Japanese tea - 茶
Originally, the green tea tree already existed in the wild, in the mountainous regions of Japan, and was called "Sancha" (mountain tea).
Extracts of this plant have been used as a medicinal infusion.
But it was in 805 that tea was really discovered in Japan. Japanese buddhist monks Saicho and Kukai who had gone to study China brought tea seeds to Japan. These were sown in the first tea garden in Saga Prefecture, southern Japan.
Then Emperor Saga is said to have promoted the cultivation and consumption of green tea. Then he was reportedly invited to a buddhist temple, Bonshakuji temple, and green tea was reportedly served. It was at this time that green tea would have been recognized for its tonic and curative effect. Buddhist monks are said to have subsequently continued to promote tea and its production methods, which they imported from China. The monk Dogen would have imported tea-related utensils and invented the tea ceremony in the 1200s.
