits have captured the attention of millennials and Gen Z consumers seeking wellness-oriented beverages.

The powder is derived from tencha leaves, a variety of green tea grown under shade to enhance its signature umami and sweetness. This cultivation process is highly specialized and time-consuming, with production limited by the traditional stone grinding method that yields only about 40 grams of matcha per hour. However, recent record-breaking heatwaves in Japan—especially in the Kyoto region, which produces roughly a quarter of the country’s tencha—have severely impacted crops. Tea farmers report up to a 25% drop in yield and lower-quality harvests, straining the already tight supply chain.

These climatic challenges compound deeper structural issues in Japan’s tea industry, such as an ageing farmer population and insufficient younger entrants to maintain production levels. As international demand skyrockets, some major producers like Marukyu Koyamaen and Ippodo Tea have curtailed retail sales or imposed customer purchase limits to manage shortages. Retailers in renowned matcha hubs such as Uji, Kyoto face empty shelves, often with stock disappearing rapidly due to tourist purchases.

The economic impact is notable: auction prices for tencha leaves in Kyoto have hit record highs, reaching over 8,200 yen per kilogram in early 2025—a 70% increase compared to the previous year and nearly double the prices seen in 2016. Export values of Japanese green tea, including matcha, climbed by 25% to 36.4 billion yen in 2024, reflecting strong global appetite for the product. According to Japan’s agricultural ministry, matcha production has nearly tripled over the past decade, yet current supply constraints mean prices are expected to continue rising alongside persistent shortages.

Consumer groups and industry insiders urge more mindful consumption amid the craze, highlighting concerns over hoarding and the use of high-grade matcha in recipes where its delicate flavour is often lost. Traditional tea masters emphasise the cultural significance of matcha as integral to Japanese heritage, viewing the recent surge as an opportunity to introduce wider audiences to Japan’s tea ceremony rituals.

The long-term outlook remains cautious. Although new cultivation areas and production techniques are being explored to meet demand, the time lag for new tea bushes to mature—around five years—means immediate relief is unlikely. Climate volatility further complicates planning for growers. Meanwhile, Japan faces similar agricultural challenges with other staples, such as rice, where extreme weather and natural disasters have led to price spikes and supply disruptions, underscoring broader systemic vulnerabilities in the country’s food sector.

Overall, the global thirst for matcha reflects shifting consumer preferences towards health-conscious and culturally rich food experiences. Yet, it also reveals the delicate balance between innovation, tradition, and sustainability in agriculture as global markets increasingly intersect with local practices.
