Sayama tea (狭山茶, Sayama-cha) is a type of green tea leaves produced mainly in the southwestern region of Saitama Prefecture and a small neighboring area in Northwestern Tokyo. In comparison to teas from other tea-growing regions in Japan, Sayama Tea is characterized with its thick leaves. This is because the region is considered to be fairly north, and the cool climate, which sometimes causes frost in winter, making trees unable to survive without thick leaves.[1] | ||||||
