Shizuoka, the prefecture where I live, in Japan, is very famous for it's green tea. Shizuoka accounts for 40% of Japan's overall tea production. The prefecture conducts cutting-edge research on the functional benefits of green tea. Japan is well known for its love of tea and the beverage plays an important role in Japanese food culture. Green tea is by far the most commonly produced and consumed variety and ocha, the Japanese word for tea. Ocha is almost exclusively used to refer to the “green” variety.
