Today, green tea enjoys global recognition, celebrated both for its rich cultural heritage and its health benefits. Its popularity has extended far beyond Asia, with green tea available in a wide variety of forms—loose leaf, powdered, bagged, and blended with flavors such as jasmine and mint. Countries like the U.S. and the U.K. have embraced green tea, not just as a beverage, but also as an ingredient in health foods, skincare products, and supplements.
20th Century: Globalization and Health Renaissance
The 20th century saw green tea emerge globally, especially after World War II, as more people became aware of its health benefits. Scientific research began to highlight the high antioxidant content of green tea, linking it to reduced risks of heart disease, cancer, and other chronic conditions. As the global wellness movement gained momentum, green tea found renewed popularity in Europe, North America, and beyond.
Japan and China continued to lead green tea production, while new producers emerged in places like India and Sri Lanka, traditionally associated with black tea. Indian green tea, grown primarily in Assam and Darjeeling, started to gain international recognition in the late 20th century.
Expansion to the Americas
In the 18th century, green tea was also introduced to the American colonies. It was a common beverage in the early years of American history, until the Boston Tea Party in 1773, when the protest against British tea taxes led to a decline in tea consumption. Coffee eventually became more popular in the U.S., though green tea never completely disappeared from the American market.

Green Tea in Southeast Asia
Green tea also spread to other parts of Asia, particularly Southeast Asia, through trade routes established during the height of the Chinese Empire. While countries like Thailand and Vietnam are more associated with black and oolong teas today, green tea still plays a role in local traditions and cuisine. In Vietnam, for example, green tea (locally known as chè xanh) is consumed both as a daily drink and in social gatherings.
Spread to Korea
Green tea’s journey to Korea occurred in the 7th century, around the time when Buddhist monks and scholars traveled between China, Korea, and Japan. Like Japan, Korea’s introduction to tea was rooted in its connection to Buddhism. Tea rituals became an important part of monastic life, symbolizing purity and mindfulness. Over the centuries, Korean green tea evolved with its own distinctive flavors and brewing styles, particularly in regions like Boseong, known for its high-quality green tea.
Introduction to Japan
Green tea was introduced to Japan in the early 9th century by Japanese Buddhist monks who studied in China. These monks, such as Saicho and Kukai, brought back tea seeds and the practice of drinking tea as a way to aid meditation. Initially, tea was consumed primarily in monasteries for its calming and focus-enhancing properties.
By the 12th century, the monk Eisai introduced matcha, powdered green tea, to Japan after visiting Chinese temples. He also wrote Kissa Yojoki (“Drinking Tea for Health”), a book extolling the health benefits of green tea, which contributed to its wider adoption in Japanese society. Over time, green tea became a central part of Japanese culture, culminating in the development of the chanoyu (tea ceremony), which remains a revered tradition today.

The History and Origins of Green Tea
Origins in Ancient China
The history of green tea dates back thousands of years, beginning in ancient China, where the tea plant Camellia sinensis was first cultivated. According to legend, green tea was discovered around 2737 BCE by Emperor Shen Nong, who accidentally boiled water containing tea leaves. Intrigued by the aroma and taste, he is said to have enjoyed its refreshing qualities and later realized its medicinal benefits. From then on, green tea became a staple in Chinese culture, both as a beverage and a healing tonic. By the Han Dynasty (206 BCE–220 CE), green tea was already being enjoyed in various forms, and by the Tang Dynasty (618–907 CE), it became widely accessible, cementing its role in Chinese life.
