We considered a thermal imaging method to objectively estimate the surface temperature of tea plant bushes. The different temperatures of eight tea bush varieties were compared using a globe thermometer. Tea bush temperature was measured in midsummer, and temperature was high in varieties where water stress was remarkable. In the tea bush varieties Yabukita and Kanayamidori, which had a high bush temperature and high water stress during the summer, their irrigation effects were high. It was considered that by identifying the tea plants that undergo water stress during the summer based on the bush temperature and preferentially irrigating them, it would be possible to reduce the adverse effects of subsequent growth and drought.
