History AOI Tea CompanyThe history of matcha green tea dates back several centuries. In 1271, tea cultivation began in Nishio, Japan, by the priest Shoichi, founder of the temple of Jissoji. Shoichi’s temple was in constant competition with the neighboring temple of Shonenji over rights to the nearby tea plants. For more than 400 years, these two temples battled for ownership until in 1692, a judgment awarded the coveted plants to Jissoji.

Nearly two hundred years later, after the Meiji Restoration of 1868, matcha production was finally embraced in Nishio. The chief priest of a nearby Buddhist monastery named Jundo Adachi introduced a new variety of tea and production techniques from Uji, which was a major production center of dried green tea powder.
