Jack Bean Tea 100% PURE PREMIUM

The natamame-bean is an abundant source of vital energy and is said to have been the model for the bean in the nursery tale “Jack and the Beanstalk.” Since the old days, as the tea is made from sword beans and is good for one’s health, the grandfathers and grandmothers in families on farms customarily drink this tea. We use 100% Tamba sword beans, which are grown in organic fertilizer without the use of any pesticides or fertilizers containing chemicals. When you drink this tea, you will feel the faint sweetness and a sense of nostalgia. It is a taste that you can enjoy with your whole family.
