Undoubtedly, 'Ocha' (green tea) is Japan's most popular beverage. The Ministry of Internal Affairs and Communication reports that in 2004, a Japanese family spent an average of 5,575 yen buying a little over a kilo of green tea. Tea drinking is traced back to China, but it's reported that in 815, Eichu, a Buddhist monk served Japan's Emperor Saga a cup of tea. Tea seeds were probably brought to Japan in 1191 by Yousai, a Zen Buddhist who had studied in China. Tea soon became popular and a gradual cultivation began so that bythe 15th century affluent people were enjoying 'Macha', green tea in powder form. Sen Rikyu, an affluent merchant and great tea master established 'Chanoyu', the beloved tea ceremony that was further developed by his descendants over 4 centuries. In the 16th century, Ingen, a Chinese Buddhist introduced 'Sencha', a loose leaf tea, from the Chinese mainland. During the long Tokugawa Shogunate, tea consumption increased unabated and steamed 'Sencha' was invented in the 18th century. Fresh tea leaves soon begin to oxidize as natural enzymes inside the leaf are released immediately after plucking however applying heat stops the process thus preventing harmful oxidation. Still a popular method, the 'Sencha' then brought from China was produced by pan firing. Presently, however, almost all green tea grown in Japan is processed by steaming; this method represents the most essential difference between the two teas. After the Meiji Revolution in 1868, the Japanese government actively promoted tea production that,second only to silk, had become the most important export. Tea processing technology developed rapidly and domestic tea consumption kept pace with Japan's remarkable economic performance in the mid-50s.
