The influence of cultivation method on the functional components of persimmon leaf tea was investigated using cv. 'Saijo'. Suitable cultivation methods are as follows : ① heavy pruning during winter for the formation of succulent shoots, ② application of double the regular quantity of fertilizer to enhance tree growth, and ③ harvesting of all succulent shoots at each harvest. The leaves harvested in August showed about 50～70% lower ascorbic acid concentration than those harvested in June, resulting in a different leaf quality.
