Symbolic trees representing each prefecture in Japan are planted in the northwestern corner of Ninomaru enceinte.
Such trees have been donated from each prefecture and there are total of 260, covering 30 varieties.

The small Ninomaru Garden at the foot of the castle hill was originally planted in 1636 by Kobori Enshu, a famed landscape artist and garden designer, but it was destroyed by fire in 1867.
The current layout was created in 1968, based on a plan drawn up during the reign of ninth shogun, Tokugawa Ieshige.
