the most popular form of tea in Japan, representing 80 percent of all tea produced each year. Automation At the end of the Meiji era (1868–1912), machine manufacturing of green tea was introduced and began replacing handmade tea. Machines took over the processes of primary drying, tea rolling, secondary drying, final rolling, and steaming. In the 20th century, automation contributed to improved quality and reduced labour. Sensor and computer controls were introduced to machine automation so unskilled workers can produce superior tea without compromising quality. Notes References • Japan Cultural history of Japan
