Sakura is virtually one of the national flowers in Japan. Since all of us love and feel overexcited to see the flower, only seeing it is not enough. Cherry blossoms and leaves are pickled, and both are used as food ingredients to give a fragrance.
The picture (above) is sakura cha, tea (or hot water) simply poured over the pickled sakura in a teacup. Other than spring, the tea is often drunk at festive events like weddings, too.
