Of Japan's 47 prefectures (provinces), Shizuoka, Kagoshima and Mie are the three major tea-producing regions. Shizuoka, located in the area between Mt. Fuji and the Pacific coast west of Tokyo, is Japan's most prolific tea-growing region, accounting for over 40% of Japan's commercial production each year. Next is Kagoshima, in southern Kyushu in the far southwest of Japan's main archipelago, which produces about 20% of Japan's tea. Third is Mie, in central Japan, famous for its long history of tea cultivation. Other important tea-growing regions include the areas of the ancient capitals—Nara and Kyoto—where Japanese Buddhism has its roots, and various parts of Kyushu, with its comparatively mild climes.
