The shading treatment of tea plants for a few weeks before the harvest enriches tea leaves with free amino acids such as theanine and brings the specially flavor-rich quality of green tea. There are difficulties in producing the flavor-rich green tea in the midsummer under the shading treatment because of the excessively high temperature condition. The evaporative cooling treatment by sprinkling water over tea plants intermittently in the daytime dropped temperatures of leaves and the ambient air by 3°C, and further the radiative cooling treatment by opening the shade screen net during the nighttime dropped the temperatures by 2°C. Thus, these passive cooling treatments were demonstrated effectively to drop temperatures of leaves and the ambient air in the summer production of green tea.
