Tea production methods using hand-kneading wre invented in 1738 by Nagatani Soen, who was a tea planter in Ujitawara. They were developed as they proved to result in superior color, aroma, and flavor compared to that of conventional tea and spread throughout the country. The Uji-cha Production Methods and Techniques Preservation Society took over the task of protectng these valiable techniques as Uji City's intangible culture properties.
